Background:Gout is an inflammatory crystal arthropathy characterised by hyperuricaemia and sodium urate crystal deposition. Both gout and subclinical hyperuricaemia are associated with adverse cardiovascular outcomes. Several studies have found gout to cause an increased risk of cardiovascular disease, but the evidence is not unanimous. The conflicting evidence has made it difficult to establish the extent of the cardiovascular risk to patients with gout.Objectives:To describe the incidence and prevalence of cardiovascular disease in gout, compare these results with non-gout controls.Methods:PubMed, Scopus and Web of Science were systematically searched in January 2021 for studies reporting prevalence of any cardiovascular disease in a gout population. Studies with non-representative sampling, where a cohort had been used in another study, small sample size (< 100) and where gout could not be distinguished from other rheumatic conditions were excluded. Sample size, prevalence of the investigated cardiovascular disease, definition of gout and cardiovascular disease, demographic data, data source and any comparisons with non-gout controls were extracted from each study. Where prevalence data was reported in ≥3 cohorts meta-analysis was performed using random-effect models.Results:Of the 6164 titles identified, 105 full texts were assessed for eligibility with 30 included in the review, producing a gout population of 1,125,988. Pooled prevalence estimates were calculated for six cardiovascular diseases: heart failure (8.73%; 95% confidence interval (CI), 2.85 – 23.76), cerebrovascular accident (4.27%; 95% CI, 1.83 – 9.67), myocardial infarction (2.82%; 95% CI, 1.58 – 5.01), venous thromboembolism (2.05%; 95% CI, 1.22 – 3.43), hypertension (63.94%; 95% CI, 24.51 – 90.64) and cardiovascular mortality (4.75%; 95% CI, 3.56 – 6.31). Twenty studies reported comparisons with non-gout controls, illustrating an increased risk in the gout group across all cardiovascular diseases, particularly for myocardial infarction.Conclusion:Cardiovascular diseases are more prevalent in patients with gout and should prompt vigilance from clinicians to the need to assess and stratify cardiovascular risk. These results are in line with other studies which have shown an increased cardiovascular risk for sufferers of hyperuricaemia, highlighting the need for future research to explain this finding. There are limited studies in the literature investigating less common cardiovascular conditions, illustrating the need for future work if a more thorough picture of prevalence is to be established.Figure 1.Forest plots of pooled prevalence of: (A) 8.73% for heart failure, (B) 4.27% for cerebrovascular accident, (C) 2.82% for myocardial infarction, (D) 2.05% for venous thromboembolism, (E) 63.94% for hypertension and (F) 4.75% for cardiovascular mortality.Disclosure of Interests:None declared.

AbstractThe aims of this systematic review and meta-analysis were to describe prevalence of cardiovascular disease in gout, compare these results with non-gout controls and consider whether there were differences according to geography. PubMed, Scopus and Web of Science were systematically searched for studies reporting prevalence of any cardiovascular disease in a gout population. Studies with non-representative sampling, where a cohort had been used in another study, small sample size (< 100) and where gout could not be distinguished from other rheumatic conditions were excluded, as were reviews, editorials and comments. Where possible meta-analysis was performed using random-effect models. Twenty-six studies comprising 949,773 gout patients were included in the review. Pooled prevalence estimates were calculated for five cardiovascular diseases: myocardial infarction (2.8%; 95% confidence interval (CI)s 1.6, 5.0), heart failure (8.7%; 95% CI 2.9, 23.8), venous thromboembolism (2.1%; 95% CI 1.2, 3.4), cerebrovascular accident (4.3%; 95% CI 1.8, 9.7) and hypertension (63.9%; 95% CI 24.5, 90.6). Sixteen studies reported comparisons with non-gout controls, illustrating an increased risk in the gout group across all cardiovascular diseases. There were no identifiable reliable patterns when analysing the results by country. Cardiovascular diseases are more prevalent in patients with gout and should prompt vigilance from clinicians to the need to assess and stratify cardiovascular risk. Future research is needed to investigate the link between gout, hyperuricaemia and increased cardiovascular risk and also to establish a more thorough picture of prevalence for less common cardiovascular diseases.

AbstractObjectivesTo conduct a systematic review and meta-analysis of the effects of rosiglitazone treatment on cardiovascular risk and mortality using multiple data sources and varying analytical approaches with three aims in mind: to clarify uncertainties about the cardiovascular risk of rosiglitazone; to determine whether different analytical approaches are likely to alter the conclusions of adverse event meta-analyses; and to inform efforts to promote clinical trial transparency and data sharing.DesignSystematic review and meta-analysis of randomized controlled trials.Data sourcesGlaxoSmithKline’s (GSK’s) ClinicalStudyDataRequest.com for individual patient level data (IPD) and GSK’s Study Register platforms, MEDLINE, PubMed, Embase, Web of Science, Cochrane Central Registry of Controlled Trials, Scopus, and ClinicalTrials.gov from inception to January 2019 for summary level data.Eligibility criteria for selecting studiesRandomized, controlled, phase II-IV clinical trials that compared rosiglitazone with any control for at least 24 weeks in adults.Data extraction and synthesisFor analyses of trials for which IPD were available, a composite outcome of acute myocardial infarction, heart failure, cardiovascular related death, and non-cardiovascular related death was examined. These four events were examined independently as secondary analyses. For analyses including trials for which IPD were not available, myocardial infarction and cardiovascular related death were examined, which were determined from summary level data. Multiple meta-analyses were conducted that accounted for trials with zero events in one or both arms with two different continuity corrections (0.5 constant and treatment arm) to calculate odds ratios and risk ratios with 95% confidence intervals.Results33 eligible trials were identified from ClinicalStudyDataRequest.com for which IPD were available (21 156 patients). Additionally, 103 trials for which IPD were not available were included in the meta-analyses for myocardial infarction (23 683 patients), and 103 trials for which IPD were not available contributed to the meta-analyses for cardiovascular related death (22 772 patients). Among 29 trials for which IPD were available and that were included in previous meta-analyses using GSK’s summary level data, more myocardial infarction events were identified by using IPD instead of summary level data for 26 trials, and fewer cardiovascular related deaths for five trials. When analyses were limited to trials for which IPD were available, and a constant continuity correction of 0.5 and a random effects model were used to account for trials with zero events in only one arm, patients treated with rosiglitazone had a 33% increased risk of a composite event compared with controls (odds ratio 1.33, 95% confidence interval 1.09 to 1.61; rosiglitazone population: 274 events among 11 837 patients; control population: 219 events among 9319 patients). The odds ratios for myocardial infarction, heart failure, cardiovascular related death, and non-cardiovascular related death were 1.17 (0.92 to 1.51), 1.54 (1.14 to 2.09), 1.15 (0.55 to 2.41), and 1.18 (0.60 to 2.30), respectively. For analyses including trials for which IPD were not available, odds ratios for myocardial infarction and cardiovascular related death were attenuated (1.09, 0.88 to 1.35, and 1.12, 0.72 to 1.74, respectively). Results were broadly consistent when analyses were repeated using trials with zero events across both arms and either of the two continuity corrections was used.ConclusionsThe results suggest that rosiglitazone is associated with an increased cardiovascular risk, especially for heart failure events. Although increased risk of myocardial infarction was observed across analyses, the strength of the evidence varied and effect estimates were attenuated when summary level data were used in addition to IPD. Because more myocardial infarctions and fewer cardiovascular related deaths were reported in the IPD than in the summary level data, sharing IPD might be necessary when performing meta-analyses focused on safety.Systematic review registrationOSF Home https://osf.io/4yvp2/.

AbstractImportanceOn 11th March, the World Health Organization declared a pandemic of COVID-19. There are over 1 million cases around the world with this disease and it continues to raise. Studies on COVID-19 patients have reported high rate of cardiovascular disease (CVD) among them and patients with CVD had higher mortality rate.ObjectivesSince there were controversies between different studies about CVD burden in COVID-19 patients, we aimed to study cardiovascular disease burden among COVID-19 patients using a systematic review and meta-analysis.Data SourcesWe have systematically searched databases including PubMed, Embase, Cochrane Library, Scopus, Web of Science as well as medRxiv pre-print database. Hand searched was also conducted in journal websites and Google Scholar.Study SelectionStudies reported cardiovascular disease among hospitalized adult COVID-19 patients with mortality or ICU admission (primary outcomes) were included into meta-analysis. In addition, all of studies which reported any cardiovascular implication were included for descriptive meta-analysis. Cohort studies, case-control, cross-sectional, case-cohort and case series studies included into the study. Finally, 16 studies met the inclusion criteria for primary outcome and 59 studies for descriptive outcome.Data Extraction and SynthesisTwo investigators have independently evaluated quality of publications and extracted data from included papers. In case of disagreement a supervisor solved the issue and made the final decision. Quality assessment of studies was done using Newcastle-Ottawa Scale tool. Heterogeneity was assessed using I-squared test and in case of high heterogeneity (>%50) random effect model was used.Main Outcomes and MeasuresMeta-analyses were carried out for Odds Ratio (OR) of mortality and Intensive Care Unit (ICU) admission for different CVDs and Standardized Mean Difference (SMD) was calculated for Cardiac Troponin I. We have also performed a descriptive meta-analysis on different CVDs.ResultsSixteen papers including 3473 patients entered into meta-analysis for ICU admission and mortality outcome and fifty-nine papers including 9509 patients for descriptive outcomes. Results of meta-analysis indicated that acute cardiac injury, (OR: 15.94, 95% CI 2.31-110.14), hypertension (OR: 1.92, 95% CI 1.92-2.74), heart Failure (OR: 11.73, 95% CI 5.17-26.60), other cardiovascular disease (OR: 1.95, 95% CI 1.17-3.24) and overall CVDs (OR: 3.37, 95% CI 2.06-5.52) were significantly associated with mortality in COVID-19 patients. Arrhythmia (OR: 22.17, 95%CI 4.47-110.04), acute cardiac injury (OR: 19.83, 95%CI 7.85-50.13), coronary heart disease (OR: 4.19, 95%CI 1.27-13.80), cardiovascular disease (OR: 4.17, 95%CI 2.52-6.88) and hypertension (OR: 2.69, 95%CI 1.55-4.67) were also significantly associated with ICU admission in COVID-19 patients.ConclusionOur findings showed a high burden of CVDs among COVID-19 patients which was significantly associated with mortality and ICU admission. Proper management of CVD patients with COVID-19 and monitoring COVID-19 patients for acute cardiac conditions is highly recommended to prevent mortality and critical situations.Key PointsQuestionAre cardiovascular disease associated with mortality and Intensive Care Unit admission (ICU) of COVID-19 patients?FindingsIn this systematic review and meta-analysis, acute cardiac injury, hypertension, heart failure and overall cardiovascular diseases were significantly associated with mortality in COVID-19 patients. Arrhythmia, coronary heart disease, hypertension, acute cardiac injury and other cardiovascular disease were significantly associated with ICU admission of COVID-19 patients.MeaningCardiovascular diseases have significant role in mortality and disease severity of COVID-19 patients. COVID-19 patients need to be carefully monitored for cardiovascular diseases and managed properly in case of acute cardiac conditions.

Abstract There is increased risk of cardiovascular disease in patients with chronic inflammatory disorders such as rheumatoid arthritis, psoriatic arthritis, and systemic lupus erythematosus. Studies have shown association between cardiovascular disease (eg, myocardial infarction, heart failure, stroke) and inflammatory bowel disease. Medications such as infliximab and adalimumab (monoclonal antibodies to tumor necrosis factor α) may help decrease the inflammatory burden and cardiovascular risk; however, there have been reports of hypertriglyceridemia and worsening of moderate to severe heart failure with these medications. Janus kinase inhibitors, such as tofacitinib, have been associated with hyperlipidemia and thromboembolism. We aim to discuss clinical and imaging modalities to assess cardiovascular risk in inflammatory bowel disease patients and review the role of various medications with respect to cardiovascular disease in this population.

ABSTRACTObjectiveTo conduct a systematic review and meta-analysis of the effects of rosiglitazone therapy on cardiovascular risk and mortality using multiple data sources and varying analytical approaches.DesignSystematic review and meta-analysis of randomized controlled trials.Data sourcesGlaxoSmithKline’s (GSK) Clinical Study Data Request (CSDR) and Study Register platforms, MEDLINE, PubMed, Embase, Web of Science, Cochrane Central Registry of Controlled Trials, Scopus, and ClinicalTrials.gov from inception to January 2019.Study selection criteriaRandomized, controlled, phase II-IV clinical trials comparing rosiglitazone with any control for at least 24 weeks in adults.Data extraction and synthesisFor analyses of trials for which individual patient-level data (IPD) were available, we examined a composite of the following events as our primary outcome: acute myocardial infarction, heart failure, cardiovascular-related deaths, and non-cardiovascular-related deaths. As secondary analyses, these four events were examined independently. When also including trials for which IPD were not available, we examined myocardial infarction and cardiovascular-related deaths, ascertained from summary-level data. Multiple meta-analyses were conducted, accounting for trials with zero events in one or all arms with two different continuity corrections (i.e., 0.5 constant and treatment arm comparator continuity correction), to calculate odds ratios and risk ratios with 95% confidence intervals.ResultsThere were 33 eligible trials for which IPD were available (21156 participants) through GSK’s CSDR. We also identified 103 additional trials for which IPD were not available from which we ascertained myocardial infarctions (23683 patients) and 103 trials for cardiovascular-related deaths (22772 patients). Among trials for which IPD were available, we identified a greater number of myocardial infarctions and fewer cardiovascular-related deaths reported in the IPD as compared to the summary-level data. When limited to trials for which IPD were available and accounting for trials with zero-events in only one arm using a constant continuity correction of 0.5, patients treated with rosiglitazone had a 39% increased risk of a composite event compared with controls (Mantel-Haenszel odds ratio 1.39, 95% CI 1.15 to 1.68). When examined separately, the odds ratios for myocardial infarction, heart failure, cardiovascular-related death, and non-cardiovascular-related death were 1.25 (0.99 to 1.60), 1.60 (1.20 to 2.14), 1.18 (0.64 to 2.17), and 1.13 (0.58 to 2.20), respectively. When all trials for which IPD were and were not available were combined for myocardial infarction and cardiovascular-related deaths, the odds ratios were attenuated (1.13 (0.92 to 1.38) and 1.10 (0.73 to 1.65), respectively). Effect estimates and 95% confidence intervals were broadly consistent when analyses were repeated including trials with zero events across all arms using constant continuity corrections of 0.5 or treatment arm continuity corrections.ConclusionsResults of this comprehensive meta-analysis aggregating a multitude of trials and analyzed using a variety of statistical techniques suggest that rosiglitazone is consistently associated with an increased cardiovascular risk, likely driven by heart failure events, whose interpretation is complicated by varying magnitudes of myocardial infarction risk that were attenuated through aggregation of summary-level data in addition to IPD.Systematic review registrationhttps://osf.io/4yvp2/What is already known on this topic-Since 2007, there have been multiple meta-analyses, using various analytic approaches, that have reported conflicting findings related to rosiglitazone’s cardiovascular risk.-Previous meta-analyses have relied primarily on summary-level data, and did not have access to individual patient-level data (IPD) from clinical trials.-Currently, there is little consensus on which method should be used to account for sparse adverse event data in meta-analyses.What this study adds-Among trials for which IPD were available, rosiglitazone use was consistently associated with an increased cardiovascular risk, likely driven by heart failure events.-Interpretation of rosiglitazone’s cardiovascular risk is complicated by varying magnitudes of myocardial infarction risk that were attenuated through aggregation of summary-level data in addition to IPD.-Among trials for which IPD were available, we identified a greater number of myocardial infarctions and fewer cardiovascular deaths reported in the IPD as compared to the summary-level data, which suggests that IPD may be necessary to accurately classify all adverse events when performing meta-analyses focused on safety.

Abstract Background : Androgen deprivation therapy (ADT) is widely being applied in men who suffered from prostate cancer, our aim is to evaluate whether ADT is associated with an excess risk of cardiovascular disease (CVD). Method : Studies comparing the the incidence of CVD between ADT group and control group were identified through literature search in electronic databases (Pubmed, Embase, Web of Science) until July 2019 and only observational studies and randomized controlled trials (RCT) were included. The estimating relative risk ratio (RR) and 95% confidence intervals (CI) were calculated through random effects meta-analyses. Result : A statistically significant association was detected for acute myocardial infarction (AMI) with RR = 1.22; 95% confidence interval CI, 1.05–1.43; P< 0.05. Significant relationship between coronary heart disease (CHD) and ADT was also observed, with summary RR=1.19; 95%CI, 1.03-1.38; P<0.05. ADT was associated with a risk increasement for heart failure (HF) with RR=1.15; 95% CI 1.01–1.33; P< 0.05. On the contrary, ADT was not associated with an increased risk of sudden cardiac death (SCD). Conclusions : From this study, ADT is associated with increased risk of AMI, CHD, and heart failure (HF); in contrast, this association is not detected in SCD; various modalities of ADT could significantly increase the risk of CHD, AMI, except for oral anti-androgen (AA). Our meta-analysis also suggests that the long-term application of ADT in prostate cancer patients would not result in a significant increase in AMI incidence compared with short-term. Moreover, the combined application of AA and GnRH agonists would lead to a similar risk of AMI compared with orchiectomy or GnRH agonists monotherapy whereas higher risk of CHD was detected when compared GnRH agonists plus AA with orchiectomy.

The term ‘meta-analysis’ refers to a statistical method for combining the results of several (often many) studies or experiments in order to arrive at an overall conclusion about the size and variability of the measure of interest. In the context of cardiovascular disease, such studies are most often randomized trials of therapies for the prevention or treatment of cardiovascular events, such as myocardial infarction or stroke. The specialty has now witnessed several decades of success in identifying effective treatments for cardiovascular diseases, and the technique of meta-analysis of randomized trials has played an important role in this success. Not all meta-analyses are made equal, however, and it is important to be aware of the limitations of the method. This chapter considers how the technique can be best employed to guide treatment decisions, while also highlighting the limitations of meta-analysis when the information available is inadequate or potentially biased.

Background The benefits of aspirin for primary prevention of stroke are uncertain. Methods We performed a cumulative meta-analysis of trials investigating aspirin for primary prevention of cardiovascular disease with a focus on stroke. We assessed the effects of aspirin on non-fatal stroke, hemorrhagic stroke, non-fatal myocardial infarction, all-cause mortality, cardiovascular mortality, major gastrointestinal bleeding, and an analysis of net clinical effect, in populations without a history of clinical or subclinical cardiovascular disease. Summary of review results Among 11 trials (157,054 participants), aspirin was not associated with a statistically significant reduction in non-fatal stroke (odds ratio, 0.94; 95% CI, 0.85 to 1.04) but was associated with an increased risk of hemorrhagic stroke (odds ratio, 1.29; 95% CI, 1.06 to 1.56). Aspirin was not associated with a statistically significant reduction in all-cause mortality (odds ratio, 0.97; 95% CI, 0.92 to 1.03) or cardiovascular mortality (odds ratio, 0.94; 95% CI, 0.85 to 1.03). Aspirin was associated with a reduction in non-fatal myocardial infarction (odds ratio, 0.80; 95% CI, 0.69 to 0.94) and an increased risk of major gastrointestinal bleeding (odds ratio, 1.83; 95% CI, 1.43 to 2.35). Using equal weighting for non-fatal events and major bleeding, we observed no net clinical benefit with aspirin use for primary prevention. Conclusion Our meta-analysis reports no benefit of aspirin for primary stroke prevention.

Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 is an ongoing viral pandemic marked by increased risk of thrombotic events. However, the role of platelets in the elevated observed thrombotic risk in COVID-19 and utility of antiplatelet agents in attenuating thrombosis is unknown. We aimed to determine if the antiplatelet effect of aspirin may mitigate risk of myocardial infarction, cerebrovascular accident, and venous thromboembolism in COVID-19. We evaluated 22,072 symptomatic patients tested for COVID-19. Propensity-matched analyses were performed to determine if treatment with aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) affected thrombotic outcomes in COVID-19. Neither aspirin nor NSAIDs affected mortality in COVID-19. Thus, aspirin does not appear to prevent thrombosis and death in COVID-19. The mechanisms of thrombosis in COVID-19, therefore, appear distinct and the role of platelets as direct mediators of SARS-CoV-2-mediated thrombosis warrants further investigation.

Abstract Coronavirus disease-2019 (COVID-19) caused by SARS-CoV-2 is an ongoing viral pandemic marked by increased risk of thrombotic events. However, the role of platelets in the elevated observed thrombotic risk in COVID-19 and utility of anti-platelet agents in attenuating thrombosis is unknown. We aimed to determine if human platelets express the known SARS-CoV-2 receptor-protease axis on their cell surface and assess whether the anti-platelet effect of aspirin may mitigate risk of myocardial infarction (MI), cerebrovascular accident (CVA), and venous thromboembolism (VTE) in COVID-19. Expression of ACE2 and TMPRSS2 on human platelets were detected by immunoblotting and confirmed by confocal microscopy. We evaluated 22,072 symptomatic patients tested for COVID-19. Propensity-matched analyses were performed to determine if treatment with aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) affected thrombotic outcomes in COVID-19. Neither aspirin nor NSAIDs affected mortality in COVID-19. However, both aspirin and NSAID therapies were associated with increased risk of the combined thrombotic endpoint of (MI), (CVA), and (VTE). Thus, while platelets clearly express ACE2-TMPRSS2 receptor-protease axis for SARS-CoV-2 infection, aspirin does not prevent thrombosis and death in COVID-19. The mechanisms of thrombosis in COVID-19, therefore, appears distinct and the role of platelets as direct mediators of SARS-CoV-2-mediated thrombosis warrants further investigation.
