Abstract Background Heart failure (HF) is increasing in prevalence worldwide. We explored whether adults with trace and positive proteinuria were at a high risk for incident HF compared with those with negative proteinuria using a nationwide epidemiological database. Methods This is an obserevational cohort study using the JMDC Claims Database collected between 2005 and 2020. This is a population-based sample (n = 1,021,943; median age [interquartile range], 44 [37-52] years; 54.8% men). No participants had a known history of cardiovascular disease. Each participant was categorized into three groups according to the urine dipstick test results: negative proteinuria (n = 902,273), trace proteinuria (n = 89,599), and positive proteinuria (≥1+) (n = 30,071). The primary outcome was HF. The secondary outcomes were myocardial infarction, stroke, and atrial fibrillation. We performed multivariable Cox regression analyses to identify the association between the proteinuria category and incient HF and other cardiovascular disease events. Results Over a mean follow-up of 1,150 ± 920 days, 17,182 incident HF events occurred. After multivariable adjustment, hazard ratios (HRs) for HF events were 1.09 (95% confidence interval [CI], 1.03-1.15) and 1.59 (95% CI, 1.49-1.70) for trace proteinuria and positive proteinuria vs. negative proteinuria, respectively. This association was present irrespective of clinical characteristics. A stepwise increase in the risk of myocardial infarction, stroke, and atrial fibrillation with proteinuria category was also observed. Our primary results were confirmed in participants after multiple imputation for missing values and in those having no medications for hypertension, diabetes mellitus, and dyslipidemia. Discriminative predictive value for HF events improved by adding the results of urine dipstick test to traditional risk factors (net reclassification improvement 0.0497, 95% CI 0.0346-0.0648, p < 0.001). Conclusions Not only positive proteinuria but also trace proteinuria was associated with a greater incidence of HF in the general population. Semiquantitative assessment of proteinuria would be informative for the risk stratification of HF.

AbstractWe aimed to clarify the association between restfulness from sleep and subsequent risk of cardiovascular disease (CVD). Medical records of 1,980,476 individuals with neither prior history of CVD nor sleep disorders were extracted from the Japan Medical Data Center. Restfulness from sleep was subjectively assessed using information from the questionnaires at initial health check-ups. The mean age was 45 ± 11 years and 1,184,937 individuals were men. Overall, 1,197,720 individuals (60.5%) reported having good restfulness from sleep. The mean follow-up period was 1122 ± 827 days. Myocardial infarction, angina pectoris, stroke, heart failure, and atrial fibrillation occurred in 3673 (0.2%), 30,241 (1.5%), 13,546 (0.7%), 28,296 (1.4%), and 8116 (0.4%) individuals, respectively. Multivariable Cox regression analyses including age, sex, and other CVD risk factors after multiple imputation for missing values showed that good restfulness from sleep was associated with lower incidence of myocardial infarction (hazard ratio [HR] 0.89, 95% confidence interval [CI] 0.83–0.95), angina pectoris (HR 0.85, 95% CI 0.83–0.87), stroke (HR 0.85, 95% CI 0.82–0.88), heart failure (HR 0.86, 95% CI 0.84–0.88), and atrial fibrillation (HR 0.93, 95% CI 0.89–0.97). The association of restfulness from sleep with CVD events was pronounced in subjects with younger age and female sex. In conclusion, good restfulness from sleep may be associated with the lower risk of myocardial infarction, angina pectoris, stroke, heart failure, and atrial fibrillation. Further studies are required to clarify the underlying mechanism and to develop a novel preventive approach for CVD from the perspective of sleep.

BackgroundAtrial fibrillation (AF), the most common sustained arrhythmia in CKD, is associated with poor clinical outcomes in both patients without CKD and patients with dialysis-treated ESRD. However, less is known about AF-associated outcomes in patients with CKD who do not require dialysis.MethodsTo prospectively examine the association of new-onset AF with subsequent risks of cardiovascular disease events and death among adults with CKD, we studied participants enrolled in the Chronic Renal Insufficiency Cohort Study who did not have AF at baseline. Outcomes included heart failure, myocardial infarction, stroke, and death occurring after diagnosis of AF. We used Cox regression models and marginal structural models to examine the association of incident AF with subsequent risk of cardiovascular disease events and death, adjusting for patient characteristics, laboratory values, and medication use.ResultsAmong 3080 participants, 323 (10.5%) developed incident AF during a mean 6.1 years of follow-up. Compared with participants who did not develop AF, those who did had higher adjusted rates of heart failure (hazard ratio [HR], 5.17; 95% confidence interval [95% CI], 3.89 to 6.87), myocardial infarction (HR, 3.64; 95% CI, 2.50 to 5.31), stroke (HR, 2.66; 95% CI, 1.50 to 4.74), and death (HR, 3.30; 95% CI, 2.65 to 4.12). These associations remained robust with additional adjustment for biomarkers of inflammation, cardiac stress, and mineral metabolism; left ventricular mass; ejection fraction; and left atrial diameter.ConclusionsIncident AF is independently associated with two- to five-fold increased rates of developing subsequent heart failure, myocardial infarction, stroke, or death in adults with CKD. These findings have important implications for cardiovascular risk reduction.

ObjectiveTo investigate the relationship of hospital admissions due to unexplained syncope and orthostatic hypotension (OH) with subsequent cardiovascular events and mortality.MethodsWe analysed a population-based prospective cohort of 30 528 middle-aged individuals (age 58±8 years; males, 40%). Adjusted Cox regression models were applied to assess the impact of unexplained syncope/OH hospitalisations on cardiovascular events and mortality, excluding subjects with prevalent cardiovascular disease.ResultsAfter a median follow-up of 15±4 years, 524 (1.7%) and 504 (1.7%) participants were hospitalised for syncope or OH, respectively, yielding 1.2 hospital admissions per 1000 person-years for each diagnosis. Syncope hospitalisations increased with age (HR, per 1 year: 1.07, 95% CI 1.05 to 1.09), higher systolic blood pressure (HR, per 10 mm Hg: 1.06, 95% CI 1.01 to 1.12), antihypertensive treatment (HR: 1.26, 95% CI 1.00 to 1.59), use of diuretics (HR: 1.77, 95% CI 1.31 to 2.38) and prevalent cardiovascular disease (HR: 1.59, 95% CI 1.14 to 2.23), whereas OH hospitalisations increased with age (HR: 1.11, 95% CI 1.08 to 1.12) and prevalent diabetes (HR: 1.82, 95% CI 1.23 to 2.70). After exclusion of 1399 patients with prevalent cardiovascular disease, a total of 473/464 patients were hospitalised for unexplained syncope/OH before any cardiovascular event. Hospitalisation for unexplained syncope predicted coronary events (HR: 1.85, 95% CI 1.49 to 2.30), heart failure (HR: 2.24, 95% CI 1.65 to 3.04), atrial fibrillation (HR: 1.84, 95% CI 1.50 to 2.26), aortic valve stenosis (HR: 2.06, 95% CI 1.28 to 3.32), all-cause mortality (HR: 1.22, 95% CI 1.09 to 1.37) and cardiovascular death (HR: 1.72, 95% CI 1.23 to 2.42). OH-hospitalisation predicted stroke (HR: 1.66, 95% CI 1.24 to 2.23), heart failure (HR: 1.78, 95% CI 1.21 to 2.62), atrial fibrillation (HR: 1.89, 95% CI 1.48 to 2.41) and all-cause mortality (HR: 1.14, 95% CI 1.01 to 1.30).ConclusionsPatients discharged with the diagnosis of unexplained syncope or OH show higher incidence of cardiovascular disease and mortality with only partial overlap between these two conditions.

Introduction: Although albuminuria evaluated with urinary albumin-to-creatinine ratio (UACR) was shown to be a prognostic marker in patients with heart failure, measurement of UACR needs special equipment. Urine dipstick test is a simple and convenient method which is available even in community-based health care. Hypothesis: We hypothesized that dipstick proteinuria might be a prognosticator in HFpEF. Methods: We assessed 738 discharged-alive patients in the PURSUIT-HFpEF registry. Patients received urine dipstick test, and were divided into 2 groups according to the absence or presence of proteinuria (proteinuria trace or more). The study endpoint was a composite of all-cause mortality and HF hospitalization. Results: Median age was 82 years and 410 patients were female. Four hundred thirty-four patients: proteinuria-(group 1); 304 patients: proteinuria+(group 2). Group 2 was more likely male with higher frequency of diabetes, previous myocardial infarction and chronic kidney disease, but less likely to take ACEIs than group 1. Higher blood pressure, NT-proBNP, creatinine, E/e’, TRPG, and LV mass index were observed in group 2 than group 1. The composite endpoint and HF hospitalization occurred more often in group 2 than group 1 (HR: 1.43, 95%CI: 1.09-1.87, log-rank P=0.009; HR: 1.57, 95%CI: 1.14-2.15, log-rank P=0.005, respectively); but all-cause mortality did not (HR: 1.40, 95%CI: 0.92-2.11, log-rank P=0.113). Multivariable Cox regression adjusting for NT-proBNP, eGFR and other major confounding factors showed that proteinuria was associated with the composite endpoint (HR: 1.42, 95% CI: 1.05-1.94, P=0.026), and HF hospitalization (HR: 1.51, 95%CI: 1.04-2.18, P=0.030), but not with all-cause mortality (HR: 1.51, 95%CI:0.94-2.43, P=0.092). Conclusions: Dipstick proteinuria may be a prognostic marker in patients with HFpEF. Evaluation of proteinuria by urine dipstick test may be a simple but useful method for risk stratification in HFpEF.

ObjectiveThe semiquantitative urine dipstick test is a simple and convenient method that is available in the smallest community-based healthcare clinics. We sought to clarify the prognostic significance of dipstick proteinuria in patients with heart failure (HF) with preserved ejection fraction (HFpEF).DesignA Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with preserved Ejection Fraction (PURSUIT-HFpEF) registry.Participants and settingWe assessed 851 discharged-alive patients in the PURSUIT-HFpEF registry who were initially hospitalised due to an acute decompensated HFpEF (EF≥50%) and elevated N-terminal-pro-brain natriuretic peptide (≥400 ng/L) at Osaka University Hospital and other 30 affiliated hospitals in the Kansai region of Japan. Patients received a urine dipstick test, and were divided into two groups according to the absence or presence of proteinuria. A trace or more of dipstick proteinuria was defined as the presence of proteinuria.Main outcome measuresA composite of cardiac death or HF rehospitalisation.ResultsMedian age was 83 years and 473 patients (55.6%) were female. Five hundred and two patients (59%) were proteinuria (−) and 349 patients (41%) were proteinuria (+). The composite endpoint and HF rehospitalisation occurred more often in proteinuria (+) individuals than proteinuria (−) individuals (log-rank p=0.006 and p=0.007, respectively); but cardiac death did not (log-rank p=0.139). Multivariable Cox regression analysis showed that the presence of proteinuria was associated with the composite endpoint (HR: 1.47, 95% CI 1.07 to 2.01, p=0.016), and HF rehospitalisation (HR: 1.48, 95% CI 1.07 to 2.05, p=0.020), but not with cardiac death (HR: 1.52, 95% CI 0.83 to 2.76, p=0.172).ConclusionsDipstick proteinuria may be a prognostic marker in patients with HFpEF. Evaluation of proteinuria by a urine dipstick test may be a simple but useful method for risk stratification in HFpEF.UMIN-CTR IDUMIN000021831.

Due to the COVID-19 outbreak, management of patients with severe cardiovascular disease has become much more complicated. The paper describes first-hand experience of managing a COVID-19 patient with chronic heart failure secondary to myocardial infarction who died from sudden cardiac death. Mortality risk factors in COVID-19-associated cardiac patients are discussed. The authors describe a case of a female patient B., 67 years old, who was taken to the hospital by ambulance with a preliminary diagnosis of community-acquired right lower lobe pneumonia, respiratory failure (RF) II (SpO294%). Coronary heart disease (CHD). Athero-sclerotic and postinfarction (2019) cardiosclerosis. Permanent atrial fibrillation. Hypertension, stage III, grade 3, risk 4 (stroke, 2019). Heart failure (HF) II-A (NYHA class II). Rapid tests for the diagnosis of influenza A and B and detection of COVID-19 antibodies IgG and IgM were negative. From the patient’s history it was found out that over the last 2 months she was in a private medical rehabilitation center. Nine days before her hospitalization, her relatives took her home. According to them, the patient developed fever (37.5–38.4 °C) 4 days before hospitalization, she took paracetamol in her discretion. On admission, her body temperature was 37.5 °C. The patient was hospitalized to the triage department; on the day of hospitalization, her nasopharyngeal lavage was taken for real-time PCR (polymerase chain reaction) for COVID-19. During the hospital stay the patient’s condition stabilized. The next day after hospitalization, the maximum body temperature was within 37.0 °C, shortness of breath decreased, heart rate slowed, RF disappeared, room-air SpO2increased up to 96%. According to the results of echocardiography, the left ventricle (LV) pump function remained preserved (LV ejection fraction was 50%), LV cavities were slightly enlarged, and valvular pathology was characterized by moderate mitral and tricuspid insufficiency. The area of hypokinesia due to myocardial infarction was determined only in the apical segment of the lateral wall and was compensated due to moderate left ventricular hypertensive hypertrophy (left ventricular mass index 129 g/L2). R wave amplitude on the electrocardiography was preserved, which indicated relative compensation of the central hemodynamics of the patient B. On day 2 of hospitalization, the patient’s condition remained stable. The body temperature normalized, leg swelling disappeared, cough and shortness of breath decreased, physical activity significantly improved. The patient was examined by an infectious disease specialist. After receiving the COVID-19 test result (positive PCR test), it was agreed to transfer the patient to a coronavirus hospital for further treatment in the infectious department. However, the patient died suddenly. Final diagnosis: coronavirus disease. COVID-19. Community-acquired bilateral lower lobe pneumonia (viral). Respiratory failure (RF) – 0. CHD. Atherosclerotic and postinfarction (2019) cardiosclerosis. Permanent atrial fibrillation. Hypertension, stage III, grade 3, risk 4 (stroke, 2019). HF II-B. Since dissection was not performed, the exact cause of death is unknown. The article describes important aspects of diagnosis and treatment that can prevent mortality. The authors emphasize that prevention and control of infectious diseases should be prioritized at any time. Individual measures of diagnosis and treatment should be taken considering specific local epidemic situations.

AbstractBackgroundThe increase in soluble suppression of tumorigenicity 2 (sST2) both in the diagnosis and prognosis of heart failure is well established; however, existing data regarding sST2 values as the prognostic marker after myocardial infarction (MI) are limited and have been conflicting. This study aimed to assess the clinical significance of sST2 in predicting 1-year adverse cardiovascular (CV) events in MI patients.Materials and methodsIn this prospective study, 380 MI patients were included. Participants were grouped into low sST2 (n = 264, mean age: 60.0 ± 12.1 years) and high sST2 groups (n = 116, mean age: 60.5 ± 11.6 years), and all study populations were followed up for major adverse cardiovascular events (MACE) which are composed of CV mortality, target vessel revascularization (TVR), non-fatal reinfarction, stroke and heart failure.ResultsDuring a 12-month follow-up, 68 (17.8%) patients had MACE. CV mortality and heart failure were significantly higher in the high sST2 group compared to the low sST2 group (15.5% vs. 4.9%, p = 0.001 and 8.6% vs. 3.4% p = 0.032, respectively). Multivariate Cox regression analysis concluded that high serum sST2 independently predicted 1-year CV mortality [hazard ratio (HR) 2.263, 95% confidence interval (CI) 1.124–4.557, p = 0.022)]. Besides, older age, Killip class >1, left anterior descending (LAD) as the culprit artery and lower systolic blood pressure were the other independent risk factors for 1-year CV mortality.ConclusionsHigh sST2 levels are an important predictor of MACE, including CV mortality and heart failure in a 1-year follow-up period in MI patients.

Abstract Background There is a well-documented empirical relationship between lipoprotein (a) [Lp(a)] and cardiovascular disease (CVD); however, causal evidence, especially from the Chinese population, is lacking. Therefore, this study aims to estimate the causal association between variants in genes affecting Lp(a) concentrations and CVD in people of Han Chinese ethnicity. Methods Two-sample Mendelian randomization analysis was used to assess the causal effect of Lp(a) concentrations on the risk of CVD. Summary statistics for Lp(a) variants were obtained from 1256 individuals in the Cohort Study on Chronic Disease of Communities Natural Population in Beijing, Tianjin and Hebei. Data on associations between single-nucleotide polymorphisms (SNPs) and CVD were obtained from recently published genome-wide association studies. Results Thirteen SNPs associated with Lp(a) levels in the Han Chinese population were used as instrumental variables. Genetically elevated Lp(a) was inversely associated with the risk of atrial fibrillation [odds ratio (OR), 0.94; 95% confidence interval (95%CI), 0.901–0.987; P = 0.012)], the risk of arrhythmia (OR, 0.96; 95%CI, 0.941–0.990; P = 0.005), the left ventricular mass index (OR, 0.97; 95%CI, 0.949–1.000; P = 0.048), and the left ventricular internal dimension in diastole (OR, 0.97; 95%CI, 0.950–0.997; P = 0.028) according to the inverse-variance weighted method. No significant association was observed for congestive heart failure (OR, 0.99; 95% CI, 0.950–1.038; P = 0.766), ischemic stroke (OR, 1.01; 95%CI, 0.981–1.046; P = 0.422), and left ventricular internal dimension in systole (OR, 0.98; 95%CI, 0.960–1.009; P = 0.214). Conclusions This study provided evidence that genetically elevated Lp(a) was inversely associated with atrial fibrillation, arrhythmia, the left ventricular mass index and the left ventricular internal dimension in diastole, but not with congestive heart failure, ischemic stroke, and the left ventricular internal dimension in systole in the Han Chinese population. Further research is needed to identify the mechanism underlying these results and determine whether genetically elevated Lp(a) increases the risk of coronary heart disease or other CVD subtypes.

Abstract Background The association of heart failure (HF) with the prognosis of atrial fibrillation (AF) remains unclear. OBJECTIVES To assess all-cause mortality in patients following hospitalization with comorbid AF in relation to the presence of HF. Methods We performed a cross-sectional analysis of data from 977 patients discharged from the cardiology ward of a single tertiary center between 2015 and 2018 and followed for a median of 2 years. The association between HF and the primary endpoint of death from any cause was assessed using multivariable Cox regression. Results HF was documented in 505 (51.7%) of AF cases at discharge, including HFrEF (17.9%), HFmrEF (16.5%) and HFpEF (25.2%). A primary endpoint event occurred in 212 patients (42%) in the AF-HF group and in 86 patients (18.2%) in the AF-no HF group (adjusted hazard ratio [aHR] 2.27; 95% confidence interval [CI], 1.65 to 3.13; P<0.001). HF was associated with a higher risk of the composite secondary endpoint of death from any cause, AF or HF-specific hospitalization (aHR 1.69; 95% CI 1.32 to 2.16 p<0.001). The associations of HF with the primary and secondary endpoints were significant and similar for AF-HFrEF, AF-HFmrEF, AF-HFpEF. Conclusions HF was present in half of the patients discharged from the hospital with comorbid AF. The presence of HF on top of AF was independently associated with a significantly higher risk of all-cause mortality than did absence of HF, irrespective of HF subtype.
