BackgroundPopulation-based coronary heart disease (CHD) studies have focused on myocardial infarction (MI) with limited data on trends across the spectrum of CHD. We investigated trends in hospitalisation rates for acute and chronic CHD subgroups in England and Australia from 1996 to 2013.MethodsCHD hospitalisations for individuals aged 35–84 years were identified from electronic hospital data from 1996 to 2013 for England and Australia and from the Oxford Region and Western Australia. CHD subgroups identified were acute coronary syndromes (ACS) (MI and unstable angina) and chronic CHD (stable angina and ‘other CHD’). We calculated age-standardised and age-specific rates and estimated annual changes (95% CI) from age-adjusted Poisson regression.ResultsFrom 1996 to 2013, there were 4.9 million CHD hospitalisations in England and 2.6 million in Australia (67% men). From 1996 to 2003, there was between-country variation in the direction of trends in ACS and chronic CHD hospitalisation rates (p<0.001). During 2004–2013, reductions in ACS hospitalisation rates were greater than for chronic CHD hospitalisation rates in both countries, with the largest subgroup declines in unstable angina (England: men: −7.1 %/year, 95% CI −7.2 to –7.0; women: −7.5 %/year, 95% CI −7.7 to –7.3; Australia: men: −8.5 %/year, 95% CI −8.6 to –8.4; women: −8.6 %/year, 95% CI −8.8 to –8.4). Other CHD rates increased in individuals aged 75–84 years in both countries. Chronic CHD comprised half of all CHD admissions, with the majority involving angiography or percutaneous coronary intervention.ConclusionsSince 2004, rates of all CHD subgroups have fallen, with greater declines in acute than chronic presentations. The slower declines and high proportion of chronic CHD admissions undergoing coronary procedures requires greater focus.

Objective: Antiplatelet therapy is recommended in patients with coronary heart disease (CHD) who had the percutaneous coronary intervention (PCI) procedure to reduce major adverse cardiovascular events (MACE). There has been a lack of population-based studies that showed the superior effectiveness of ticagrelor over clopidogrel and similar studies have not been conducted in Indonesia yet. The aim of the study was to investigate the effectiveness of ticagrelor compared to clopidogrel in reducing the risk of MACE in patients with CHD after PCI.Methods: A retrospective cohort study with 1-year follow-up was conducted. 361 patients consisted of 111 patients with ticagrelor exposure and 250 patients with clopidogrel exposure. The primary outcome was MACE, defined as a composite of repeat revascularization, myocardial infarction, or all-cause death. The association between antiplatelet exposure and the MACE was analyzed with Cox proportional hazard regression, adjusted for sex, age, comorbid, PCI procedures and concomitant therapy.Results: MACE occurred in 22.7% of the subjects. Clopidogrel had a significantly higher risk of MACE compared with ticagrelor (28.8%, vs 9.0%, hazard ratio (HR): 1.96 (95% CI 1.01 to 3.81, p=0.047). There were no significant differences in risk of repeat revascularization (20.40% vs 5.40%, HR: 2.32, 95% CI 0.99 to 5.42, p = 0.05), myocardial infarction (11.60% vs 3.60%, HR: 2.08, 95% CI, 0.73 to 5.93, p = 0.17), and death (1.60% vs 1.80%, HR: 0.77, 95% CI, 0.14 to 4.25, p = 0.77).Conclusion: Clopidogrel had a higher risk of MACE compared to clopidogrel in patients with CHD after PCI, but there were no significant differences in the risk of repeat revascularization, myocardial infarction, and all-cause death.

Antiplatelet therapy has proven efficacy in the management of atherothrombosis. Clopidogrel, a thienopyridine, is a potent antiplatelet agent that achieves its antiplatelet effects by inhibiting the binding of adenosine 5' diphosphate to its platelet receptor. Large clinical trials have demonstrated a role for clopidogrel in the management of symptomatic atherosclerosis, acute coronary syndromes, and patients undergoing percutaneous coronary intervention. In this review, we discuss the pharmacology of clopidogrel including the mechanism of action, review the major clinical trials that have defined the current role of clopidogrel in coronary heart disease and percutaneous coronary intervention, and, finally, examine the concept of clopidogrel resistance and its potential clinical implications.

The Mehran risk score (MRS) was used to classify patients with coronary heart disease and evaluate the preventive effect of alprostadil on contrast-induced nephropathy (CIN) after percutaneous coronary intervention. The patients (n = 1146) were randomized into an alprostadil and control group and then divided into 3 groups on the basis of the MRS: low-risk, moderate-risk, and high-risk groups. The primary end point was the occurrence of CIN (alprostadil + hydration vs simple hydration treatment); secondary end points included serum creatinine, blood urea nitrogen, creatinine clearance rate, cystatin C, interleukin-6, C-reactive protein, proteinuria, and differences in the incidence of major adverse events. In the low-risk, moderate-risk, and high-risk groups, the incidence of CIN in the control and alprostadil group was 2.9 versus 2.6% ( P = .832), 11.4 versus 4.9% ( P = .030), 19.1 versus 7.7% ( P = .041), respectively. Multivariate logistic regression analysis showed that alprostadil treatment was a favorable protective factor for moderate-risk and high-risk CIN patients (OR = 0.343, 95% CI: 0.124-0.951, P = .040). Alprostadil can be used as a preventive treatment for moderate- and high-risk CIN patients classified by the MRS. The reduction of CIN by alprostadil may be related to an anti-inflammatory effect.

Background. Coronary heart disease (CHD) is caused by the blockage or spasm of coronary arteries. Evidence shows that liver disease is related to CHD. However, the correlation between the Model for End-Stage Liver Disease (MELD) score and outcomes in patients after percutaneous coronary intervention (PCI) was unclear. Method. A retrospective cohort study involved 5373 patients with coronary heart disease after PCI was conducted from January 2008 to December 2016. Participants were classified to four groups according to the MELD score by quartiles. The primary endpoint was long-term mortality including all-case mortality (ACM) and cardiac mortality (CM). Secondary endpoints included bleeding events, readmission, major adverse cardiovascular events (MACE), major adverse cardiovascular, and cerebrovascular events (MACCE). The longest follow-up time was almost 10 years. Results. There were significant differences in the incidences of ACM ( p = 0.038 ) and CM ( p = 0.027 ) among the four MELD groups, but there was no significant difference in MACEs ( p = 0.496 ), MACCEs ( p = 0.234 ), readmission ( p = 0.684 ), and bleeding events ( p = 0.232 ). After adjusting the age, gender, smoking, drinking status, and diabetes by a multivariable Cox regression analysis, MELD remains independently associated with ACM (HR:1.57, 95%CI 1.052–2.354, p = 0.027 ) and CM (HR:1.434, 95% CI 1.003–2.050, p = 0.048 ). Conclusion. This study indicated that the MELD score had a strong prediction for long-term mortality in CHD patients who underwent PCI.

Purpose: N-terminal fragment of the B type-natriuretic peptide (NT-proBNP) is an established tool for assessing acute dyspnoea and stratifying risk in heart failure, acute coronary syndromes (ACS), and stable coronary heart disease (SCHD). The aim of this study was to determine the value of NT-proBNP in predicting long-term risk of patients (Pts) submitted to elective percutaneous coronary intervention (PCI) in the setting of SCHD. Methods: We prospectively studied 291 Pts (age 64.3±9.6 years, 64 female) with SCHD submitted to successful elective PCI, and determined NT-proBNP immediately before PCI. Pts were divided into 2 groups according to NT-proBNP level: group T3 formed by Pts with NT-proBNP level in the highest tertile and group T1+T2 formed by all remaining Pts. The study endpoint was time to the first occurrence of death (D) or non-fatal myocardial infarction (MI) during the mean follow-up of 568 ± 322 days. Multivariable analyses were performed to adjust the prognostic value of NT-proBNP for the effects of factors known to influence NT-proBNP (age, gender, renal function, body mass index) and of other potential predictors of outcome (cardiovascular risk factors, prior cardiovascular events, left ventricular ejection fraction, and PCI characteristics). Results: NT-proBNP ranged from 5 pg/ml to 104 pg/ml in the 1st tertile (T1), 105 pg/ml to 358 pg/ml in the 2nd tertile (T2), and 364 pg/ml to 33.991 pg/ml in the 3rd tertile (T3). During follow-up, 8 Pts died and 11 suffered a non-fatal MI. NT-proBNP was significantly higher in Pts who experienced an adverse outcome (440 pg/ml [inter-quartile range, 104 –1712] vs 174 pg/ml [inter-quartile range, 78 – 460) in Pts with uneventful follow-up; P= 0.007). An NT-proBNP level ≥364 pg/ml was associated with a higher endpoint rate (13.4% vs 3.1% in group T1+T2) and independently predicted outcome: adjusted hazard ratio 3.11, 95% CI, 1.15– 8.37, P=0.025. The sensitivity, specificity, predictive positive value, and negative predictive value for the criterion NT-proBNP ≥364 pg/ml were 68.4%, 69.1%, 13.4%, and 96.9%, respectively. Conclusion: In the setting of SCHD, the level of NT-proBNP is a powerful prognostic marker even after successful PCI.
