Over one third of elderly patients with high-risk acute coronary syndrome are frail. Frailty phenotype is an important and independent prognostic marker in these patients.

Cardiovascular diseases are the leading cause of death in the world. Coronary artery diseases, atrial fibrillation or hypertensive heart disease, are among the most important cardiovascular disorders. Hypertension represents a significant risk factor for cardiovascular mortality; thus, control of high blood pressure has become a priority to prevent major complications. Although the choice of drugs for treating hypertension remains controversial, extensive clinical evidences point to calcium channel blockers as first-line agents. Diltiazem, a non-dihydropyridine calcium channel blocker, is an effective and safe antihypertensive drug, alone or in combination with other agents. Diltiazem lowers myocardial oxygen demand through a reduction in heart rate, blood pressure, and cardiac contractility, representing also a good alternative for the treatment of stable chronic angina. Furthermore, diltiazem reduces conduction in atrioventricular node, which is also useful for heart rate control in patients with atrial fibrillation. In this review, clinical experts highlight studies on diltiazem effectiveness and safety for the treatment of several cardiovascular diseases and make evidence-based recommendations regarding the management of diltiazem in the clinical practice.FundingLacer Spain.

Background In contrast with the setting of acute myocardial infarction, there are limited data regarding the impact of diabetes mellitus on clinical outcomes in contemporary cohorts of patients with chronic coronary syndromes. We aimed to investigate the prevalence and prognostic impact of diabetes according to geographical regions and ethnicity. Methods and results CLARIFY is an observational registry of patients with chronic coronary syndromes, enrolled across 45 countries in Europe, Asia, America, Middle East, Australia, and Africa in 2009–2010, and followed up yearly for 5 years. Chronic coronary syndromes were defined by ≥1 of the following criteria: prior myocardial infarction, evidence of coronary stenosis >50%, proven symptomatic myocardial ischaemia, or prior revascularization procedure. Among 32 694 patients, 9502 (29%) had diabetes, with a regional prevalence ranging from below 20% in Northern Europe to ∼60% in the Gulf countries. In a multivariable-adjusted Cox proportional hazards model, diabetes was associated with increased risks for the primary outcome (cardiovascular death, myocardial infarction, or stroke) with an adjusted hazard ratio of 1.28 (95% confidence interval 1.18, 1.39) and for all secondary outcomes (all-cause and cardiovascular mortality, myocardial infarction, stroke, heart failure, and coronary revascularization). Differences on outcomes according to geography and ethnicity were modest. Conclusion In patients with chronic coronary syndromes, diabetes is independently associated with mortality and cardiovascular events, including heart failure, which is not accounted by demographics, prior medical history, left ventricular ejection fraction, or use of secondary prevention medication. This is observed across multiple geographic regions and ethnicities, despite marked disparities in the prevalence of diabetes. ClinicalTrials identifier ISRCTN43070564
