Background: This study was designed to measure levels of B-type natriuretic peptide (BNP) across entire spectrum of acute coronary syndrome (ACS) and to find its correlation with left ventricular functions and heart failure.Methods: We measured BNP levels at baseline in 100 consecutive patients between 24-96 hours after the onset of ischemic symptoms in patients of ACS. Echocardiography was performed in all patients between day 2-5 after the index diagnosis and stabilizing the patients.Results: The BNP levels were raised across the entire spectrum of ACS, with levels (>80 pg/ml) in 32.2% of patients with ST segment-elevation myocardial infarction (STEMI), in 24% with non-ST segment-elevation myocardial infarction (NSTEMI), and in 16.6% with unstable angina (UA) respectively. High BNP levels were associated with greater increase in LV end-systolic volumes (r=+0.545, p<0.001) (LVESV) and end-diastolic volumes (LVEDV) (r=+0.336, p<0.001). There was a negative correlation between BNP levels and left ventricular ejection fraction (LVEF) (r=-0.394, p<0.002). BNP levels were significantly raised (156.0±45.1 vs 57.7±18.3 pg/ml, p<0.02) in patients developing symptomatic clinical heart failure, irrespective of LVEF ≤40%.Conclusions: Integrated use of echocardiography and BNP levels provide powerful incremental assessment of cardiac functions, clinical status, and outcome across the entire spectrum of acute coronary syndromes (ACS). Increased BNP levels are associated with progressive ventricular dilatation, LV-dysfunction, development of clinical heart failure and is associated with poor prognosis in patients of ACS.

Over the last 50 years, the treatment of acute ST-segment elevation myocardial infarction (STEMI) has been considerably improved. The widespread implementation of reperfusion (initially pharmacological and later mechanical) resulted in a magnificent reduction in the rates of in-hospital mortality from about 25% in the 1970s to 5% in the late 2010s. Mortality in real life, however, is higher than these figures shown in clinical trials. There is compelling evidence showing the association between duration of ischaemia and mortality. This is the basis for the timely reperfusion in STEMI. All actions should be made to reduce all components of the ischaemic time. Despite these advances, STEMI survivors are still at high risk for developing repetitive events, including reinfarctions, heart failure, and sudden death. Evolving therapies beyond timely reperfusion are contributing to further reduce the morbidity associated with STEMI.

Estimates of the risk of recurrent cardiovascular events (residual risk) among patients with acute coronary syndromes have largely been based on clinical trial populations. Our objective was to estimate the residual risk associated with common comorbidities in a large, unselected, population-based cohort of acute coronary syndrome patients. 31,056 ACS patients (49.5%—non-ST segment elevation myocardial infarction [NSTEMI], 34.0%—ST segment elevation myocardial infarction [STEMI] and 16.5%—unstable angina [UA]) hospitalised in Alberta between April 2010 and March 2016 were included. The primary composite outcome was major adverse cardiovascular events (MACE) including: death, stroke or recurrent myocardial infarction. The secondary outcome was death from any cause. Cox-proportional hazard models were used to identify the impact of ACS type and commonly observed comorbidities (heart failure, hypertension, peripheral vascular disease, renal disease, cerebrovascular disease and diabetes). At 3.0 +/- 3.7 years, rates of MACE were highest in the NSTEMI population followed by STEMI and UA (3.58, 2.41 and 1.68 per 10,000 person years respectively). Mortality was also highest in the NSTEMI population followed by STEMI and UA (2.23, 1.38 and 0.95 per 10,000 person years respectively). Increased burden of comorbidities was associated with an increased risk of MACE, most prominently seen with heart failure (adjusted HR 1.83; 95% CI 1.73–1.93), renal disease (adjusted HR 1.52; 95% CI 1.40–1.65) and diabetes (adjusted HR 1.51; 95% CI 1.44–1.59). The cumulative presence of each of examined comorbidities was associated with an incremental increase in the rate of MACE ranging from 1.7 to 9.98 per 10,000 person years. Rates of secondary prevention medications at discharge were high including: statin (89.5%), angiotensin converting enzyme inhibitor/angiotensin receptor blocker (84.1%) and beta-blockers (85.9%). Residual cardiovascular risk following an acute coronary syndrome remains high despite advances in secondary prevention. A higher burden of comorbidities is associated with increased residual risk that may benefit from aggressive or novel therapies.

This chapter is aimed at junior hospital pharmacists and community pharmacists and is loosely based on the British National Formulary, Chapter 2. It covers diagnosis, symptoms, and treatment management plans for a variety of cardiovascular topics including hypertension, heart failure, and angina, and additional topics that cover issues related to anticoagulation, acute coronary syndromes, ST-segment elevation myocardial infarction, and cardiopulmonary resuscitation.

Abstract OBJECTIVES The aim of this was to analyse current outcomes in patients referred to coronary artery bypass grafting (CABG) for acute coronary syndromes (ACSs), including ST-elevation or non-ST-elevation ACS (non-ST-segment elevation myocardial infarction) or unstable angina. METHODS Patients (n = 2432) undergoing CABG for ACS between January 2010 and December 2017 were prospectively entered into a surgical myocardial infarction registry in North Rhine-Westphalia, Germany. Key end points were in-hospital all-cause mortality (IHM) and major adverse cardio-cerebral events (MACCE). Predictors for IHM and MACCE were analysed by multivariable logistic regression. RESULTS Patients (78% males) were referred for CABG for unstable angina (25%), non-ST-segment elevation myocardial infarction (50%), and ST-segment elevation myocardial infarction (25%). The mean patient age was 68 ± 11 years, logistic EuroSCORE was 19 ± 18% and three-vessel and left main stem diseases were diagnosed in 81% and 45% of patients, respectively. On-pump CABG with cardiac arrest or beating heart was performed in 92% and 2%, respectively, with only 6% off-pump surgery and 6% multiple arterial revascularization (3.1 ± 1.0 grafts, 93% left internal thoracic artery). Emergency CABG was performed in 23% of patients (42% in ST-segment elevation myocardial infarction; P &lt; 0.001). The total IHM and MACCE rates were 8.1% and 17.5% and were highest in ST-segment elevation myocardial infarction patients with 12.6% and 28.5%, respectively (P &lt; 0.001). Key predictors for IHM and MACCE were female gender, elevated troponin, left ventricular ejection fraction, inotropic support, logistic EuroSCORE, cardiopulmonary bypass and aortic clamp time and the need for emergency CABG. CONCLUSIONS Surgical myocardial revascularization in patients with ACS is still linked to substantial in-hospital mortality. Emergency CABG for patients with ACS was associated with poorer outcomes.
