Regional differences in presentation characteristics, use of treatments and outcome of patients with cardiogenic shock: Results from multicenter, international registry.

BACKGROUND: Concurrent evidence about cardiogenic shock (CS) characteristics, treatment and outcome does not represent a global spectrum of patients and is therefore limited. The aim of this study was to investigate these regional differences. METHODS: To investigate regional differences in presentation characteristics, treatments and outcomes of patients treated with all types of cardiogenic shock (CS) in a single calendar year on a multi-national level. Consecutive patients from 19 tertiary care hospitals in 13 countries with CS who were treated between January 1, 2018 and December 31, 2018 were enrolled in this study. RESULTS: In total, 699 cardiogenic shock patients were included in this study. Of these patients, 440 patients (63%) were treated in European hospitals and 259 (37%) were treated in Non-European hospitals. Female patients (P<0.01) and patients with a previous myocardial infarction (P=0.02) were more likely to present at Non-European hospitals; whereas older patients (P=0.01) and patients with cardiogenic shock due to acute heart failure (P<0.01) were more likely to present at European hospitals. Vasopressor use was more likely in Non-European hospitals (P=0.04), whereas use of mechanical circulatory support (MCS) was more likely in European hospitals (P<0.01). Despite adjustment for relevant confounders, 30-day in-hospital mortality risk was comparably high in CS patients treated in European vs. Non-European hospitals (hazard ratio 1.08, 95% CI 0.84-1.39, P=0.56). CONCLUSION: Despite marked heterogeneity in characteristics and treatment of CS patients, including fewer use of MCS but more frequent use of vasopressors in Non-European hospitals, 30-day in-hospital mortality did not differ between regions.

The pattern of risk-factor profile in Egyptian patients with acute coronary syndrome: phase II of the Egyptian cross-sectional CardioRisk project.

BACKGROUND: Egypt is the most populous country in the Middle East and North Africa and has more than 15% of the cardiovascular deaths in the region, but little is known about the prevalence of traditional risk factors and treatment strategies in acute coronary syndrome (ACS) patients across Egypt. METHODS: From November 2015 to August 2017, data were collected from 1 681 patients with ACS in 30 coronary care centres, covering 11 governorates across Egypt, spanning the Mediterranean coast, Nile Delta and Upper Egypt, with a focus on risk factors and management strategies. RESULTS: Women constituted 25% of the patients. Premature ACS was common, with 43% of men aged less than 55 years, and 67% of women under 65 years. Most men had ST-elevation myocardial infarction (STEMI) (49%), while a larger percentage of women had unstable angina and non-ST-elevation myocardial infarction (NSTEMI) (32% each; p < 0.001). Central obesity was present in 80% of men and 89% of women, with 32% of men and women having atherogenic dyslipidaemia. Current smoking was reported by 62% of men and by 72% of men under 55 years. A larger proportion of women had type 2 diabetes (53 vs 34% of men), hypertension (69 vs 49%), dyslipidaemia, and obesity (71 vs 41%) (p < 0.001 for all). There were no gender differences in most diagnostic and therapeutic procedures, but among STEMI patients, 51% of men underwent primary percutaneous coronary intervention compared to 46% of women (p = 0.064). CONCLUSIONS: Central obesity and smoking are extremely prevalent in Egypt, contributing to an increased burden of premature ACS, which warrants tailored prevention strategies. The recognised tendency worldwide to treat men more aggressively was less pronounced than expected.
