Impact of Self-Reported Family History of Premature Cardiovascular Disease on the Outcomes of Patients Hospitalized for Acute Coronary Syndrome (from the Acute Coronary Syndrome Israel Survey [ACSIS] 2000 to 2013)

Family history of premature cardiovascular disease (FHpCVD) is a well-established risk factor for development of coronary artery disease. However, little is known about the impact of FHpCVD on the outcome of patients presenting with acute coronary syndrome (ACS). We therefore aimed to evaluate the outcomes of ACS patients grouped by the presence and/or absence of FHpCVD. All patients ≤65 at admission who had an ACS event and were enrolled in the national ACS Israel Survey registry from 2000 to 2013 were included. Patients were grouped by the presence or absence of self-reported FHpCVD. Nearest neighbor propensity score matching was applied to create an evenly matched cohort of patients. Outcomes included 30-day MACE (defined as the composite of death, unstable angina pectoris, myocardial infarction, stroke, stent thrombosis, and urgent revascularization) and its individual components. Of 7,173 ACS patients, 33.9% reported FHpCVD. These patients were younger, with lower prevalence of diabetes, previous cerebrovascular and kidney diseases, but had higher prevalence of smoking and hyperlipidemia (p
