Overview

Common risk factors related to underlying coronary artery disease (CAD) and inherited causes in the development of sudden cardiac arrest (SCA) are hypertension, male gender ,diabetes mellitus, hyperlipidemia, obesity, smoking, older age, obstructive sleep apnea (OSA) due to hypoxia, early ventricular fibrillation (VF) (within 48 hours of ACS increasing in-hospital mortality five times), early repolarization patten in early phase of myocardial infarction (MI), and family history of sudden death.

Risk Factors

• Common risk factors related to underlying coronary artery disease and inherited causes in the development of SCA are:

• Hypertension
• Male gender
• Diabetes mellitus
• Hyperlipidemia
• Obesity
• Smoking
• Older age
• Obstructive sleep apnea due to hypoxia
• Early VF (within 48 hours of ACS increasing in-hospital mortality five times)
• Early repolarization patten in early phase of MI
• Family history of premature death (sudden and unexpected) before age 50 attributed to heart disease in > 1 relative, presence of heart disease in close relative less than age 50, presence of ion channelopathies in family members
