Sudden Cardiac Death (SCD) Overview

Flashcards covering key terms and concepts related to Sudden Cardiac Death (SCD), its epidemiology, pathophysiology, and prevention strategies.

Sudden Cardiac Death (SCD)

The unexpected cessation of heart function due to an electrical malfunction, leading to death within one hour of symptom onset.

Disability-Adjusted Life Years (DALYs)

A measure of overall disease burden, expressed as the number of years lost due to ill-health, disability, or early death.

Sudden Cardiac Death (SCD)

Disability-Adjusted Life Years (DALYs)

A measure of overall disease burden, expressed as the number of years lost due to ill-health, disability, or early death.

Epidemiological Trends

Patterns and changes in the incidence of health-related events in specific populations over time.

Primary Prevention

Strategies aimed at preventing the occurrence of disease through risk management and lifestyle changes.

Ventricular Fibrillation

A life-threatening heart rhythm that results in a rapid, uncoordinated contraction of the heart's ventricles.

Coronary Artery Disease (CAD)

A condition characterized by the narrowing or blockage of the coronary arteries, usually caused by atherosclerosis.

Myocardial Ischemia

A condition in which blood flow to the heart muscle is reduced, preventing it from receiving enough oxygen.

Hypertrophic Cardiomyopathy (HCM)

A disease characterized by the thickening of the heart muscle, which can lead to sudden cardiac death.

Implantable Cardioverter Defibrillator (ICD)

A device implanted in patients at risk of sudden cardiac death that monitors heart rhythms and delivers shocks if necessary.

Socioeconomic Disparities

Differences in economic status and access to resources that can affect health outcomes in different populations.

Arrhythmias

Abnormal heart rhythms that can lead to serious complications, including sudden cardiac death.
