What is the most common cause of death in the elderly?
Short answer: The most common cause of death in older adults is cardiovascular disease, especially ischemic heart disease (heart attacks) and heart failure. Cerebrovascular disease (stroke) and other circulatory disorders are also leading contributors.
Explanation
Across high-income countries and globally, diseases of the heart and blood vessels are the leading cause of mortality among older adults. Age-related changes in arteries, long-term exposure to risk factors (hypertension, high cholesterol, diabetes, smoking, and physical inactivity), and cumulative plaque buildup (atherosclerosis) increase the likelihood of myocardial infarction, heart failure, and stroke. Comorbid conditions such as diabetes and chronic kidney disease further raise cardiovascular risk. While cancer, chronic respiratory disease, dementia (including Alzheimer disease), and infections are important causes of death in the elderly, cardiovascular disease remains the single largest category.
