Leading Cardiologist Identifies Simple Lifestyle Change Halving Heart Disease Risk
New York, NY – October 14, 2025 – A prominent U.S.cardiologist is asserting that prioritizing consistent, quality sleep is the single most impactful action individuals can take to dramatically reduce their risk of heart disease. Dr. Michael Twyman, a leading expert in preventative cardiology at Mount Sinai Hospital, presented findings at the American Heart Association’s annual conference today, October 14, 2025, outlining a direct correlation between adequate sleep and a significant decrease in cardiovascular events.
Heart disease remains the leading cause of death globally, responsible for approximately 697,000 deaths in the United States alone in 2023, according to the Centers for Disease Control and Prevention. While factors like diet and exercise are widely recognized as crucial for heart health, Dr.Twyman’s research highlights sleep as a foundational element frequently enough overlooked. His team’s analysis of data from over 20,000 patients revealed that those consistently achieving 7-9 hours of sleep per night experienced a nearly 50% reduction in the incidence of heart attacks, strokes, and other major cardiovascular problems. The findings underscore a growing body of evidence suggesting that insufficient sleep disrupts vital bodily functions, contributing to inflammation, elevated blood pressure, and impaired glucose metabolism - all key drivers of heart disease. Further research is planned to investigate optimal sleep patterns for different demographics and to explore the potential for sleep-focused interventions as a core component of preventative cardiology.
