Heart disease and mental health are closely connected, each influencing the other in significant ways. Chronic stress, anxiety, and depression can increase the risk of heart disease by raising blood pressure, affecting sleep, and encouraging unhealthy behaviors like smoking or poor diet. After a cardiac event, many patients experience emotional challenges that may slow recovery or reduce motivation to follow treatment plans. Mental health conditions can also affect how the body handles inflammation and stress hormones, further impacting heart function. Recognizing this link encourages early support, healthy coping strategies, and integrated care to improve both emotional well-being and heart health.
