Cardiovascular disorders (CVDs) describe a group of medical conditions that affect the heart and the network of blood vessels, including coronary heart disease, heart attacks, strokes, cardiac failure, and high blood pressure. These diseases are among the leading causes of death worldwide. Unhealthy habits such as poor diet, lack of physical activity, smoking, and heavy alcohol consumption are major contributors. Other factors that increase the risk include high cholesterol levels, diabetes, excess body weight, and genetic traits. Symptoms may include chest pain, difficulty breathing, fatigue, irregular heartbeats, and swelling in the legs or feet. Prevention mainly involves maintaining a healthy lifestyle, staying physically active, keeping a healthy weight, and avoiding tobacco use.
