Cardiac health refers to the overall well-being of the heart and blood vessels, which are vital for circulating oxygen-rich blood throughout the body. Common cardiac conditions include coronary artery disease, heart attack, heart failure, arrhythmias, and high blood pressure. These disorders often result from lifestyle factors such as poor diet, lack of exercise, smoking, stress, and underlying medical conditions like diabetes or high cholesterol. Symptoms may include chest pain, shortness of breath, fatigue, or palpitations. Maintaining cardiac health involves regular physical activity, a heart-healthy diet, avoiding tobacco, managing stress, and routine medical checkups to monitor blood pressure and cholesterol levels.
