Unstable Angina

When the chest pain occurs at rest or mild exertion, it is known as unstable angina. The most common underlying condition is coronary artery disease due to atherosclerosis. The plaque build-up in the arterial walls causes narrowing and rigidity, thereby decreasing the blood flow to the heart. Smoking, diabetes, hypertension, old age, male gender, sedentary lifestyle, obesity, high cholesterol levels, etc., are some risk factors. Symptoms include squeezing or crushing pain in the chest radiating to the left shoulder and hand, sweating, and breathlessness. Angioplasty, surgeries, and medications help. Regular exercise, reducing weight, eating healthy, and stopping smoking and alcoholism can prevent angina.
