Does Myonit SR 2.6 Tablet stop heart attacks?

Myonit SR 2.6 Tablet is prescribed to prevent attacks of heart-related chest pain (angina) in patients with coronary artery disease. In this disease, the blood vessels (coronary arteries) that supply blood to the heart become narrowed, because of which the heart has to work harder to get enough oxygen. Myonit SR 2.6 Tablet prevents angina by relaxing the blood vessels so that the heart does not have to work very hard. Also, relaxation of the coronary arteries increases the oxygen supply to the heart.
