Since the cause of acute angina pectoris is usually vasoconstricted due to a blockage, it is important to expose the vessels to as few damaging influences as possible. It is very important that the blood lipid values are within the normal range. This can be achieved by a fat-reduced diet or a Mediterranean diet.
Smoking is another factor that is very damaging to the blood vessels. Even those who have been smoking for years can reduce their risk of contracting the secondary diseases of smoking the sooner they start smoking. Of course you cannot reduce your risk to that of a non-smoker, but by avoiding further damage, an improvement can be achieved.
