Smoking

       For those who smoke, the most important thing is to quit smoking. Smoke increases the level of carbon dioxide in the blood, and it decreases oxygen. And as the arteries are clogged, heart desperately needs oxygen. And smoking, of course, is the worst thing that could ever be for the heart. Doctors remark, those who give up smoking reduce the chance to catch this disease. Moreover, cigarette smoke makes platelets stick together, compounding the process of blood clotting. Here is another fact that may make you quit smoking. Studies have shown that the mortality rate among patients with angina pectoris who stopped smoking 2 times lower than the mortality rate among those who continued to smoke.
