It’s never too late to lower your risk of heart disease. The risk of heart disease rapidly decreases once you stop smoking.
In the first twenty four hours after quitting, your blood pressure
and pulse return to normal, as do the oxygen and carbon monoxide levels in your blood. This alone relieves some of the extra stress you
have been imposing on your heart.
Within three months after quitting, you will experience a sharpening
of the senses of taste and smell. Your circulation will be improved
and your lungs may work at up to 30 percent greater capacity.
After a year, your risk of CHD will be about halfway between a
smoker’s and a nonsmoker’s. Abnormality of blood clotting due to
a higher level of fibrinogen (a component of blood that makes blood clotting, possible) and platelets (particles in the blood that by aggregation
make the clots possible) related to smoking will disappear,
but it takes longer to undo the damage to the arteries. If your smoking
has contributed to plaque deposits in the coronary or other arteries,
the damage can only be mitigated with time and effort. Combining
proper food choices, exercise, and drugs if needed (and even
surgery in more extreme cases), you can slowly undo some of this
