English to Chinese Medical Medical: Cardiology cardiovascular diesease

Don't smoke. There are plenty of reasons to give up smoking, but start with the fact that it doubles your risk of having a heart attack. In fact, smoking speeds up or exacerbates just about every process that contributes to cardiovascular disease: It reduces blood flow through the arteries by making them even stiffer and narrower, raises blood pressure, contributes to the formation of plaques that can lead to clogs, makes it easier for blood to clot around {obstructions}, and worsens pain from peripheral vascular disease.
