Smoking and Heart Disease

Jul 22, 2017

All the following are true about smoking and heart disease EXCEPT:


Answer: B.  Male smokers are 25% more likely to develop coronary heart disease than female smokers.

Explanation: According to a meta-analysis, female smokers are actually 25% more likely to develop coronary heart disease than male smokers. Female sex has also been linked to a higher rate of adverse events after acute coronary syndrome. The remaining statements are all true. The incidence of MI is increased 6-fold in women who smoke at least 20 cigarettes per day. HDL cholesterol increases quickly within 3 wks of smoking cessation, but there is no clear change in cholesterol levels after that point. Interestingly, smokers who take a thrombolytic agent for acute MI tend to have better outcomes than nonsmokers, an occurrence known as the "smoker’s paradox."
