Hello, Thank you for your question. You must be commended in taking such a keen interest in your fiance s health. To answer your first question, alcohol has been shown to promote cardiovascular health when taken in moderate amounts. This means 1/2 of an alcoholic drink/day for a women and 1 drink/day for males. For whiskey this means drinking 1 shot (1.5 oz)/day. Drinking more than 1 shot per day is considered heavy alcohol use and that can lead to diabetes, hypertension and other illnesses that can worsen cardiac disease. There are two types of stents. Both the bare metal stent and drug eluting stents last in the patient s coronary artery for a life time. However this stent can get re-stenosed or blocked up again. This risk is greatest up to 12 months after having the stent inserted and it is therefore important to take the medication prescribed by your cardiologist to decrease this risk. Eating a lot of outside food can negatively affect his health. Most outside foods are high in saturated and trans fat which raises your bad cholesterol (LDL) and lowers your good cholesterol (HDL).Having a high LDL accelerates the formation of plaque in the arteries of the heart and over time this can lead to a heart attack. Lifestyle changes are very important in the treatment of cardiac disease. This includes a healthy diet, regular exercise, cessation of smoking and good social support. Having a good relationship with your cardiologist and taking your medication as prescribed is very important. I hope your questions have been answered and I wish you and your fiancé good health
