Medications

Research continues to suggest that aggressive cholesterol-lowering treatment with statins can help prevent heart attacks and sudden death from heart disease. An important 2006 study found that high-dose statin treatment may even have the potential to reverse coronary artery disease.

Side effects of statins may include stomach upset, headaches, skin rashes, muscle aches, sexual dysfunction, drowsiness, dizziness, nausea, constipation, and peripheral neuropathy (numbness or tingling in the hands and feet).

The main safety concern with statins is an uncommon condition called myopathy, which can cause muscle and joint pain and possible muscle damage. Doctors will immediately stop statin therapy if myopathy occurs. Patients should talk to their doctor about any unusual muscle discomfort or weakness or if their urine becomes brown-colored. Statins can also affect the liver, particularly at higher doses, so patients taking these drugs should receive regular liver function tests.

Angiotensin Converting Enzyme Inhibitors

Angiotensin converting enzyme (ACE) inhibitors are important drugs for treating patients who have had a heart attack, particularly for patients at risk for heart failure. These drugs are commonly used to treat hypertension and are recommended as first-line treatment for people with diabetes and kidney damage.

ACE inhibitors include captopril (Capoten), ramipril (Altace), enalapril (Vasotec), quinapril (Accupril), benazepril (Lotensin), perindopril (Aceon), and lisinopril (Prinivil, Zestril).

Side Effects. Side effects of ACE inhibitors are uncommon but may include an irritating cough, excessive drops in blood pressure, and allergic reactions. In the past, doctors sometimes avoided giving aspirin to patients who were taking ACE inhibitors because the combination was believed to cause kidney problems. But, a 2005 study of patients with both coronary artery disease and heart failure found that taking aspirin and ACE inhibitor together is safe.

Magnesium

Magnesium has blood-thinning properties and may help open blood vessels. It is important to correct any magnesium deficiencies in patients (such as those who are taking diuretics).

Infection-Fighting Medications

Flu Shots. Influenza vaccinations may help protect patients against another heart attack during flu season.

Antibiotics. Researchers have investigated antibiotics for treating patients with heart disease and past infection of the bacteria Chlamydia pneumoniae. Results from several recent large-scale clinical trials, published in 2003 in the Journal of the American Medical Association (JAMA) and presented in 2004 at the European Society of Cardiology annual meeting, suggest that antibiotic treatment provides no benefit in preventing heart attack or other cardiac events in patients with coronary artery disease. While it is still possible that C. pneumoniae may play a role in triggering inflammatory responses associated with ACS, antibiotic therapy is no longer considered appropriate for treatment or prevention of heart disease.
