Could skipping meds lead to a second heart attack?

Many heart patients aren’t taking their medicine. Are they at greater risk for another heart attack?

Imagine: the shortness of breath and the occasional chest pain you’ve been feeling intensifies. You’re rushed to the emergency room where doctors decide you need bypass surgery to survive.

Then, following surgery, your cardiologist prescribes five medications you’ve never taken before. You feel brain-fogged, exhausted, achy and depressed. Is it part of the recovery process or the new drugs? Do you have to take all those pills?

Results of a study published by the American College of Cardiology show that proper medication can reduce the incidence of a second heart attack or stroke by 50 percent. But researchers who conducted that study at the Cardiovascular Institute at Mount Sinai in New York found less than half – just 43 percent –followed their medication plans in the year following their heart attacks.

“I don’t think we as physicians do a very good job at clearly explaining to our patients exactly what the role of a medication is,” said Dr. S. Hinan Ahmed, an interventional cardiologist at San Antonio’s University Hospital and an associate professor of cardiology at UT Health.

Dr. Ahmed believes a lack of knowledge about a drug and the fact that it may be costly are the two greatest barriers to ensuring patients comply with their medication plans.

Among the frequently prescribed classes of heart medications that raise patient concern are beta-blockers and statins.

Beta –blockers are used to lower blood pressure and improve blood flow by blocking the effects of adrenaline which increases in stressful situations. Side effects may include depression, breathing problems and dizziness.

Statins help your liver remove cholesterol that may damage your heart. They’ve been linked to cases of severe muscle damage, liver problems and the development of diabetes.

Dr. Ahmed says, however, severe side effects are rare, and statins and beta-blockers are generally so effective patients should give them a try while being alert for any problems.

Finding the right combination of meds isn’t an exact science. Recent research published in the Annals of Internal Medicine found that a significant number of heart patients are not being properly assessed and are probably taking too much or too little medication.

Dr. Ahmed says many cardiologists use the American College of Cardiology guidelines for determining which heart meds to prescribe.

He stresses the need for good doctor-patient communication:

  • If you are taking medicine for several conditions –for example, heart disease, diabetes, and acid reflex–ask your primary care doctor to look at the complete list for how they might interact. Also discuss the medications with your cardiologist and members of your medical team addressing your specific health conditions.
  • Take all your medications, or a complete list of them, to your appointments.
  • Keep a written log of any side effects and when they occurred.
  • Don’t stop taking a medication without your doctor’s supervision.
