GLP-1s and Preventative Cardiology

Dr. Ambreen Mohamed

A patient in his mid 50s came to see us with a story we hear far too often. He has a history of obesity, high blood pressure, obstructive sleep apnea, and established coronary artery disease after a prior heart attack. He was taking his medications, trying to eat better, and knew he needed to exercise more. But every attempt at weight loss seemed to end the same way. He would lose a few pounds, plateau, become discouraged, and regain the weight. His blood pressure remained difficult to control. He was constantly fatigued. His sleep apnea was severe enough to require CPAP, and even walking longer distances left him short of breath.

Obesity isn’t simply a matter of willpower. It is a chronic disease driven by complex hormonal, metabolic, and environmental factors. Treating it like any other chronic medical condition often leads to better outcomes. After discussing risks, benefits, and expectations, we started a GLP-1 receptor agonist alongside continued lifestyle changes and aggressive management of his cardiovascular risk factors.

Over the following few months we saw some amazing results:

  • He lost over 20 pounds
  •  His blood pressure improved enough that we were able to reduce one of his antihypertensive medication
  • His energy improved dramatically
  • His CPAP pressures were lowered after repeat sleep evaluation
  • He became physically active again, eventually walking an average of 2 miles most days

As cardiologists, we often focus on cholesterol numbers, blood pressure targets, and imaging results and yes, those remain critically important. But sometimes one intervention changes multiple cardiovascular risk factors simultaneously. 

Clinical trials such as the SELECT trial have demonstrated that GLP-1 receptor agonists can reduce major adverse cardiovascular events in people with overweight or obesity and established cardiovascular disease, even in those without diabetes.

That doesn’t mean these medications are for everyone. Lifestyle remains the foundation. Nutrition, physical activity, sleep, stress management, and appropriate medications all work together, not against one another.

The goal isn’t simply weight loss, it’s reducing cardiovascular risk, improving quality of life, and helping patients live longer, healthier lives.
