Stenting treats a symptom. This guide explains the disease.

The most common misconception in cardiology: that having a stent placed cured the heart disease. It opened one blocked artery. The underlying atherosclerotic process — the decades of plaque building throughout every coronary artery — continues unless it is aggressively medically managed.

This guide explains CAD as a chronic disease process, the full diagnostic toolkit used to assess it, and the evidence-based framework for determining when medication is sufficient vs. when a procedure is genuinely needed.

“A stent is not a cure. It is a plumbing fix for one artery. The disease is everywhere, and the only thing that slows it down in every artery simultaneously is aggressive medical therapy — statins, blood pressure control, antiplatelet therapy, lifestyle. That is the conversation I want every CAD patient to understand.”

Common Questions

My stress test was positive. Does that mean I need a stent?
Not necessarily. A positive stress test indicates ischemia — reduced blood flow to some area of the heart during stress. Depending on the size of the affected territory, symptoms, and your overall anatomy, optimal medical therapy may be the preferred approach. The ISCHEMIA trial showed that in stable CAD with moderate ischemia, initial medical management is equally effective as upfront stenting for preventing death and MI. This is covered in detail in the guide.
What is a coronary calcium score and should I get one?
A coronary calcium score (CAC) uses a CT scan to quantify calcium deposits in coronary arteries — a surrogate for total plaque burden. A score of 0 means very low short-term risk; a score above 300 or in the 75th percentile for your age and sex indicates significantly elevated risk. CAC is most useful in "intermediate risk" patients to reclassify them as lower or higher risk, potentially changing the decision to start statin therapy. The guide covers who should consider it.
What is the difference between a STEMI and an NSTEMI?
Both are heart attacks (myocardial infarctions) caused by acute coronary occlusion. A STEMI (ST-elevation MI) involves complete artery occlusion with characteristic ECG changes — it requires immediate (within 90 minutes) emergency PCI (stenting). An NSTEMI (non-ST-elevation MI) involves partial occlusion with troponin elevation but no ST elevation — it requires urgent but not necessarily immediate intervention. Both require hospitalization and aggressive treatment.
