Your Angiogram Was Clean. Nobody Tested Whether Your Artery Clamps.

Coronary artery spasm is diagnosed with an acetylcholine test in the cath lab, not an angiogram. What it measures, why it is rarely run, how drugs blunt it.

I Finally Have the Diagnosis That Explains Years of Chest Pressure. It Wasn't Anxiety. It Was Never "All in My Head."

A stent didn't stop the episodes. Every scan said fine. The answer came from the one test I almost turned down.

The Heart-Attack Risk Hiding in Your Immune Cells

Clonal hematopoiesis (CHIP): a blood mutation that roughly doubles coronary risk. No cardiology society screens for it. Why, and why I stopped chasing the test.

The Question No One Asked

A stent fixed my blockage. No cath-lab test could say whether a silent heart attack had already left a scar. Cardiac MRI can, and a stent doesn't rule it out.

The Heart Attacks You Never Feel

What happens when coronary plaque ruptures and heals instead of killing you: a silent wound that narrows the artery. It likely built my 80% blockage at 44.

The Battle for the Coronary Artery Scan That Saved My Life

ECG, echo, Holter, stress test: all normal. A coronary CT angiogram (CCTA) found an 80% blockage anyway. What it shows, and the exact words to ask for it.

I Aced Every Cardiac Test. I Still Had an 80% Blockage.

My ECG, echo and Holter all missed an 80% blockage. Only two tests see plaque in the artery: a calcium score and a CT angiogram (CCTA). Which one to ask for.

I Had an 80% Coronary Blockage at 44. Every Test Said I Was Fine.

Every test was normal at 44: ECG, echo, Holter. Then a CT angiogram found an 80 percent heart blockage. How serious that is, and the fight to get the scan.
