question: My husband (age 60, 2 generation paternal cardiac history, regular medical care including ekg s, but not medicated for high blood pressure or cholesterol) suffered a 90% blockage in his Left Anterior Descending Artery and blockage in the diagonal. The cardiologist says he probably had a 40% blockage and an unstable plaque event brought on a sudden major blockage. Excellent care avoided the big one but he suffered a procedural heart attack when the diagonal collapsed as a stent was put in place in the LAD. 1. Please clarify how the diagonal may have been lost. 2.Could one regain that 10% lost function? 3. What could be ongoing consequences? 4. Is his risk of another event now elevated? Thank you very much.
