You are comparing apples to oranges. The 60% blockage is in a coronary artery. If this causes part of the heart to become under perfused it can lead to arrhythmias although not likely with only 60% blocked. That would be considered mild to moderate
The blockage that kills with hypertrophic cardiomyopathy is blockage of the outflow tract of the left ventricle. The muscle literally becomes so thick that when the ventricle contracts it totally blocks any outflow. Think trying to empty a balloon with a knot in the neck. Tjisisthe primary way the cardiomyopathy kills- cardiac output drops to zero suddenly
Arrhythmias are generally a more favorable arrest. If seen in time and treated with defibrillation most arrhythmias are reversible. As I said in the last post not so with the hypertrophic cardiomyopathy. A very experienced team in a hospital that knows. The cause of the arrest still doesn’t have very good odds with that one. And on a sidewalk somewhere you don’t know the cause of arrest. You always assume arrhythmia because it is the most common and the most treatable
Sorry for the typos. Still not great at typing on the iPad!
Are they claiming that there was so much thickness that no blood could even get out of his heart?
