My Uncle, a veteran diver since military trained in his teens some 40 years ago, recently suffered a heart attack (on land, unrelated to diving), and has since been told by his doctor to refrain from scuba diving. The doctor is not a diver, nor trained in the science of diving. Is this a good recommendation? I realize that a heart attack underwater could be a bad incident, but my question is: could any aspect of diving cause another heart attack? I'm referring to pressure, both air and water, or nitrogen in the bloodstream, not the sight of a shark or mermaid.
