Yes: Severe hyperkalemia can lead to cardiac arrest, but not myocardial infarction (blockage of the heart arteries). It is highly lethal when it is very elevated and causes characteristic changes on EKG. It may be caused by undiagnosed kidney failure. It can be readily treated in an ER.

Yes: High potassium, (hyperkalemia) causes the heart to slow dangerously and will eventually cause ventricular dysrhythmia. The heart just stops. This is not the classic "heart attack" caused by atherosclerosis, but the problem is just as serious if not worse.
