Serial determination of plasma catecholamines in myocardial infarction

The Abstract reports elevated plasma catecholamines in most patients during the first 48 hours of myocardial infarction. But the paper does not report transient hypokalaemia or suggest that catecholamines cause it; the Methods mention serum potassium only to note that it was normal in one patient. (LLM, conf=0.85)

The Methods passage (page unavailable) says only that serum potassium was normal in one patient; it does not address hypokalaemia or its cause. A search for diuretic therapy, potassium supplementation, and transient hypokalaemia found no passage in our copy that supports the attributed claim. (LLM, conf=0.74)

The Methods passage mentions normal serum potassium in one patient, but does not describe hypokalaemia or its resolution. The paper discusses changes in ventricular arrhythmias, not potassium levels; searches for hypokalaemia, potassium supplements, and diuretic therapy found no passage supporting the attributed claim. (LLM, conf=0.76)

The Methods passage (page not provided) mentions normal serum potassium in one patient, but does not describe hypokalaemia or its duration. The Discussion describes a spontaneous decline in ventricular arrhythmias, not potassium levels. Searches for hypokalaemia, potassium supplements, and diuretic therapy found no passage addressing the claim. (LLM, conf=0.76)

The Methods passage says electrolytes were measured, but the passages concerning urinary excretion discuss catecholamines, not potassium. A search for hypokalaemia, haemodilution, and urinary potassium excretion found no passage in our copy addressing whether those mechanisms explain hypokalaemia after myocardial infarction.
