Key result
Metoprolol reduced left ventricular filling pressure at rest (16 to 12 mmHg) and increased stroke volume at rest (53 to 70 ml) and exercise significantly more than captopril over 3 months.
Why the study?
Does metoprolol improve haemodynamic parameters compared to captopril in patients with idiopathic dilated cardiomyopathy?
Does metoprolol improve haemodynamic parameters compared to captopril in patients with idiopathic dilated cardiomyopathy?
Metoprolol provides more favorable hemodynamic improvements, specifically in resting left ventricular filling pressure and stroke volume, compared to captopril in patients with idiopathic dilated cardiomyopathy.
No takes yet. Share an insight, caveat, or question.
May favor metoprolol over captopril for hemodynamics in idiopathic dilated cardiomyopathy; hypothesis-generating and requires randomized confirmation.
Jansson et al. (1997) studied idiopathic dilated cardiomyopathy (n=54). Metoprolol vs. Captopril was evaluated on Haemodynamic effects (left ventricular filling pressure and stroke volume). Metoprolol reduced left ventricular filling pressure at rest (16 to 12 mmHg) and increased stroke volume at rest (53 to 70 ml) and exercise significantly more than captopril over 3 months.
