Why the study?
Tachycardia-induced cardiomyopathy is a common cause of reversible cardiomyopathy, but data remain limited, particularly among young adults.
Does guideline-directed medical therapy improve left ventricular ejection fraction and heart rate in a young adult with tachycardia-induced cardiomyopathy?

Key result
Guideline-directed medical therapy improved left ventricular ejection fraction from 45-50% to 55-60% within four weeks in a 31-year-old woman with tachycardia-induced cardiomyopathy.

Does guideline-directed medical therapy improve left ventricular ejection fraction and heart rate in a young adult with tachycardia-induced cardiomyopathy?
Early identification and treatment of tachycardia-induced cardiomyopathy with rate control and guideline-directed medical therapy can lead to rapid improvement in ventricular function.
Tolu-Akinnawo et al. (2023) conducted a case report in Tachycardia-induced cardiomyopathy (n=1). Guideline-directed medical therapy (beta blockers, ACE inhibitors, spironolactone) was evaluated on Left ventricular ejection fraction. Guideline-directed medical therapy improved left ventricular ejection fraction from 45-50% to 55-60% within four weeks in a 31-year-old woman with tachycardia-induced cardiomyopathy.
