Elevated high-sensitive troponin I levels in patients with hypertrophic cardiomyopathy were associated with a significantly higher frequency of nonsustained ventricular tachycardia (75% vs 24%).

Are elevated hs-TnI levels associated with increased heart rate and higher frequency of NSVT in patients with hypertrophic cardiomyopathy?
In patients with hypertrophic cardiomyopathy, elevated high-sensitivity troponin I levels are associated with higher maximum heart rates and a greater frequency of nonsustained ventricular tachycardia.
Absolute Event Rate: 75% vs 24%
p-value: p=<0.03
Patients and methods Consecutive patients with HCM, treated and monitored at our clinic, were recruited to the study. Most patients received pharmacotherapy (TABLE
Hładij et al. (Fri,) conducted a observational in Hypertrophic cardiomyopathy (n=32). Elevated hs-TnI (Troponin-positive) vs. Normal-low hs-TnI (Troponin-negative) was evaluated on Nonsustained ventricular tachycardia (NSVT) episodes (p=<0.03). Elevated high-sensitive troponin I levels in patients with hypertrophic cardiomyopathy were associated with a significantly higher frequency of nonsustained ventricular tachycardia (75% vs 24%).
