Heart failure & cardiomyopathiesCross-sectional study
Increased Myocardial Stiffness in Patients With High-Risk Left Ventricular Hypertrophy
- Cross-sectional study
- age- and sex-matched controls
- right heart catheterization
- 3-dimensional echocardiography
- preload manipulation
Authors' conclusion
LV myocardial stiffness in patients with LVH and elevated biomarkers (stage-B HFpEF) is greater than in age- and sex-matched controls and thus appears to represent a transitional state from a normal healthy heart to HFpEF.
Study context
- Population
- Middle-aged patients with left ventricular hypertrophy (LVH) and elevated cardiac biomarkers (high risk for heart failure with preserved ejection fraction (HFpEF))
- Participants
- 46 vs 61
- Exposure
- LVH with elevated cardiac biomarkers vs healthy controls
- LVHn = 46
- Controln = 61reference
- Outcome
- LV myocardial stiffness (stiffness constant, preload as transmural filling pressure)
