Key result
In hypertensive patients, an ECG strain pattern was associated with significantly higher extracellular volume fraction (30% vs 27%, P<0.05) and impaired circumferential strain.
Why the study?
Is the ECG strain pattern in hypertensive patients associated with myocardial interstitial fibrosis and impaired myocardial strain on CMR?
Population
100 hypertensive patients and 25 normotensive controls.

ECG strain may mark advanced remodeling in hypertension; hypothesis-generating and should not yet change practice.
Cross-Sectional (n=125)
Is the ECG strain pattern in hypertensive patients associated with myocardial interstitial fibrosis and impaired myocardial strain on CMR?
Absolute Event Rate: 30% vs 27%
p-value: p=<0.05
In hypertensive patients, the ECG strain pattern is a marker of advanced left ventricular hypertrophy, increased interstitial fibrosis, and impaired myocardial circumferential strain.
Rodrigues et al. (2016) conducted a cross-sectional in Hypertension (n=125). ECG strain pattern vs. Hypertensive subjects without ECG strain was evaluated on Extracellular volume fraction (ECV) (p=<0.05). In hypertensive patients, an ECG strain pattern was associated with significantly higher extracellular volume fraction (30% vs 27%, P<0.05) and impaired circumferential strain.
