Insights
Hypertension can impair heart function. This study shows that while radial systolic function may initially increase, hypertrophic remodeling leads to reduced radial function and hidden longitudinal systolic dysfunction in hypertensive patients.
Area of Science:
- Cardiology
- Cardiovascular Imaging
- Hypertension Research
Background:
- Systolic reserve is a key compensatory mechanism for the heart facing increased afterload.
- Longitudinal systolic dysfunction is known in hypertensive hearts, but radial and circumferential function require further investigation.
- Left ventricular geometry plays a crucial role in cardiac function and adaptation to hypertension.
Purpose of the Study:
- To investigate three-directional systolic function in asymptomatic hypertensive patients.
- To examine the relationship between systolic function and left ventricular geometry.
- To utilize two-dimensional speckle-tracking imaging for detailed functional analysis.
Main Methods:
- Echocardiographic evaluations were conducted on 74 hypertensive patients and 55 age-matched controls.
- Two-dimensional speckle-tracking imaging was employed to assess systolic function.
- Left ventricular geometry was analyzed in relation to systolic performance.
Main Results:
- Longitudinal strain was significantly reduced in hypertensive patients with concentric and eccentric hypertrophy compared to controls.
- Radial strain was elevated in hypertensive patients with normal geometry but attenuated in those with other geometric patterns.
- These findings suggest a complex interplay between cardiac remodeling and systolic function in hypertension.
Conclusions:
- Hypertrophic remodeling negatively impacts the compensatory increase in radial systolic function.
- Latent longitudinal systolic dysfunction is associated with altered left ventricular geometry in hypertensive individuals.
- These results highlight the importance of assessing multi-directional systolic function in hypertensive heart disease.
Background:
Systolic reserve is an important compensatory mechanism against increasing afterload. Although longitudinal systolic dysfunction with preserved ejection fraction has been reported in hypertensive hearts, radial and circumferential function has not been fully examined. The aim of this study was to investigate three-directional systolic function and its relationships with left ventricular geometry in asymptomatic hypertensive patients using two-dimensional speckle-tracking imaging.
Methods:
Echocardiographic evaluations were performed in 74 hypertensive patients and 55 age-matched control subjects.
Results:
Longitudinal strain was significantly reduced in the hypertrophy groups compared with that in control subjects (concentric, -15.1 ± 4.0%; eccentric, -15.9 ± 4.4%; control, -18.9 ± 3.3%; P < .05). Conversely, radial strain was significantly higher in the normal geometry group than in control subjects (53.8 ± 19.4% vs 40.3 ± 15.1%, P < .05). However, this augmentation was attenuated in the other geometries.
Conclusion:
Hypertrophic remodeling attenuates compensatory augmentation of radial systolic function and is associated with latent longitudinal systolic dysfunction.
