[The role of tissue myocardial dopplerechocardiography in early detection of structural-functional changes in the myocardium of patients with mild and moderate arterial hypertension].
AIM: To study structural and functional changes in left ventricular myocardium (LVM) of patients with mild and moderate arterial hypertension (AH) with application of tissue myocardial dopplerechocardiography (TMD), correlation between these changes and parameters of electrophysiological remodeling and circadian profile of blood pressure.
MATERIAL AND METHODS: Forty-give hypertensive patients were divided into two groups: the study group 2A consisted of 28 patients with mild AH (144.2 +/- 5.8/89.4 +/- 6.6 mm Hg), group 2B - of 17 patients with moderate AH (160.5 +/- 9.1/101.3 +/- 10.2 mm Hg). The control group consisted of 10 normotensive subjects. All the patients were examined using standard echocardiography with assessment of transmitral blood flow, tissue doppler investigation, circadian monitoring of blood pressure, electro-, vector- and decartocardiography.
RESULTS: No significant differences in standard doppler, electro- and vectorcardiographic parameters between the patients with mild and moderate hypertension were found. LVM mass index and LV wall relative thickness significantly increased both in 2A and 2B groups vs controls (p < 0.05). Most patients of group 2A and 50% patients of group 2B had no alterations in LV geometry. Lower blood pressure was associated with LV concentric remodeling, higher - with concentric and excentric hypertrophy. In the presence of LV remodeling hypertensive patients developed more pronounced disorders of diastolic function according to TMD compared to hypertensive patients with normal LV geometry (p < 0.05). TMD detected LV diastolic disorders in 82% patients of group 2A and in 94% - of group 2B, while transmitral doppler study detected diastolic dysfunction only in 14 and 29% patients, respectively. A significant difference by Em/Am was registered between patients with mild and moderate AH only in the area of the mitral ring at the side of LV posterior wall (p < 0.05).
CONCLUSION: TMD is able to detect earleast structural-functional myocardial changes in hypertensive patients and to determine significant differences in LV diastolic disorders in patients with mild and moderate AH. No significant differences in LVM mass, standard doppler, electro- and vector-cardiographic parameters were found between AH patients' groups.
