The age and CVRF (family history of hypertension, diabetes mellitus, smoking, sedentary lifestyle and dyslipidemia) were variables based on the interview conducted on the patient. Sociodemographic Characterization: The data on age, sex, weight, height and cardiovascular risk factors (CVRF) were recorded on the day when the patients underwent echocardiography. Sociodemographic, clinical and echocardiographic variables were collected. Patients with other non-high blood pressure related heart diseases and patients younger than 18 years were excluded. All hypertensive patients who underwent two-dimensional transthoracic echocardiographic and Doppler study in the 2 nd quarter of 2012, in both centers were included. Materials and MethodsĬross-sectional descriptive observational study carried out in two diagnostic centers in Luanda. The objective of the present study is to evaluate the prevalence of left ventricular geometric patterns in hypertensive patients in Angola, as well as to describe sociodemographic, clinical and echocardiographic aspects of the study population. Studies have shown that the incidence of cardiovascular events is higher in patients with CH, intermediate in those with CR and EH geometric patterns, and lower in patients with NG. They are normal geometry (NG) with LVMI and normal RWT concentric remodelling (CR) - normal LVMI and increased RWT eccentric hypertrophy EH - LVMI increase and normal RWT concentric hypertrophy (CH), with increased LVMI and RWT. The various forms of left ventricular (LV) adaptation to uncontrolled hypertension were described in four different geometric patterns using combinations of left ventricular mass index (LVMI) and relative wall thickness (RWT). Left ventricular hypertrophy (LVH) is a known complication of SHA that has long been recognized as an independent risk factor for adverse outcomes in hypertensive patients. In Angola, systemic arterial hypertension (SAH) is the most frequent chronic non-communicable disease, with an estimated prevalence of 23%. Systemic arterial hypertension left ventricular geometry transthoracic echocardiography Introduction The need for longitudinal studies assessing the prognostic value of geometric patterns in hypertensive patients in Angola, as well as their relationship with left ventricular function is imperative. Diastolic dysfunction is present in majority of the patients. Regarding left ventricular function 87% of had normal systolic function, 64% had diastolic dysfunction.Ĭonclusion: The results show that concentric and eccentric hypertrophy is the most frequent geometric patterns. 49% had concentric hypertrophy, 20% had eccentric hypertrophy, and 17% concentric remodelling and 14% had normal geometry. Results: 84 patients were included, 33 males and 51 females, the mean age was 52.7 (± 13.4) years. The relative wall thickness and the presence or absence of echocardiographic left ventricular hypertrophy was used to determine the various geometric patterns. The echocardiographic study was performed according to the ASE recommendations. We included all hypertensive patients who underwent transthoracic echocardiographic study in the 2nd quarter of 2012 in both centers. Methodology: cross-sectional descriptive observational study performed in two diagnostic centers in Luanda.
Considering all patients with LV hypertrophy as a homogenous group is inconsistent with our understanding of the various remodeling patterns that are discussed in this review.Aim: The aim of the present study is to evaluate the prevalence of left ventricular geometric patterns in hypertensive patients in Angola. Some patterns of remodeling are associated with adverse outcomes whereas others appear to be adaptive and physiologic without adverse consequences.
These various architectural changes generally include the development of LV hypertrophy in a pattern that is closely related to the type of injury or overload, and they are accompanied by differences in cardiac function and hemodynamics. Consideration of LV volume, mass, and relative wall thickness (or mass/volume) allows classification of LV remodeling that includes virtually all LV remodeling changes that are seen in health and disease. Such architectural remodeling can be classified as eccentric or concentric. The changes in left ventricular (LV) structure and geometry that evolve after myocardial injury or overload usually involve chamber dilation and/or hypertrophy.
