To assess echocardiographic aspect of Congolese hypertensive patients, and to identify predictive factors of left ventricular hypertrophy (LVH).
A transversal study was lead in Brazzaville from January 2011 to December 2013 (36 months). In total, 1125 hypertensive patients under treatment underwent transthoracic echocardiography. The test was carried out either as part of an initial assessment of the hypertension disease or during the development of evocative symptom or complication. Patients' sociodemographic data and echocardiographic parameters were collected and analyzed.
There were 621 males (55.2%) and 504 females (44.8%), mean age 54.7±12 years. The main indication of the test were the hypertension initial evaluation in 792 cases (70.4%), dyspnea in 122 cases (10.8%), investigation of ischemic stroke in 101 cases (9%), cardiac failure and chest pain in respectively 58 and 52 cases. 5.3±4.7 years known duration of hypertension status was associated with overweight/obesity in 829 cases (73.7%), physical inactivity in 669 cases (59.5%), hypertension family history in 540 cases (48%), diabetes mellitus in 122 cases (10.8%), dyslipidemia in 82 cases (7.3%), smoking in 29 cases (2.6%). Echocardiographic test was abnormal in 590 cases (52.4%) and showed hypertrophic cardiomyopathy in 510 cases (45.2%), dilated and hypertrophic cardiomyopathy in 46 cases (4.1%), dilated cardiomyopathy with systolic dysfunction in 31 cases (2.8%), coronary artery disease in 4 cases (0.4%). LVH was concentric in 470 cases (84.6%), eccentric in 70 cases (12.6%), and in 16 cases (3%), it was a concentric left ventricular remodeling. The left ventricular's systolic ejection fraction average was 70.5±9.3%, relaxation disorders in 480 cases (42.6%). Age, male gender, income, known duration of hypertension and treatment were predictive factors of LVH.
Echocardiographic profile of the Congolese hypertensive is quite various, left ventricular hypertrophy is the most predominant abnormality. Efficient management on the hypertension will lead to reduce its morbidity and mortality.
评估刚果高血压患者的超声心动图表现，并确定左心室肥厚（LVH）的预测因素。
2011年1月至2013年12月（36个月）在布拉柴维尔进行了一项横断面研究。共有1125例接受治疗的高血压患者接受了经胸超声心动图检查。该检查作为高血压疾病初始评估的一部分进行，或在出现提示性症状或并发症时进行。收集并分析患者的社会人口统计学数据和超声心动图参数。
男性621例（55.2%），女性504例（44.8%），平均年龄54.7±12岁。检查的主要指征为高血压初始评估792例（70.4%）、呼吸困难122例（10.8%）；缺血性卒中检查101例（9%）、心力衰竭和胸痛分别为58例和52例。高血压病程5.3±4.7年，829例（73.7%）伴有超重/肥胖，669例（59.5%）身体活动不足，540例（48%）有高血压家族史，122例（10.8%）患有糖尿病，82例（7.3%）患有血脂异常，29例（2.6%）吸烟。超声心动图检查异常590例（52.4%），其中肥厚型心肌病510例（45.2%）、扩张型和肥厚型心肌病46例（4.1%）、伴有收缩功能障碍的扩张型心肌病31例（2.8%）、冠状动脉疾病4例（0.4%）。LVH呈向心性肥厚470例（84.6%）、离心性肥厚70例（12.6%），16例（3%）为向心性左心室重构。左心室收缩射血分数平均为70.5±9.3%，480例（42.6%）存在舒张功能障碍。年龄、男性性别、收入、高血压病程及治疗情况是LVH的预测因素。
刚果高血压患者的超声心动图表现多样，左心室肥厚是最主要的异常表现。对高血压进行有效管理将降低其发病率和死亡率。
