May Measurement Month 2019: an analysis of blood pressure screening results from Angola.

Raised blood pressure (BP) is the biggest risk factor that contributes to the global burden of disease and mortality. May Measurement Month (MMM) is a global initiative aimed to improved awareness of BP and has been a temporary solution to the lack of screening programmes. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2019. Blood pressure measurement, the definition of hypertension, and statistical analysis followed the standard MMM protocol. In total, 7112 individuals were screened (mean age 41.3 years; 50.4% female; 99.5% black) in 6 of the 18 Angolan provinces. In total, 99.6% of screenees provided three BP readings with an average BP of the 2nd and 3rd readings of 126/81 mmHg. After imputation, 2745 (38.6%) had hypertension of whom 1389 (59.8%) were aware of their diagnosis and 50.6% were on antihypertensive medication. Of those 1389 treated participants, 41.2% were controlled (<140/90 mmHg) and of all hypertensive individuals, 20.8% were controlled. Also, 1356 individuals had untreated hypertension and 817 were inadequately treated. Angolan MMM19 follows on from the MMM17 (n = 17481) and MMM18 (n = 14433) studies, which were the largest BP screening campaigns undertaken in Angola. The 2019 results showed a high percentage of hypertensive individuals and almost 2200 adults had either untreated or inadequately treated hypertension, demonstrating that there is work to do but also that the Angolan MMM is being effective at raising awareness at least among these individuals.

Values of left ventricular diastolic function assessed by left atrial volumes and Doppler echocardiography in healthy Angolans: Effect of age and gender: A pilot study.

INTRODUCTION: Studies about the reference values of conventional and tissue Doppler echocardiography in African populations are limited. OBJECTIVES: To evaluate the effect of aging and gender in left ventricular diastolic function assessed by conventional and tissue Doppler echocardiography in healthy Angolans. METHODS: Cross-sectional study involving healthy adult participants attending a diagnostic center in Luanda, Angola. Two-dimensional transthoracic B-mode and Doppler echocardiography were performed according to the Guidelines of the American Society of Echocardiography and the European Association of Cardiovascular Imaging. RESULTS: A total of 103 men (47.5%) (mean age: 39.5 ± 10.8) and 114 women (52.5%) (mean age: 43.0 ± 12.5 years) were included. Women were older (p = 0.025) and showed smaller body surface area (p < 0.001) than men. Mitral E velocity and E/e' ratio were higher in women than in men. While DT of mitral E velocity was longer in men than in women (p = 0.041), E velocity, E/A ratio, and average e' velocity showed a negative significant correlation with increasing age (r - 0.33; p ≤ 0.001; r - 0.48; p ≤ 0.001 and r - 0.41; p ≤ 0.0001, respectively). Conversely, A wave velocity showed a significant positive correlation with age (r 0.47; p < 0.001). CONCLUSIONS: In a healthy Angolan adult population, the variables of left ventricular diastolic function declined with age, reflecting a normal aging process. This must be taken into account when assessing diastolic function at different age categories.

May Measurement Month 2018: an analysis of blood pressure screening results from Angola.

Elevated blood pressure (BP) is a growing burden worldwide with high prevalence in the world and with a huge impact on public health. May Measurement Month (MMM) is a global initiative aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programmes. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2018. Blood pressure measurement, the definition of hypertension and statistical analysis followed the standard MMM protocol. In Angola 14 433 individuals (mean age 38.6 years; 53.7% female; 99.9% black) in 6 of 18 provinces were screened. In total, 99.0% of screenees provided three BP readings with an average BP from 2nd and 3rd reading of 126/80 mmHg. After imputation, 4844 (33.6%) had hypertension of whom 54.2% were aware of their diagnosis and 46.3% were on antihypertensive medication. Of those medicated, 42.6% were controlled and of all hypertensive individuals, 19.7% were controlled. We screened 2603 individuals with untreated hypertension and 1285 with inadequately treated hypertension. Angolan MMM18 emerges as a continuation of the Angolan MMM17 study, the largest BP screening campaign undertaken in Angola, enabling us to compare the 2 years. This year's results also showed a high percentage of hypertensive individuals and almost 3900 adults with untreated or inadequately treated hypertension, demonstrating that there is still a long way to go but also that the Angolan MMM is being effective at raising awareness at least among these individuals.

May Measurement Month 2017: an analysis of blood pressure screening in Angola-Sub-Saharan Africa.

Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. May Measurement Month (MMM) is a global initiative aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programmes worldwide. There is increasing prevalence of hypertension in developing countries leading to increased risk of adverse outcomes. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2017. Blood pressure measurement, the definition of hypertension and statistical analysis followed the standard MMM protocol. In Angola, 17 481 individuals were screened in six provinces with an average BP of 126/78 mmHg. After multiple imputation, 6022 (34.5%) had hypertension. Of individuals not receiving antihypertensive medication, 4080 (26.3%) were hypertensive. Of those receiving antihypertensive medication, 1159 (59.7%) had uncontrolled BP. MMM17 was the largest BP screening campaign undertaken in Angola. These results suggest that there is still a significant percentage of patients who are not medicated and possibly require medication, and more than half of the hypertensive patients do not have controlled BP demonstrating the need for a more targeted and comprehensive screening of BP and more effective treatment.
