Consenso de expertos sobre el manejo clínico de la hipertensión arterial en Colombia. Sociedad Colombiana de Cardiología y Cirugía

Abstract

In 2017, the American College of Cardiology (ACC) and the American Heart Association (AHA) concurrently established new guidelines for the prevention, detection, assessment and management of arterial hypertension in adults, based on new scientific evidence supporting its intensive treatment.The formal recommendation was to use lower arterial pressure thresholds for initiating antihypertensive treatment. This consideration arose from studies which related the achievement of lower arterial pressure figures with a significant decrease in the risk of cardiovascular disease and mortality in the hypertensive population.In light of this new definition of arterial hypertension, Muntner et al. consider that the prevalence of hypertension in the United States would be 45.6%, compared with 31.9% if the previously accepted and implemented parameters from the JNC7 were applied. According to this committee, the percentage of American adults recommended for antihypertensive treatment would go from 34.3% to 36.2%, while the percentage of hypertensives not achieving the established goals would increase from 39 to 53.4%.Meanwhile, Bundy et al. reached similar conclusions, calculating that 45.4% of adult Americans over the age of 20 (105.3 million) would have hypertension according to the new classification, compared to data from 2014, which considered 32.0% (74.1 million) to be hypertensive. This 13.5% difference amounts to 31.3 million people who would be classified as hypertensive.In Colombia, the application of the new classification would mean going from a prevalence of 22.0% in 2016 to an estimated 43.3%, currently, just by changing the cut-off value for being considered hypertensive, which would amount to classifying approximately 21 million people as sick.
