Hypertension has been described as a global epidemic. Despite the expanded use of antihypertensive medication, the number of people diagnosed with the condition keeps increasing. In some countries, as many as 50% of the population older than 60 years is hypertensive. In South Africa, the prevalence is 35.1%. In 2017, the American College of Cardiology/American Heart Association’s guideline redefined the threshold for hypertension as blood pressure (BP) of 130/80mmHg on at least two occasions.
