A man named Adam suddenly collapses and dies of a heart failure and stroke caused by hypertension. His wife Eva refuses to accept that her husband died from this "silent killer" disease, which is hypertension. Hypertension is a condition defined by the World Health Organization as having a blood pressure higher than 135/85 mmHg, and it is estimated that 1 in 10 citizens have potential hypertension, with higher rates in cities, and 1 in 5 citizens in the United States have this silent but deadly disease.
