Hypertension, Introduction.
Hypertension is one of the most important preventable causes of premature morbidity and mortality in the UK. Hypertension is a major risk factor for stroke (ischemic and haemorrhagic), myocardial infarction, heart failure, chronic kidney disease, cognitive decline and premature death. Untreated hypertension may result in vascular and renal damage that can culminate in a treatment-resistant state.
