Patients with sleep apnoea and resistant hypertension have increased risk of heart disease

People with resistant hypertension and sleep apnoea have an increased risk of congestive heart failure, new study results suggests. 
Sleep apnoea

People with resistant hypertension are more likely to experience sleep apnoea than those with non-resistant hypertension, increasing the risk of ischaemic heart events and congestive heart failure, new study results suggests.

Between 2006 and 2010, researchers in the United States studied 470,386 adults with hypertension. Sleep apnoea was identified in 33,682 (7.2%) of the study participants, who were followed up until the end of 2010.

Resistant hypertension is where blood pressure remains elevated despite concurrent use of a diuretic and at least two other anti-hypertensive medications. The researchers found that 9.6% of those with resistant hypertension experienced sleep apnoea compared with 6.8% of those with non-resistant hypertension.

They said that patients with resistant hypertension with sleep apnoea had an increased risk of ischaemic heart disease and congestive heart failure compared with those with sleep apnoea and non-resistant hypertension. However, no differences were seen

They said that patients with resistant hypertension with sleep apnoea had an increased risk of ischaemic heart disease and congestive heart failure compared with those with sleep apnoea and non-resistant hypertension. However, no differences were seen between the two groups in terms of risk of stroke and premature death. 

Lead study author Simran K Bhandari, from the division of nephrology and hypertension at Kaiser Permanente Los Angeles Medical Center in California, said: ‘Our study suggests that the risk for cardiovascular outcomes is increased in sleep apnoea patients with resistant hypertension compared with those with non-resistant hypertension.’
