ABSTRACT
OBJECTIVES: High blood pressure (BP) is associated with diastolic dysfunction, but the consequence of elevated BP over the adult life course on diastolic function is unknown. We hypothesised that high BP in earlier adulthood would be associated with impaired diastolic function independent of current BP. METHODS: Participants in the Medical Research Council National Survey of Health and Development birth cohort (n=1653) underwent investigations including echocardiography at age 60-64â years. The relationships between adult BP, antihypertensive treatment (HTT) and echocardiographic measures of diastolic function were assessed using adjusted regression models. RESULTS: Increased systolic BP (SBP) at ages 36, 43 and 53â years was predictive of increased E/e' and increased left atrial volume. These effects were only partially explained by SBP at 60-64â years and increased left ventricular mass. HTT was also associated with poorer diastolic function after adjustment for SBP at 60-64â years. Faster rates of increase in SBP in midlife were also associated with increased poorer diastolic function. CONCLUSIONS: High SBP in midlife is associated with poorer diastolic function at age 60-64â years. Early identification of individuals with high BP or rapid rises in BP may be important for prevention of impaired cardiac function in later life.

A 39-year-old male ex-smoker gave a history of exertional chest pain ever since he suffered a respiratory tract infection. Clinical examination, electrocardiogram and echocardiography were normal and he was referred for a cardiac CT scan to assess coronary artery calcification and patency. The scan demonstrated incidental fistulae between the right internal mammary artery and the right coronary artery, and the left internal mammary artery and the left anterior descending artery.
ABSTRACT
Up to 40% of acute ischaemic strokes in young adults are cryptogenic in nature, that is, no cause is determined. In more than half of these patients, patent foramen ovale (PFO) is seen along with an increased incidence of atrial septal aneurysm. The commonest method of investigation is echocardiography (preferably transoesophageal echocardiography). On the basis of available evidence, low risk patients are treated with antiplatelet agents and high risk patients with warfarin. There are inconclusive data on the efficacy of PFO closure to prevent stroke recurrence. However, if there is recurrent stroke or intolerance to medical therapy, percutaneous closure is carried out.
