Self-monitoring improves control of high blood pressure compared with GP monitoring alone
Allowing patients who have inadequately controlled high blood pressure to monitor their own blood pressure at home helps their GPs to optimise their management. Patients who self-monitor and visit or talk to their GP when needed for medication adjustments achieve 4mmHg lower systolic blood pressure over 12 months compared with those relying only on the measurements made by a GP without self-monitoring.
Effects are similar if patients write down their measurements to send to the GP or do so via ...
Alternative sedative reduces the risk of acute kidney injury following cardiac surgery
The sedative drug dexmedetomidine can reduce the risk of acute kidney injury when given during non-emergency cardiac surgery. Trial participants who received dexmedetomidine were a third less likely to develop acute kidney injury than those receiving placebo or other treatments. There was no difference in mortality or length of hospital stay.
This systematic review identified 10 studies of 1,575 participants. Surgical procedures included coronary artery bypass grafting with or without valve sur...
Oral ibuprofen may be an option for closing patent ductus arteriosus in premature babies
A high dose of oral ibuprofen was more likely to close a patent ductus arteriosus in premature babies when compared with standard doses of intravenous ibuprofen or indometacin.
Before birth, a baby's lungs aren't needed for breathing. Most blood bypasses the lungs through a large vessel called the ductus arteriosus directly from the pulmonary artery into the aorta to supply the main circulation. Once born, blood flows through the lungs, and the ductus arteriosus usually closes in the fi...
Exercise improves intermittent claudication leg pain on walking
People with intermittent claudication who participate in structured exercise programmes can walk about 80 metres further without experiencing leg pain than those who do not do the programme. They can also walk about 120 metres further overall.
Intermittent claudication is a cramp-like pain in the legs caused by narrowing of the arteries, which restricts blood flow to the muscles. There’s increasing evidence that maintaining physical activity can help. This updated systematic review combin...
Adding a third antiplatelet drug after a stroke doesn’t reduce the risk of another stroke
A combination of aspirin, clopidogrel and dipyridamole does not reduce the incidence or severity of recurrent stroke in people who have had a stroke or transient ischaemic attack (TIA).
This NIHR-funded trial compared the triple treatment to current guideline-based antiplatelet therapy for preventing further stroke or TIA (brief loss of blood supply to the brain). UK guidance recommends aspirin initially followed by clopidogrel alone as for most people this gives the best balance of effectivene...
Imaging is the only way to diagnose blood clots in pregnancy
No blood test can accurately tell if a pregnant or recently pregnant woman has a blood clot. All pregnant women with a suspected clot should continue to have imaging investigations as per current UK guidelines.
This NIHR-funded study recruited 328 pregnant or postpartum women with a suspected blood clot in the lung (pulmonary embolism) or leg (deep vein thrombosis). They had a blood test to measure the levels of 13 biomarkers, such as the D-dimer, to see if they could rule a blood clot in or ou...
Short-duration dual antiplatelet treatment is possible for older people receiving drug-coated stents
Drug-eluting stents are more effective than bare-metal stents for preventing repeat procedures to open narrowed heart arteries in older adults with coronary heart disease. In this trial both types of stents were used alongside short courses of dual antiplatelet medication, outcomes for those receiving drug-eluting stents were improved with no difference in bleeding complications or rates of in-stent clots.
This multi-centre European study tested 1,200 people aged 75 years or older. Duration of ...
Takeaways linked to increased cardiovascular risk factors and obesity in children
Children who eat takeaways once or more each week have more body fat and higher low-density lipoprotein (LDL) “bad” cholesterol levels than those who never or hardly ever eat them. Their diets were also higher in fat and lower in protein and calcium.
This cross-sectional study looked in depth at eating habits and risk markers for coronary heart disease, obesity and diabetes in 2,529 children in England. Though this type of study can only show an association between takeaways and ris...
Uncertain benefits of BNP blood tests to monitor heart failure treatment
In specialist clinics, using B-type natriuretic peptide (BNP) blood levels to guide treatment in people with chronic heart failure shows promise but did not improve survival for all groups. In this review, the benefit was only seen in patients aged less than 75, who survived an extra 1.5 years on average, and possibly those with poor heart function (reduced ejection fraction). However, there was a reduction in hospital admissions for heart failure for everyone.
BNP is a hormone released from th...
