Glyceryl trinitrate for snakebite: Aus research
AUSTRALIAN researchers say they have discovered a potential new first-aid treatment for snakebite. Applying glyceryl trinitrate ointment to a snakebite wound could markedly improve survival, as it slows the transport of venom through the lymphatic system, they said. Coupled with existing first aid, such as pressure bandaging with immobilisation, the angina cream could “buy time” for patients, particularly in remote areas, said the scientists from the Hunter Medical Research Institute and University of Newcastle. “Many snake venom toxins do not enter the bloodstream directly but are absorbed and transported by lymphatic vessels before entering the veins ...
Clinical diagnosis beats ECG in angina
ECGs remain necessary but are no more effective than a thorough clinical assessment at predicting the risk of coronary heart disease in patients with suspected angina, research shows. A UK multicentre trial conducted clinical assessments and resting ECGs on 8176 patients with new-onset chest pain. More than half the patients underwent an exercise ECG. After six years, clinical assessments predicted mortality rates from coronary heart disease and non-fatal acute coronary syndrome to a similar degree as clinical assessment plus resting ECG or clinical assessment plus resting and exercise ECGs. However, 47% of the cardiovascular events occurred ...
GPs urged to redouble effort to meet CVD target
THE MAJORITY of patients with cardiovascular disease are not meeting Heart Foundation goals for a range of management targets, research has shown. A study of 2031 stable angina patients attending GP practices around Australia found only 14% achieved both a BMI of less than 25 kg/m 2 and waist measurement of less than 94 cm for men and 80 cm for women. Around 24% of patients met the BMI target alone, and 23% met waist circumference targets. While more than two-thirds of patients achieved their HDL cholesterol target (greater than 1.0 mmol/L), only 50% met ...
Cardiac stress test criteria questioned
GUIDELINES recommending cardiac stress tests only for coronary heart disease patients with angina may have to be reconsidered, with research revealing many at-risk patients do not experience angina. A US prospective study of 937 outpatients with stable coronary heart disease found nearly a quarter had experienced inducible ischaemia. Of these, more than 80% did not report angina before testing. Those with inducible ischaemia, but without angina, had a greater than twofold increased risk of myocardial infarction or CHD-related death. The findings call into question US guidelines recommending tests only in patients who report symptoms of angina. ...
