Call for cardiologists to be active post-op and other findings at major Euro-conference

Tuesday August 28th, 2018

Three complications are responsible for 75% of post-operative deaths following non-cardiac surgery, according to a major international study.

Myocardial injury – responsible for 29% of deaths – is the leading cause following by haemorrhage – 25% of deaths – and sepsis, responsible for 20% of deaths, according to the findings, reported to the conference of the European Society of Cardiology, meeting in Munich, Germany, yesterday.

Canadian researchers examined outcomes for 40,000 patients over the age of 45 from 27 centres in 14 countries in every inhabited continent.

Some 715 patients died within 30 days of surgery.

The researchers say the findings suggest that cardiologists should play an increased role in post-operative care.

Researcher Professor Philip J. Devereaux, of McMaster University, Hamilton, Canada, said: “We’re letting patients down in postoperative management.

“The study suggests that most deaths after noncardiac surgery are due to cardiovascular causes, so cardiologists have a major role to play to improve patient safety.

“This includes conducting blood and imaging tests to identify patients at risk then giving preventive treatment, including medications that prevent abnormal heart rhythms, lower blood pressure and cholesterol, and prevent blood clots.”

Fish oil supplements do not prevent heart attack or strokes in patients with diabetes, British researchers reported to the conference.

The findings come from a randomised trial of the treatment involving 15,000 patients over six years, conducted by Dr Louise Bowman, of Oxford University.

The appetite suppressant, Lorcaserin, does not increase cardiovascular risk – but nor does it reduce it, according to a US based trial.

A randomised study involved 12,000 adults in 473 centres in eight countries. About 12% of those taking the drug – and those on placebo – needed hospitalisation for cardiovascular events during the study.

This was even though patients taking the drug achieved greater weight loss than those taking placebo.

Giving oxygen therapy to patients with acute myocardial infarction does not prevent heart failure, according to Swedish researchers.

Researchers at the Karolinska Institutet arranged for randomised treatment to be given to more than 6,000 patients at 35 Swedish hospitals.

Deep forehead wrinkles may be an indicator of increased cardiovascular risk, according to a French study. Researchers found that people with multiple wrinkles had ten times the risk of dying than those with none – even allowing for smoking status and other factors.

Researchers at the Centre Hospitalier Universitaire de Toulouse studied more than 3,200 adults over a period of 20 years.

People who routinely sleep five hours or less a night face a doubled risk of suffering major cardiovascular events compared with those taking seven or eight hours, Swedish researchers reported.

Researchers at the University of Gothenburg, Sweden, studied some 798 people over a period of 21 years.

A metanalysis conducted by researchers at the Onassis Cardiac Surgery Centre, Athens, Greece, reached similar conclusions.

New guidelines were issued on the definition of myocardial infarction.

The international guidelines, agreed by the European Society of Cardiology, the World Heart Federation and two US organisations, set out new details on the diagnosis of type 2 MI, which is caused by conditions such as respiratory failure or severe hypertension.
