New Research From Scientists Reveal Strong Connection Between Obesity And Heart Failure

By Charlie Carmichael

New research from  scientists has revealed that obesity could be a driver of hearts starting to fail, according to researchers.

According to the findings, those with higher BMI’s and waist-to-hip ratios, showed around a 30% increased risk of heart failure.  The findings presented at the British Cardiovascular Society conference in Manchester provides great incentive for those suffering from obesity to address their excess weight as quickly and efficiently as possible.

In the largest study of its kind, scientists at Queen Mary University of London  collaborated with experts from  University of Oxford and Southampton University on the research, examining the scans of more than 30-thousand overweight people.

They found the heart muscle was thicker,  and there were more signs of scarring and the main pumping chamber was weaker, making it more difficult for the heart to effectively pump blood around the body and could lead to the development of heart failure.

The experts concluded that obesity changes the structure of the heart, making its failure almost a third more likely. The risk occurred regardless of other risks for heart failure such as diabetes, high blood pressure and high cholesterol.

Scientists at Queen Mary University of London worked in collaboration with the University of Oxford and Southampton University on the research.

CMR scans are a type of heart scan used to diagnose and give information on various heart conditions, and the people were chosen at random to have a scan.

The study found that when the heart scans of people with a higher BMI and waist-to-hip ratio were compared with those for people within the healthy range, the hearts of obese people had undergone structural changes.

Dr Zahra Raisi-Estabragh, from Queen Mary University of London, who supervised the study, said: “We already know that obesity increases the risk of heart and circulatory diseases that can go on to cause heart failure.

“But now we have revealed that obesity itself could be a driver of hearts starting to fail.

“Further research could provide new insights into the biological mechanisms through which obesity leads to poorer heart health.”

The research was funded by the British Heart Foundation (BHF).
