A high-protein diet can help heart failure patients live longer
The functionality of the body in converting the protein into muscle mass decrease as the person ages and there is an inverse association between them. Studies show heart failure risk increases with age and ten percent of the adults aged more than 70 years are at the risk of heart failure. Muscle mass can be maintained by increasing protein consumption. Older adults should consume more protein for good health but they consume less. The United States Department of Agriculture (also known as the Agriculture Department) says elder people require 150 to 200 grams of protein per day.
A European study shows a longer life expectancy in an individual with the enhanced protein consumption among heart failure patients. Foods such as milk and milk products, lentils, beans, soybeans, nuts, seafood, poultry (or chicken), meat and eggs contain protein (also known as macronutrient).
Researchers have conducted 21 months of follow-up studies to find out the survival chances with protein consumption among 2,281 European patients belonging to 11 countries with an average age of 68 years. About 27 percent of them were female. They used BIOSTAT-CHF (BIOlogy Study to TAilored Treatment in Chronic Heart Failure) study data for the investigation purpose. Researchers used urine urea excretion to estimate daily protein consumption and assessed mortality in the participants.
Researchers found that the median protein consumption among the participants is 53 grams per day. The study shows a 31 percent death rate among older people consuming 40 grams or less protein consumption when compared to the 18 percent death rate among people consuming 70 grams or more proteins.
When researchers adjusted the results with factors such as renal function (or kidney function) and age which may influence the final results, the study shows 46 percent higher risk of death among people consuming lowest quartile of protein compared with people consuming the highest quartile of protein. The study results clearly show a better survival chance with the higher consumption of protein among older people and this association is independent of other factors.
Authors say the current study was not intended to find a cause-effect relationship between protein consumption and survival from heart failure. But how much protein consumption is required to prevent heart failure event in older adults is not clear. There is a need to perform a randomized controlled trial to find out the recommended amount of daily protein consumption for elderly people to prevent heart failure events.
Recently, a Chinese nine-year follow-up study has found an 18 percent lower risk of mortality from diseases such as stroke and heart failure with the daily consumption of eggs. Researchers think improvements in the heart health of a patient is due to the increased muscle mass with the consumption of higher protein diet.
The study findings were presented at the World Congress on Heart Failure 2018, an event organized by the European Society of Cardiology, May 26 to 29 in Vienna, Austria. Author of the study was Koen Streng, a Ph.D. student, the University Medical Center Groningen (UMCG), the Netherlands.
