Washington D.C.: Western-style diets rich in sugar and physical inactivity with obesity are important behavioural risk factors of heart failure, explains cohort studies and case-control studies. The study was published in The Open Inflammation Journal.
Pre-heart failure may be defined as a state of myocardial dysfunction, which is at high risk for developing complete heart failure. It is similar to pre-diabetes or pre-hypertension for developing diabetes mellitus and hypertension, respectively.
Pre-heart failure is characterised with changes in cardiac muscles that are known as remodelling which may help to keep the blood pumping, but the ventricular walls may eventually weaken and are not able to pump adequate blood to the circulatory system resulting into chronic heart failure.
The heart may have high filling pressure with symptoms of dyspnoea and other congestive symptoms. In this process, aldosterone and cortisol predict medium-term left ventricular remodelling in an attempt to prevent cardiac failure.
In the pathophysiology of cardiomyocyte dysfunction as well as in the conversion of physiological remodelling to pathological remodelling and pre-heart failure to complete heart failure, behavioural risk factors have an important role.
In previous studies, Dhalla et al. have observed subcellular remodelling and alterations in sarcoplasmic reticulum to be important which could be identified early by speckle tracking echocardiography.
In view of the rapid increase in the burden of heart failure in the developed and developing countries, and unmet needs in the early diagnosis and treatment, it is important to find out new risk factors and methods for identification of heart failure in the early stage of pre-heart failure.
This analysis, re-examine, the role of nutritional factors as unmet needs in the pathogenesis and management of heart failure.
This meta-analysis included data from three randomized, controlled single-blind trials, published earlier, The intervention and control groups were compared for behavioural risk factors, food intakes, fatty acid intake and on the ratio of polyunsaturated fatty acid(PUFA)/flavonoid intake respectively in the two groups (n = 1446 vs 1320).
The criteria for the diagnosis of pre-heart failure and heart failure were an electrocardiographic and radiological increase in the size of the heart.
Effects of Indo-Mediterranean style foods on parameters of pre-heart failure and heart failure and arrhythmias were significantly lower in the intervention group compared to the control group. At baseline, all the parameters of heart failure showed no significant differences, between the intervention and control group.
