Weight control is an important issue not just in your risk of heart attack or high blood pressure. Being overweight or obese can hurt the heart, even in people who don't have heart disease, this can be dangerous for the patients with high blood pressure and patients suffering from diabetes.

Study focused on 150 healthy men and women who averaged 45 years old. None of the participants had heart disease, high blood pressure, type 2 diabetes or any known symptoms of heart failure. Based on body mass index, an indirect measure of body fat, participants were divided into four groups: severely obese (BMI of more than 35), mildly obese (BMI of 30-34.9), overweight (BMI of 25-29.9), and normal (BMI less than 25). Many problems of the heart were revealed by a new kind of ultrasound technology, which the researchers used to get an in-depth look at participants heart muscle and function, as well as treadmill exercise tests and blood samples.

Very advanced techniques showed quite expected results. The pumping option was seen reduced in lower chambers of heart with an obese. This pumping action was seen reduced compared to persons with normal BMI. Therefore people with excess weight had compromised their heart function, even though they were not known to have heart disease.

Although the participants seemed healthy by ordinary screening measures, such as blood pressure reading, electrocardiogram, and ultrasound of the heart, the researchers detected subtle effects of excess weight on the hearts of overweight and obese participants. People not very fat but BMI high than normal, the condition in such person, could be a warning sign of future heart failure, in which the heart can't pump out enough blood.
