Influence Of Bmi On Cardiac Output And Peripheral Blood Flow

INFLUENCE OF BMI ON CARDIAC OUTPUT AND PERIPHERAL BLOOD FLOW IN YOUNG ADULT MALES INTRODUCTION: According to WHO, obesity is increasing alarmingly worldwide including India. Obesity is rising as an epidemic globally and according to WHO, one in six people on Earth (approximately one billion) are overweight and, alarmingly, more than 300 million of them are obese. This might be due to more sedentary life style excessive intake of energy rich diet is associated with various chronic diseases thus posing a major public problem. [1][2] High and middle income countries are facing rapid rise in overweight and obesity among children and adolescents as a consequence of easily available, cheap, high caloric foods combined with sedentary lifestyles. [3] The increasing spread of overweight and obesity as epidemic in India is directly related to the increased prevalence of obesity-related co-morbidities; hypertension, metabolic syndrome, dyslipidemia, type 2 diabetes mellitus, and cardiovascular disease.[4][5] The hemodynamic consequences of obesity are increased stroke volume and heart rate and hence cardiac output is increased in obese people. The compensatory adaptation of the hyperdynamic circulation is increased adipose tissue mass at the expense of eccentric left ventricular remodeling. This results in increase in BP in obese. BP measured in young and middle-aged adults is positively related to risk of coronary artery disease in older age implies that the risk ofShow MoreRelatedThe Effect Of Exercise On Heart Rate, Stroke Volume, Total Peripheral Resistance, And Oxygen Consumption2497 Words   |  10 Pagesexercise and cardiorespiratory health and to better understand this correlation, this study analyzes the effect that exerc ise has on heart rate, stroke volume, total peripheral resistance, and oxygen consumption. I hypothesize that those who regularly exercise will overall have lower heart rates, increased stroke volume, lower total peripheral resistance, and higher oxygen consumption. To test my hypothesis, two groups were obtained: active, those who exercised more than seven hours a week, and inactiveRead MoreHeart Failure ( Hf )1821 Words   |  8 Pagesfailure (HF) is a syndrome involving insufficient pumping and/or filling of the heart (Lewis, Heitkemper, Dirkson, Bucher, 2014). As HF progresses, the heart cannot continue to meet the oxygen demands of the body’s tissues due to a decreased cardiac output. Acute HF and chronic HF have replaced the term congestive heart failure (CHF) since not all HF patients experience pulmonary congestion, but CHF is still commonly used in the clinical setting (Lewis et al., 2014). Regardless of the terminologyRead MoreThe Definite Haemodynamic Diagnosi s Of Pulmonary Hypertension7200 Words   |  29 PagesThe definite haemodynamic diagnosis of pulmonary hypertension (PH) requires right heart catheterisation and direct measurements of right ventricular, pulmonary artery and pulmonary capillary wedge pressures and cardiac output. As this is an invasive test with risk and cost implications diagnostic algorithms have been devised that combines clinical assessment, non-imaging cardio-respiratory assessment and non-invasive imaging in patients suspected of having pulmonary hypertension. The initial aimRead MoreThe Importance Of Pulmonary Rehabilitation Within Ild Patients1923 Words   |  8 Pagesbody such as oxygen depletion and increase carbon dioxide concentrations, which alter the pH balance. This homeostatic change stimulates various responses within these two systems to neutralize its effects. Exercise training however, can positively influence the capacity of cardiovascular and respiratory systems to tolerate increasing levels of intensity with less physiological effort thus improving their efficiency. Inflammatory conditions such as Chronic Obstructive Pulmonary Disorder (COPD) and InterstitialRead MoreModule Quizzes Essay14245 Words   |  57 Pagesof life -the relationship broke up.

This prevents people from exercising their bodies regularly. Regular exercise strengthens the bones and muscles and improves circulation of blood inside the body (Makinen et al., 2009). Being active also causes the body to burn more calories allowing a person to maintain a healthy weight. According to studies conducted on the effects of exercise, it has been shown that exercise helps to preventRead MoreComprehensive 1 Essay18452 Words   |  74 Pages  Look for early signs of a lesion that increases in size with a red border, clear center.  Correct C.   See a healthcare provider if nausea, vomiting, and joint pain occur after a tick bite.
