ABSTRACT
Introduction: Exercise capacity (VO2 max) is affected by many factors, for example cardiorespiratory fitness, obesity, comorbidities (hypertension and metabolic syndrome), and advanced age. Identification of factors that can affect exercise capacity is extremely important because its reversals can enhance the patients ' life quality and have an impact on their survival as their exercise capacity is related to prognosis in healthy people and in heart disease patients.
Material and methods: The cross-sectional study was done in “Haldiram and Moolchand Heart Centre”, PBM Hospital, S.P. Medical College, Bikaner by estimating exercise capacity (VO2 max) by bruce protocol through treadmill test in different age groups and left ventricle diastolic functions determined by echocardiography were graded into normal, mild to moderate and severe diastolic dysfunction. Exercise capacity (VO2 max) of different age groups was compared with different grades of left ventricle diastolic function.
Results: There was significant difference between the exercise capacity (VO2 max) of participants with normal diastolic function and abnormal diastolic function with respect to different age groups
Discussion: Exercise capacity declines with increase in age but this decline was steeper in abnormal diastolic function as compared to normal diastolic dysfunction. Diastolic function impact VO2 max by their role in producing optimum cardiac output. The preservation of ample left ventricular filling for ensuring proper heart performance during exercise requires the capacity to attain rates of diastolic filling higher than the rates of ejection during the systole.
Conclusion: We have seen that a significant difference between diastolic dysfunction and age that rises steadily with age, with a steeper decline in VO2max of abnormal diastolic function relative to those of normal diastolic function.
Key words: exercise capacity: VO2max, diastolic function, exercise capacity, age
