Assessment of Functional Capacity and Inflammatory Markers in Women With Heart Failure With Preserved Ejection Fraction
Assessment of Functional Capacity, Inflammatory Markers and Autonomic Function in Women With Heart Failure With Preserved Ejection Fraction and Previous Coronary Artery Disease
Studienübersicht
Status
Detaillierte Beschreibung
It is well established that systolic heart failure impacts exercise capacity and quality of life, diastolic heart failure however, is not well documented as a condition that reduces physical performance.
To confirm that patients have a diastolic disfunction an echocardiography will be performed, this will also yield the left ventricle ejection fraction to confirm the preserved ejection fraction heart failure diagnostics.
Exercise capacity will be assessed using the distance walked on the six-minute walking test, performed on a 30m corridor.
Pulmonary function will be assessed with spirometry and values of forced vital capacity and forced expired volume in one second will be recorded and compared to the age-predicted values.
Respiratory strength will be determined by maximal pressure achieved on a respiratory manometer.
Peripheral muscular strength will be assessed with a handheld dynamometer. Knee extension strength of the dominant leg will be recorded.
An echocardiography will be performed to assess systolic and diastolic function and ejection fraction.
Heart autonomic function will be evaluated using a heart rate monitor and a computer software to identify the sympathovagal balance.
