Background:
The detection of impaired physical performance in older adults with cardiovascular disease is essential for clinical management and therapeutic decision-making. There is a requirement for an assessment tool that can be used conveniently, rapidly, and securely in clinical practice for screening decreased physical performance.
Objective:
The present study was performed to evaluate the association of office-based physical assessments with decreased physical performance and to compare the prognostic capability of these assessments in older adults with cardiovascular disease.
Methods:
A total of 1,040 patients aged 75 years and older with cardiovascular disease were included in this analysis. One-leg standing time (OLST) and handgrip strength were measured as office-based physical assessment tools, and short physical performance battery (SPPB), 6-min walk distance, and usual gait speed were also measured at hospital discharge as measurements of physical performance. All-cause mortality was assessed by death registry at the hospital. We examined the association of office-based measures with physical performance and all-cause mortality.
Results:
The areas under the curve of OLST for SPPB < 10, 6-min walk distance < 300 m, and usual gait speed < 1.0 m/s were 0.87 (95% CI 0.83-0.91), 0.83 (95% CI 0.80-0.86), and 0.81 (95% CI 0.78-0.85), respectively. The discrimination abilities of OLST for decreased physical performance were significantly higher than those of handgrip strength. After adjusting for the effects of patient characteristics, the hazard ratio for all-cause mortality in the < 3 s group for OLST was 1.68 (95% CI 1.06-2.67, p = 0.03). Handgrip strength, however, was not significantly associated with mortality risk in these participants.
Conclusion:
Short OLST, in particular < 3 s, is associated with decreased physical performance and elevated mortality risk in elderly patients with cardiovascular disease. OLST can be conveniently measured in the clinician's office as a screening tool for impaired physical performance.

Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.

Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
