[Functional recovery in older inpatients with hypertension and ischemic heart disease post-COVID-19.]

Understanding the recovery process of functional abilities post-COVID-19 in older inpatients with arterial hypertension and ischemic heart disease is important for optimising healthcare delivery and resources. Participants in this study were individuals undergoing hospital-based rehabilitation following COVID-19 (average age 66, n=183). They were categorised into groups with arterial hypertension (n=92), ischemic heart disease (n=18), both conditions (n=38), and a control group without these diseases (n=35). Functional abilities were assessed via the distance walked until signs of exhaustion (meters), handgrip strength (kilograms), and breath-holding time (seconds). Multiple regression analysis revealed that inpatients with arterial hypertension walked shorter distances (ß=-19,183; p=0,050) but showed higher handgrip strength (ß=3,735; p=0,025) compared to the control group. Post-rehabilitation, inpatients with hypertension demonstrated greater performance (ß=40,435, p=0,024) and better improvement rates (ß=47,337; p=0,016) in walked distance than those in the control group. Significant interaction effects between groups and pre-/post-rehabilitation changes were observed only for walking distance (ß=34,74; p=0,02), with no significant interactions found for other measures. The findings indicate that older inpatients with arterial hypertension may experience comparable or enhanced recovery of functional abilities post-COVID-19. The presence of ischemic heart disease, alone or combined with hypertension, does not significantly impair rehabilitation outcomes compared to those without such conditions.

[Changes in respiratory function and physical performance in middle-aged and old inpatients recovering from COVID-19 after a rehabilitation program.]

Changes in respiratory and physical performance in geriatric inpatients recovering from COVID-19 are of interest for rehabilitation interventions. 56 inpatients (67% women), average age 64±11 years recovering from COVID-19 underwent a comprehensive rehabilitation program (16,9±3,8 days). After the rehabilitation program, the patients showed an improvement in respiratory function: voluntary breath-holding after inhalation - by 19% (p=0,006), breath-holding after exhalation - by 25% (p=0,026), lungs computed tomography (p<0,001); physical performance: handgrip strength - by 14% (p=0,083), preferred walking speed - by 80% (p=0,025); exercise tolerance: distance walked until the first signs of fatigue - by 227% (p<0,001), resting heart rate - by 1% (p=0,011). The interaction of rehabilitation time and patient sex was statically nonsignificant across all variables of interest. The rates of changes in respiratory function and physical performance were significant and exceeded similar changes recorded in healthy old people who begin an exercise program. However, in absolute values, respiratory function and physical performance values after the rehabilitation were lower than reference values for this age group. These results can be valuable for clinicians when designing a rehabilitation program for geriatric patients recovering from COVID-19.
