Lung restrictive disorder is one of the reasons that induce chronic fatigue in COVID-19 (Corona Virus Disease-19) survivors. It also gives a significant effect on cardiovascular patients who are in the second phase of cardiac rehabilitation. Breathing exercise and chest mobilization are proven to increase lung functional capacity in Covid-19 survivors. On the other hand, there is still no research that shows the effectiveness of Breathing exercises and chest mobilization in Covid-19 survivors who are suffering from cardiovascular problems.~Patients in National Cardiac Center Hospital, Jakarta, with a history of Covid-19 and have cardiovascular disease are recruited. They will undergo pre and post-exercise examinations such as blood sampling, do 6 minutes walking test, Peak Cough Flow and Peak Flow Rate test, measuring the chest dimension, treadmill, and answer the European Quality of Life Five Dimension (EQ-5D) questions. With randomization, patients will be determined to treatment or control group. They will be prepared about what exercises should they do at home. Subjects will be supervised digitally and regularly through Zoom meetings. Exercises will be done for 3 months.
Objective propose: to investigate the effect of home based breathing exercise and chest mobilization on the cardiorespiratory functional capacity of Covid-19 survivors with cardiovascular comorbidity.~Breathing exercise and chest mobilization are proven to increase lung functional capacity in Covid-19 survivors. It is hypothesized that breathing exercise and chest mobilization in Covid-19 survivors will give benefits to Covid-19 survivors with cardiovascular disease.
