Efficacy of Smartphone Application Based Rehabilitations in Patients With Chronic Respiratory or Cardiovascular Disease

In Republic of Korea, it is not easy to practice standard pulmonary rehabilitation (PR) or cardiac rehabilitation (CR). In this study, the investigators will provide newly developed smartphone application to patients with chronic respiratory or cardiovascular diseases. The investigators want to confirm whether participants, who perform smartphone application based 12-week PR or CR program, present improved exercise capacity, dyspnea symptom, muscle strength, or quality of life.

Inclusion Criteria:Dyspnea symptom >= mMRC 1 or NYHA IIadults between 20 years and 80 or yearsChronic respiratory diseaseFEV1/FVC < 0.7 or FEV1< 0.8 of predicted value in pulmonary function testbronchiectasis in more than one lobe on chest computed tomographyFVC or DLCO < 0.8 of predicted value in pulmonary function testChronic cardiovascular diseaseReperfusion Therapy for angina pectoris or myocardial infarctionHeart failure with reduced ejection fraction (LVEF < 50%)Exclusion Criteria:history of acute exacerbation within 4 weeksunable to comply rehabilitation programnot suitable for study on decision by duty physicianno consent
