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 II

• adults between 20 years and 80 or years

  • Chronic respiratory disease

• FEV1/FVC < 0.7 or FEV1< 0.8 of predicted value in pulmonary function test

• bronchiectasis in more than one lobe on chest computed tomography

• FVC or DLCO < 0.8 of predicted value in pulmonary function test

  • Chronic cardiovascular disease

• Reperfusion Therapy for angina pectoris or myocardial infarction

• Heart failure with reduced ejection fraction (LVEF < 50%)

Exclusion Criteria:

• history of acute exacerbation within 4 weeks
• unable to comply rehabilitation program
• not suitable for study on decision by duty physician
