Functional Capacity Relationship in Coronary Heart Disease in Complete and Incomplete Post-Revascularization Inpatients

Cardiovascular diseases remain the leading cause of mortality worldwide, with coronary artery disease being the most significant contributor. The management of coronary artery disease, including stable ischemic heart disease and acute coronary syndrome, through non-surgical revascularization procedures has been widely practiced and extensively discussed in the literature, particularly regarding the benefits of complete revascularization. Complete revascularization has been associated with better prognostic outcomes and improved functional capacity in patients compared to incomplete revascularization. This study aims to compare the functional capacity, as measured by the six-minute walk test (6MWT), between patients undergoing complete and incomplete revascularization. The study employed a cross-sectional design and was conducted at Prof. Dr. R.D. Kandou General Hospital, Manado, within the Division of Cardiac Prevention and Rehabilitation. The study population consisted of hospitalized coronary artery disease patients who had undergone revascularization procedures and completed the 6MWT. Data collection took place from October 2020 to October 2023, yielding a total sample of 303 patients. The findings of this study demonstrate a significant difference in the functional capacity, as assessed by the 6MWT, between patients who underwent complete and incomplete revascularization procedures. Patients who underwent complete revascularization exhibited better functional capacity, as indicated by the greater distance covered during the 6MWT, compared to those who underwent incomplete revascularization.
