The relationship between knowledge and self-care behavior of acute coronary syndrome patients at the Heart Polyclinic of PKU Muhammadiyah Gamping Hospital
Keywords:
acute coronary syndrome, education, knowledge, self-careAbstract
Acute Coronary syndrome (ACS) is an acute manifestation of Coronary Heart Disease (CHD), which remains a
leading cause of morbidity and mortality worldwide, including in Indonesia. The implementation of self-care
behavior is essential for ACS patients to prevent recurrence and improve quality of life. Knowledge is a key factor
influencing self-care behavior among ACS patients at the Cardiology Clinic of PKU Muhammadiyah Gamping
Hospital in Yogyakarta. This research method used a quantitative correlation design with a cross-sectional
approach. A total of 86 respondents were selected using purposive sampling. The instruments used were the HDFQ
and SC-CHDI questionnaires. The results showed that some respondents had good knowledge (39.5%), but the
majority demonstrated suboptimal self-care behavior (62.8%). The results of the Spearman rank test revealed a
significant positive correlation between knowledge and self-care behavior (p=0.001, r=0.425). This study suggests
that continuous education is necessary to improve patient knowledge, thus enhancing optimal self-care behavior.
