Adherence to the medication regimen in patients with heart disease is very important and adherence to treatment is considered as an important factor in better control of disease. The aim of this study was to determine the rate of medication adherence and its related factors in patients with cardiovascular diseases after discharge from Shahid Beheshti Hospital in Kashan. This study was a cross-sectional study. The statistical population consisted of patients with angina pectoris and myocardial infarction admitted to Shahid Beheshti Hospital in Kashan during 2017-2018. Using sequential sampling method and considering inclusion and exclusion criteria, 250 patients were selected. Data were collected using a researcher-made questionnaire including demographic information and some related factors related to drug compliance and the Morisky (2008) questionnaire. Finally, the data were analyzed using Chi-square test by the SPSS software. The results showed that 58% of the patients had moderate and 36.4% had poor adherence and only 5.6% of the patients had high adherence to their drug regimen. There was a significant relationship between drug adherence rate and education level (P=0.007), diagnosis of disease (P=0.008), dependence on others (P=0.001), sensory problems (hearing-vision) (P=0.002), cognitive problems (memory) (P=0.016), and concerns about drug complications (P=0.0016). According to the results of this study, the medication adherence rate in the studied patients was mostly poor to moderate, and the adherence rate with the medication regimen was related with some factors.
