The Assessment of Adherence to the Treatment Regimen in Patients with Percutaneous Coronary Intervention

Background: Cardiovascular diseases are one of the world’s most important causes of mortality. Despite the reduction in mortality, these patients are forced to adherence is a particular therapeutic regimen to prevent further complications. This cross-sectional study was conducted on 110 patients four to six weeks following Percutaneous Coronary Intervention (PCI). Methods: The questionnaire involved seven areas: attention in treatment, willingness to participate in treatment, ability to adapt, treatment integration with life, adherence to treatment, commitment to treatment, and doubt in implementing treatment. Results: Findings showed that the standardized mean score of total treatment adherence was 91.39. According to the results, gender, age, marital status, place of residence, underlying disease, smoking, use of cardiac drugs, patient condition and the number of vessels involved did not affect the score of treatment adherence (p>0.05). Further analysis revealed that with increasing hospitalization days, treatment adherence increases (p<0.05). Conclusion: The present survey indicated that patients’ treatment adherence was favorable. Based on the findings, treatment adherence, one of the fundamental factors for reducing the mortality rate of patients undergoing PCI, is satisfaction level. Further investigations are highly recommended to consider other risk factors for reducing the mortality rates in these patients.
