National survey on the secondary preventive measures for coronary artery disease among interventional cardiologists: a report from the Japanese Association of Cardiovascular Intervention and Therapeutics

Insights from recent clinical trial testing revascularization strategies have interested interventional cardiologists in optimal medical therapy and secondary prevention modalities. As no large-scale survey has been recently conducted, this report presents the results of a nationwide survey on interventionists’ concerns regarding secondary prevention after percutaneous coronary intervention (PCI) and discusses medical support system needs in Japan. A questionnaire to assess the status and challenges of secondary prevention interventions by interventional cardiologists during outpatient visits was supplied to Cardiovascular Interventional Technology (CVIT)-certificated hospitals. This was answered by representative cardiologists of each hospital and comprised three queries: (1) the necessity of outpatient cardiac rehabilitation to promote post-PCI lifestyle guidance; (2) the feasibility of providing lifestyle guidance; and (3) the barriers to lifestyle guidance, during outpatient visits. Questions 1 and 2 were answered using a 5-point Likert scale. Survey responses were received from 391 hospitals (54.9% of 712 CVIT-certificated facilities). For Question 1, 327 hospitals (84.1%) answered “agree”, and 386 hospitals (98.7%) answered “agree” or “somewhat agree”. For Question 2, 10% of hospitals answered “agree”, and "agree" and "somewhat agree" amounted to less than 50%. For Question 3, 83.5% of the facilities answered lack of time as the major reason). The next reasons included an early reverse referral to family doctors after PCI, and a lack of managerial advantage (60% and 40% of the hospitals, respectively). In conclusion, interventionists are concerned about secondary prevention for their patients. The issues clarified in the survey will be important for developing next-generation secondary prevention systems.
