Key result
Post-operative cardiac valve surgery patients had 95.9% medication dose adherence and 76.7% monthly PT/INR testing, though 21.9% reported bleeding events.
Why the study?
Adherence to recommended diagnostic and therapeutic regimens after cardiac valve repair or replacement is crucial for reducing associated complications, warranting evaluation of prevailing symptoms and patient compliance.

Although medication and follow-up adherence were high among post-cardiac valve replacement patients, substantial clinical and instructional gaps persist regarding dietary vitamin K intake, timely PT/INR monitoring, and post-operative symptoms including bleeding.
Introduction: Adherence to recommended diagnostic & therapeutic regimen by patients with cardiac valve repair/replacement plays crucial role in declining the rate of associated complications. Aims & Objectives: A cross-sectional study was aimed to evaluate patients for prevailing signs & symptoms and their level of adherence towards diagnostic & therapeutic regimen. Materials & Methods: Present study included 73 post-surgical adult patients with repair/ replacement of any of the four valves with either mechanical or bioprosthetic valve visiting out-patient department during their scheduled follow-up. Seven self-developed tools were utilized to collect information regarding demographic, clinical, surgical profile, existing clinical manifestations and adherence towards recommended medications, PT/INR testing & follow-up visits, diet, exercise/activity, personal & wound-care. Results: About 47.9% participants had undergone mitral valve surgery followed by double valve replacement (34.2%) with mostly mechanical replacement (84.9%) followed by bioprosthetic (13.7%). About 8 participants were currently indulged into smoking/alcohol consumption. Blood thinning medications were prescribed to 94.5% patients. Mean PT & INR value was 22.7± 11.2 seconds & 2.4 ± 1.5 respectively and 76.7% patients underwent PT/INR testing monthly. 95.9% & 94.5% of patients adhered to recommended medication’s dose & scheduled time respectively. Compliance rate improved from 87.7% to 94.5% for the second scheduled visit. Approximately 21.9% reported bleeding events. About 30.1% participants were consuming more than the recommended amount of green leafy vegetables & 30.1% and 38.4% were regularly consuming fatty foods and red meat respectively. Conclusion: Present study recognized numerous ‘‘clinical & instructional gaps’’ in terms of non-compliance by few patients.
