Key result
Post-MVR compliance decreases at 12 months but favors female, middle-aged, married, and educated patients.
Why the study?
The study was conducted to evaluate and compare the influence of gender, age, family status, education level, and frequency of INR monitoring on compliance in patients after mitral valve replacement with mechanical prostheses over time.
What demographic and clinical factors influence patient compliance after mitral valve replacement with mechanical prostheses?
Observational (n=260)
What demographic and clinical factors influence patient compliance after mitral valve replacement with mechanical prostheses?
Patient compliance after mechanical mitral valve replacement decreases over 12 months and is lower in men, young or elderly patients, unmarried individuals, and those with less frequent INR monitoring.

Compliance declines may warrant targeted INR monitoring in lower-adherence subgroups after mechanical MVR; leaves open whether interventions improve long-term outcomes.
Objective: to study and compare the influence of such factors as: gender, age, family status, level of education and the frequency of determination of the international normalized ratio (INR) on the compliance of patients after mitral valve replacement (MC) with mechanical prostheses in dynamics - after 6 and 12 months. Materials and methods: it were analyzed data of 260 patients after MC prosthetics with mechanical bicuspid prostheses. The Morisky-Green test was used to assess compliance.Results: the most committed to treatment were female, middle-aged persons with secondary specialized and higher education, as well as married persons. Among patients who monitored INR on a monthly basis, the percentage of compliant patients was higher compared to patients where this indicator was determined less than once a month. The dynamics of a decrease in the number of compliant patients after 12 months of follow-up was established. Conclusions: the data obtained indicate the need to carry out more active work on the formation of compliance with «vulnerable» categories of patients: with men, with elderly and young patients, with persons with secondary education, unmarried. The revealed tendency to decrease compliance after 12 months, regardless of the studied factor, indicates the importance of maintaining compliance in the long-term postoperative period. Also, the data obtained indicate the presence of a relationship between the multiplicity of INR control and compliance.

Markova et al. (2022) conducted an observational in Mitral valve replacement with mechanical prostheses (n=260). Sociodemographic factors and INR monitoring frequency was evaluated on Treatment compliance assessed by the Morisky-Green test. Patient compliance after mitral valve replacement was highest among females, middle-aged, married, and highly educated individuals, but decreased overall at 12 months.
