Insights

Patients with type D personality show lower adherence to therapy. This behavioral pattern may be linked to poorer outcomes in cardiovascular disease patients, highlighting a need for targeted interventions.

Area of Science:

  • Cardiology
  • Psychology
  • Behavioral Science

Background:

  • Cardiovascular diseases (CVDs) are a leading cause of mortality worldwide.
  • Patient adherence to therapy is crucial for managing chronic conditions like ischemic heart disease and hypertension.
  • Type D personality, characterized by negative affectivity and social inhibition, may influence health behaviors.

Purpose of the Study:

  • To investigate the relationship between type D personality and therapy adherence in patients with stable ischemic heart disease and arterial hypertension.
  • To determine if type D personality is an independent predictor of poor treatment compliance.

Main Methods:

  • A cohort of 308 patients with stable ischemic heart disease and arterial hypertension were assessed.
  • Patients were categorized into groups with (n=84) and without (n=224) type D personality using the DS-14 questionnaire.
  • Treatment adherence was evaluated using the S.V. Davydov method and the Morisky-Green test.

Main Results:

  • Patients with type D personality exhibited significantly lower adherence to treatment compared to those without (48% vs. 39%, p<0.05).
  • Conversely, higher adherence rates were more prevalent in the group without type D personality (19% vs. 11%, p<0.003).
  • Type D personality was independently associated with lower compliance (odds ratio 3.21, p=0.02).

Conclusions:

  • Type D personality is linked to reduced therapy adherence in cardiological patients.
  • This behavioral characteristic may represent a significant factor contributing to unfavorable prognoses in individuals with cardiovascular diseases.
  • Interventions targeting psychological factors like type D personality could improve treatment adherence and patient outcomes.
