Insights

Coronary heart disease patients show poor adherence to enhanced external counter pulsation (EECP) after hospital discharge. Improving patient understanding and offering flexible scheduling are key to enhancing EECP treatment adherence.

Area of Science:

  • Cardiology
  • Rehabilitation Medicine
  • Public Health

Background:

  • Enhanced external counter pulsation (EECP) is part of cardiac rehabilitation for coronary heart disease (CHD) in China.
  • Short hospital stays and unclear post-discharge adherence limit EECP effectiveness.
  • This study addresses the low adherence to EECP post-discharge in CHD patients.

Purpose of the Study:

  • To investigate adherence rates to EECP among CHD patients after discharge.
  • To identify factors influencing EECP adherence in this population.
  • To explore reasons for non-adherence to EECP treatment post-discharge.

Main Methods:

  • A retrospective mixed-methods study combining quantitative and qualitative approaches.
  • Quantitative analysis of 1,304 CHD patients treated with EECP (March 2020 - August 2021).
  • Qualitative in-depth interviews with non-adherent patients to explore dropout reasons.

Main Results:

  • Only 24.23% of patients adhered to EECP post-discharge.
  • Predictors of non-adherence include shorter disease duration, lower education, longer travel distance, older age, female gender, and angina pectoris.
  • Higher family income was associated with better adherence.

Conclusions:

  • Post-discharge adherence to EECP for CHD is significantly low.
  • Interventions like educational materials (brochures, videos) are needed to improve understanding of EECP importance.
  • Flexible scheduling (off-hours, weekends) may improve adherence, particularly for younger patients.

Acute Coronary Syndrome V: Nursing Management

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...
