About

This study is medical record review and questionnaire survey on the economic burden on Chinese patients with myocardial infarction accompanied by dyslipidemia in a real-world environment.

The primary objective of the study is to investigate the economic burden of disease on patients and the factors influencing it, which may include the mode of treatment for dyslipidemia, drugs for the secondary prevention of myocardial infarction, the outcome of treatment for dyslipidemia, adverse drug reactions and major cardiovascular events.

The secondary objectives of the study include:

1. patient compliance with medication;
2. health-related quality of life (HRQoL) in patients.

Full description

This study is a multicenter retrospective cohort survey study using a cross-sectional design. It is conducted mainly by a medical record review, questionnaire survey and medical examination to collect data.

Enrollment: 900 estimated patients

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients were hospitalized because of acute myocardial infarction in a study hospital between January 1, 2016 and December 31, 2016. If a patient was hospitalized because of multiple occurrences of myocardial infarction during this period, his/her initial hospitalization because of myocardial infarction will be considered index hospitalization. Patients undergo continuous screening in a reverse order based on time.
• Patients did not die during "index hospitalization".
• Patients had Low-density lipoprotein≥1.8 mmol/L shown by the first measurement of blood lipids or were using lipid-regulating drugs at the first measurement of blood lipids during "index hospitalization" in 2016.
• Patients consent to participate in this study and grant informed consent; or the family of a patient who died before telephone screening consents to provide relevant information and grant informed consent.

Exclusion criteria

• Patients participated in interventional clinical trials after "index hospitalization".
• Patients had paid <5 visits to the outpatient clinics of a study hospital within one year since discharge after "index hospitalization" (if patients who have died within one year since discharge after "index hospitalization").
• There is a barrier to communication with a patient or his/her family (if the patient has died); a patient or his/her family (if the patient has died) cannot correctly understand and answer questions normally.
