Acute Myocardial Infarction in Cancer Patients

March 12, 2025 updated by: Joo Myung Lee, Samsung Medical Center

Risk and Clinical Outcomes of Acute Myocardial Infarction in Patients With Cancer: A Nationwide Study

Using national health insurance service database, current study aim to evaluate the risk and prognosis of acute myocardial infarction in cancer patients and to find the optimal treatment strategy for acute myocardial infarction that can improve long-term prognosis.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will be conducted using Korean National Health Insurance Service database. Patients who were diagnosed with cancer from 2002 to 2021 will be included in the study. Using the selected patients, current study will analyze the incidence and prognosis of acute myocardial infarction in cancer patients and the prognosis according to the treatment method for acute myocardial infarction will be compared. Primary outcome will be all-cause death. Secondary outcomes will be myocardial infarction, revascularization, hospitalization for heart failure, stroke, and clinically relevant bleeding.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients who were diagnosed with cancer from 2002 to 2021 will be considered in the study. Among these patients, those diagnosed with acute myocardial infarction after the diagnosis with cancer will be included in the study.

Description

Inclusion Criteria:

  • Patients diagnosed with cancer between 2002 and 2021
  • Patients who were diagnosed with acute myocardial infarction after cancer diagnosis

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
All-cause death
Time Frame: 2-years after diagnosis of acute myocardial infarction
All-cause death which was obtained from death certification collected by Statistics Korea at the Ministry of Strategy and Finance of South Korea
2-years after diagnosis of acute myocardial infarction

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Myocardial infarction
Time Frame: 2-years after diagnosis of acute myocardial infarction
Myocardial infarction is defined as presence of the diagnostic codes (ICD-10 I21, I22) in the primary position during hospitalization
2-years after diagnosis of acute myocardial infarction
Revascularization
Time Frame: 2-years after diagnosis of acute myocardial infarction
Percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG)
2-years after diagnosis of acute myocardial infarction
Hospitalization for heart failure
Time Frame: 2-years after diagnosis of acute myocardial infarction
Heart failure events requiring hospitalization defined as presence of the diagnostic codes (I110, I130, I132, I255, I420, I425-I429, I43, I50, I971) in the primary position during hospitalization
2-years after diagnosis of acute myocardial infarction
Stroke
Time Frame: 2-years after diagnosis of acute myocardial infarction
Stroke is defined as ischemic stroke (ICD-10 I63, I64) or intracranial hemorrhage (ICD-10 I60-62), combined with the codes of diagnostic brain imaging.
2-years after diagnosis of acute myocardial infarction
Clinically relevant bleeding
Time Frame: 2-years after diagnosis of acute myocardial infarction
Bleeding requiring hospitalization or transfusion
2-years after diagnosis of acute myocardial infarction
