Diagnosis of Myocardial Ischemia With MCG Using SPECT as a Reference Standard

August 19, 2024 updated by: Qilu Hospital of Shandong University

Identification of Myocardial Ischemia With Magnetocardiography Using Single Photon Emission Computed Tomography (SPECT) as a Reference Standard

This is a prospective clinical study aiming to investigate the efficacy of Magnetocardiography (MCG) in detecting myocardial ischemia in patients of a suspected non-ST-elevation-acute coronary syndrome (NSTE-ACS) by using Single photon emission computed tomography (SPECT) as the gold standard for determining the presence and severity of myocardial ischemia.

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.

Study Type

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Chest pain patients who have CAG showing <70% stenosis at the most severe site or CTA showing non-severe stenosis

Description

Inclusion Criteria:

  • Age 18 years or older;
  • Patients with symptoms of myocardial ischemia such as angina pectoris, who have CAG showing <70% stenosis at the most severe site or CTA showing non-severe stenosis
  • Signed informed consent.

Exclusion Criteria:

  • Patients with absolute or relative contraindications to SPECT-loaded myocardial perfusion, including acute myocardial infarction within 48 hours, significant left main coronary artery stenosis, bronchial asthma, and adenosine injection allergy;
  • Patients with Non-ischemic dilated cardiomyopathy, or hypertrophic cardiomyopathy, or moderate or severe valvular disease;
  • Patients with Hemodynamic instability (systolic blood pressure<90 mmHg, or who requires vasoactive drugs), or patients with tachyarrhythmia, Ⅱdegree atrioventricular block and above that have not returned to normal;
  • Patients who have severe renal abnormality with eGFR <30 ml/min, or patients who are on dialysis;
  • Patients with malignant tumors with predicted survival of less than 1 year;
  • Pregnant or breastfeeding women;
  • Patients who are unable to enter the MCG device, who are unable to perform MCG examination due to interference from metal implants or other reasons, or who are deemed by the investigators to be unsuitable for enrollment.

Design Details

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
Efficacy of MCG to detect myocardial ischemia using SPECT as a reference standard.
Time Frame: from the date of enrollment until the date of discharge, up to 30 days
Sensitivity, specificity, and area under the ROC curve are performed for assessing the efficacy.
from the date of enrollment until the date of discharge, up to 30 days

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
Efficacy of MCG to detect myocardial ischemia in patients with coronary stenosis <50% (Ischemia with no obstructive coronary artery, INOCA)
Time Frame: from the date of enrollment until the date of discharge, up to 30 days
Sensitivity, specificity, and area under the ROC curve are performed for assessing the efficacy.
from the date of enrollment until the date of discharge, up to 30 days

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 12, 2024

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
