Key result

TEE LMCA peak diastolic velocity above ~85 cm/s predicts high-risk SYNTAX scores in MI patients.

Why the study?

The study aimed to correlate transthoracic and transesophageal echocardiography parameters with SYNTAX score categories in patients with coronary artery disease.

Do trans-thoracic and transesophageal echocardiography parameters accurately predict SYNTAX score categories in patients with coronary artery disease?

Key Points

The study aims to evaluate the correlation between echocardiographic parameters and SYNTAX score categories in patients with myocardial infarction.
Conducted a cross-sectional study in a tertiary medical facility.
Included patients with acute myocardial infarction and other coronary syndromes.
Evaluated echocardiographic parameters against SYNTAX score categories using receiver operating characteristic analysis.
The TELPD parameter showed 72.4% sensitivity and 71.8% specificity for high SYNTAX score category (3).
TELD had 77.8% sensitivity and 70.9% specificity for low SYNTAX score category (1).
TERD demonstrated 71.1% sensitivity and 63.6% specificity for low SYNTAX score category (1).

Structured PICO

Do trans-thoracic and transesophageal echocardiography parameters accurately predict SYNTAX score categories in patients with coronary artery disease?

P

Population

100 Indian patients with acute myocardial infarction, unstable angina, chronic coronary syndrome, or clinically and hemodynamically stable patients

I

Intervention

Trans-thoracic echocardiography and transesophageal echocardiography (TOE)

O

Outcome

Predictive ability of trans-thoracic echocardiography/TOE parameters for SYNTAX score categories 3 (high risk) and 1 (low risk)surrogate

Implication

Transesophageal echocardiography parameters, such as left main coronary artery peak diastolic velocity and diameter, can reliably predict SYNTAX score categories in patients with coronary artery disease.

Abstract

Context: Atherosclerosis is caused by the interplay of multiple risk factors, including traditional ones and nontraditional factors. Aortic atherosclerosis can lead to cerebral embolism (stroke or transient ischemic attack), and peripheral and visceral embolism. Techniques such as trans-thoracic echocardiography and transesophageal echocardiography (TOE) are noninvasive techniques used to evaluate arterial atherosclerosis. Our study aimed to correlate the trans-thoracic echocardiography/TOE parameters with the synergy between percutaneous coronary intervention with Taxus and cardiac surgery (SYNTAX) score (SS) categories. Materials and Methods: Our research was a cross-sectional study conducted in the cardiology inpatient department of a tertiary medical facility over 1 year. This research entailed patients undergoing acute myocardial infarction, unstable angina, chronic coronary syndrome, as well as patients who had been clinically and hemodynamically stable. Results: In our study, a total of 100 patients were included. The receiver operating characteristics curve was computed for all the trans-thoracic echocardiography/TOE parameters’ predictive ability for SS categories 3 (high risk) and 1 (low risk). The trans thoracic echocardiography (TEE) parameter (TELPD = TEE left main coronary artery peak diastolic velocity in cm per second (LMCA)) was found to be successful in indicating SS category 3 (high) reliably, with 72.4% sensitivity and 71.8% specificity for a cut-off value of 84.5. The Two TEE parameters were found to be successful in indicating SS category 1 (low) reliably, the first one was TELD (TEE_LMCA, diameter in mm) with 77.8% reactivity and 70.9% precision for a cut-off value of 3.81, the second one was TERD (TEE_right coronary artery, diameter in mm) with 71.1% sensitivity and 63.6% specificity for a cut-off value of 2.72. Conclusion: This study shows the use of TOE in evaluating atherosclerosis and the angiographic relationship between it and coronary artery disease (CAD), providing insightful information for better diagnostic and prognostic assessment in patients with CAD.
