About this trial
• Aim of the work: To examine the relationship between collateral circulation and the frontal QRS-T angle in patients with chronic total occlusion (CTO)
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients undergoing diagnostic coronary angiography due to stable angina persisting for a minimum duration of three months.
Patients diagnosed with total occlusion in at least one coronary artery, assessed to have chronic total occlusion (CTO) based on clinical and angiographic findings.
Disqualifiers
Patients presenting with malignancies, atrial fibrillation, connective tissue disorders, hepatic failure, or renal failure.
A documented history of cardiac pacemaker implantation, prior bypass surgeries, or surgical valve replacements.
Congenital heart anomalies.
Patients receiving pharmacological interventions that affect ventricular repolarization (other than beta-adrenergic antagonists).
Trial population
The study population consists of adult patients presenting to the cardiology department who have experienced stable angina for a minimum of three months and are subsequently diagnosed with a chronic total occlusion (CTO) in at least one coronary artery during routine diagnostic coronary angiography.

Treatments tested in this trial
12-lead Electrocardiogram (ECG) and Coronary Angiography
Diagnostic testA 12-lead ECG is performed to calculate the frontal QRS-T angle, and coronary angiography is performed to evaluate the coronary collateral circulation using the Rentrop Classification.
Treatment groups
100 Participants
are divided into 2 treatment groupsGroup A: Increased QRS-T Angle1 intervention
Group B: Normal QRS-T Angle1 intervention
