MYOCARDIAL BRIDGE TYPE AND PROXIMAL STENOSIS RELATIONSHIPS IN HYPERTENSIVE PATIENTS

Abstract

This study aimed to study the predisposing factors of hypertension as well as the relationships
between myocardial bridge type and proximal stenosis in hypertensive patients.
A total of 200 MB patients at El-Azhar Hospital were selected for this quantitative study.
Among them 80 patients with normal blood pressure (BP) and stenosis were excluded. Most of the
patients had come to the hospital with complaints for chest tightness/pain and underwent MDCT scan
due to suspicions of coronary artery disease and they were diagnosed with MB. Among remaining 120
patients, 7 5 were (62.5%) males and 55 were (45.83%) females, with the average age of patientsat
68.02 ± 12.65.
Data of each individual patient’s age, sex, BP, blood cholesterol level, diabetes status, bridge
length, bridge type, artery involved, and stenosis were all recorded. Patients consent was taken prior to
the MDCT scan andoral consent from the ethical committee was taken to carry out this research.
This study concluded that, the main predisposing risk factors for hypertension includes , male is
more susceptable than female, hypercholesterol, diabetes, smoking. Also, there wasstrong evidence of
atherosclerosisin the proximal part of the artery, while the bridged andtherefore tunneled artery showed
no atherosclerosis. Theresults of this research, therefore, indicate that there isno significant relationship
between the MB and stenosisin hypertensive patients.
