Correlation of Microvascular Ophthalmic Disease With Macrovascular Coronary Artery Disease in Trinidad — EYE-MI TNT  

Retinal Disease Clinical Trial

Official title:
Correlation of Microvascular Ophthalmic Disease With Macrovascular Coronary Artery Disease in Trinidad: The EYE-MI TNT Study

Clinical Trial Summary

Coronary artery disease (CAD) is the leading cause of death in Trinidad and Tobago. Early detection and management can help improve morbidity and mortality. Retinal artery microvascular disease has been shown to directly correlate with coronary artery disease. Retinal artery calibre screening via the Optic Coherence Tomography (OCT) will provide a non-invasive method of diagnosing CAD.

Clinical Trial Description

Cardiovascular disease is the number one cause of death in Trinidad and Tobago. There has been a 20.4% increase in cardiovascular deaths from 2007 to 2017(1). Prevention of non-communicable diseases decreases the burden and progression to cardiovascular disease. Prevention of death from cardiovascular disease can also be decreased by early detection, intervention and appropriate management of coronary artery disease. Due to the burden of the cost of health care on the economy of Trinidad and Tobago, patients are required to go on a waitlist to receive specialist medical investigation such as a coronary angiogram. This investigation is only offered at one public health facility in Trinidad and Tobago, the Eric Williams Medical Sciences Complex. Coronary artery disease is graded by a scoring system, the SYNTAX score, which is calculated based on the assessment of the complexity of coronary artery disease by coronary angiography (2). In a study done on 173 patients- the EYE-MI study, patients with the lowest retinal vascular density had a higher SYNTAX score, indicating a direct correlation between retinal artery calibre and the severity of coronary artery disease (3). Retinal artery calibre is assessed using the Optical Coherence Tomography. It is a relatively affordable non-invasive test performed by an Ophthalmologist that allows three dimensional imaging of the retinal vasculature. It is recommended by the American Association of Ophthalmologist for assessing retinal disease (4). This test is not available in the public health care system in Trinidad and Tobago. In a country with a Human Capital Index of 0.61 (5), and cardiovascular disease being the number one cause of death, a cheaper non-invasive tool to screen for coronary artery disease would be of benefit to the population. We postulate that there is a direct correlation between the retinal artery calibre assessed by the Optical Coherence Tomography and the severity of coronary artery disease. There are not many studies assessing this relationship and this study will promote further avenues for research into this correlation. ;
