Key result
Coronary tortuosity is linked to lower CAD incidence despite independently causing myocardial ischemia.
Why the study?
Scarce data is available on the clinical profile of patients with coronary tortuosity and its relation with coronary artery disease.
Is coronary tortuosity associated with coronary artery disease and specific clinical profiles in patients undergoing angiography?
Case-Control (n=224)
Is coronary tortuosity associated with coronary artery disease and specific clinical profiles in patients undergoing angiography?
p-value: p=0.02
Coronary tortuosity is more common in females and hypertensives, is negatively correlated with CAD, but can independently lead to myocardial ischemia.
CT prevalence of 20% in angiography patients; leaves open its relation to CAD presence or severity.
Background: Coronary tortuosity is a common angiographic finding. Scarce data is available on clinical profile of patients with coronary tortuosity (CT) and its relation with coronary artery disease (CAD). Method: A total 224 patients undergoing angiography for suspected CAD were included in the study. CT was defined by the presence of ≥3 consecutive bends of > 45 degree measured at end-diastole in an epicardial artery ≥2 mm in diameter. CT was present in 45(20.08%) patients in the study and another 45 patients without CT was randomly selected as control (NCT group). Clinical profile of CT and NCT group was compared. Results: Incidence of CT was significantly higher in females (p=0.000) and hypertensives (p=0.001) patients. CT was most commonly seen in Left circumflex coronary artery. Incidence of CAD was significantly lower in CT group as compare to NCT group (0.02). Risk factors for CAD was associated with reduced incidence of CT. Majority (88.46%) patient with CT without CAD presented with chronic stable angina out of which (65.21%) had an objective evidence of myocardial ischemia. Conclusion: CT is more commonly seen females and hypertensive patients. It has negative correlation with CAD. Risk factors of CAD do not predict CT. CT itself can lead to myocardial ischemia.

Gupta et al. (2018) conducted a case-control in Suspected coronary artery disease (n=224). Coronary tortuosity vs. No coronary tortuosity was evaluated on Incidence of coronary artery disease (p=0.02). Coronary tortuosity was associated with a significantly lower incidence of coronary artery disease compared to controls (P=0.02), although it can independently lead to myocardial ischemia.
