Our results showed that the coronary slow flow phenomenon could not impair the longitudinal LV systolic and diastolic functions.

Background:The coronary slow flow phenomenon (CSFP) is the slow passage of the angiographic contrast agent to the distal portion of the coronary artery in the absence of significant stenosis. We evaluated the left atrial (LA) function in patients with the CSFP using two-dimensional speckle-tracking echocardiography (2DSTE).Methods:The LA function was compared through 2DSTE between 36 patients with the CSFP and 36 participants with a normal coronary flow. The two groups were matched for age, sex, hypertension, diabetes mellitus, and the left ventricular function.Results:There were no statistically significant differences between the CSFP group and the control group regarding longitudinal systolic strain, early and late diastolic strains, and the strain rate of the LA myocardium.Conclusions:The LA function as evaluated with 2DSTE was not different between the CSFP group and the normal coronary flow group when they were matched for age, sex, hypertension, diabetes, and the left ventricular function.

Background: Electrocardiography (ECG) changes after subarachnoid hemorrhage (SAH) are well described. However, concurrent myocardial infarction (MI) and SAH are rarely reported, and its management remains a dilemma. We report a patient with traumatic SAH concurrent with acute MI that managed successfully by endovascular intervention and dual antiplatelet therapy. Case Description: A 47-year-old man was admitted to the emergency department with a complaint of severe headache. Diffuse SAH, with a Hunt and Hess score of 5, was noticed. ECG showed ST elevation in anterior leads, and cardiac troponin became positive. On brain computed tomography angiogram, a 6 mm anterior communicating artery aneurysm was seen. Considering the possibility of MI and SAH simultaneously, endovascular obliteration of the aneurysm was done, and then, the patient received dual antiplatelet medications until coronary angiography was done. Coronary angiography revealed normal epicardial coronary arteries. The patient was discharged with a Glasgow Coma Scale score of 15 and was visited 2 months after discharge without any new episodes of intracranial hemorrhage with a modified Rankin scale score of 2. Conclusion: Cerebral aneurysm coiling could be considered as the first choice of treatment in the case of acute MI with hemodynamic stability, before carrying out cardiac endovascular intervention or antiplatelet medication to reduce the risk of rebleeding from a brain aneurysm.

CSFP was not associated with tissue Doppler echocardiographic and 2DSTE-derived indices of RV systolic and diastolic function.
