Coronary Slow Flow Phenomenon

Coronary Slow Flow Phenomenon (CSFP) is characterized by the slow flow of contrast in one or more epicardial coronary vessels without evidence of coronary artery stenosis during coronary angiography procedures. CSFP is fairly common at the time of elective angiography with an incidence of around 7% and accounts for about 4% of hospitalized unstable angina cases. Coronary angiography is currently still the only effective way to detect CSFP, but this procedure is an invasive procedure with high costs, there is a risk of allergy to contrast. Electrocardiography (ECG), as a widely available, inexpensive, and simple modality is felt to be an attractive alternative in early detection of this abnormality. The ECG parameters on CSFP discussed in this study include; p-wave dispersion, QT interval dispersion, QRS intrinsic (Tpeak-Tenddeflection duration), and QRS fragmentation. Further studies are needed on the ECG image in CSFP so that in the future ECG can be a cheaper and non-invasive diagnostic modality for CSFP compared to coronary angiography.

Coronary Slow Flow Phenomenon

BACKGROUND: The presence of gene polymorphisms in the renin-angiotensin-aldosterone system associated with an impaired endothelial function that causes atherosclerosis and also myocardial fibrosis such as the polymorphism of the angiotensin-converting enzyme gene and the angiotensin I receptor (AT1R) gene. AIM: This research was aimed to explore the role of AT1R A1166C gene polymorphism in the incidence of coronary slow flow phenomenon (CSFP) in the Malay population, South Sumatra, Indonesia. METHODS: This study is a comparative analysis using a case-control study design to analyze the effect of the AT1R A1166C gene polymorphism on the incidence of slow flow phenomenon in patients undergoing elective coronary angiography at Mohammad Hoesin Hospital Palembang, Indonesia. Examination of AT1R gene polymorphism was carried out with several steps starting from deoxyribonucleic acid extraction, polymerase chain reaction process, followed by restriction fragment length polymorphism stages with Ddel restriction enzymes and visualization. RESULTS: Thirty-two patients participated in these study-baseline characteristics between homogeneous coronary regular flow groups and homogeneous coronary slow flow groups. There is no difference between genotype distribution, allele frequency, and genotype between the CSFP and the coronary standard flow group. CONCLUSION: There is no influence of AT1R A1166C gene polymorphism on the CSFP in patients undergoing coronary angiography.

Aim. To study the structural and functional status of coronary blood flow in patients with acute coronary syndrome with nonobstructive coronary arteries using multispiral computed tomography (MSCT) and single photon emission tomography (SPECT) and to compare data of MSCT and invasive coronary angiography (ICA).Material and Methods. This study is a non-randomized, open-label, controlled clinical trial. The study is registered on ClinicalTrials.gov. The inclusion criteria are listed on the site. All patients underwent CT and SPECT.Results. The study included 14 patients with MINOCA; the group comprised predominantly women (n=11, 78.6%); the average age was 61.1±14 years. The risk according to GRACE (Global Registry of Acute Coronary Events) risk score was moderate in 8 patients (57%) and high in 5 patients (35.7%). 85.7% of patients were admitted to hospital within the first six hours from onset of diseases. Three patients (21.4%) received thrombolytic therapy and it was effective in two of them (14%). Risk factors included hypertension (64.2%), dyslipidemia (50%), and burdened history (71.4). According to the results of invasive coronary angiography, intact coronary arteries were detected in 9 patients (64.3%); 5 patients (35.7%) had stenosis up to 50%. Coronary slow-flow phenomenon (TIMI 2) was detected in 11 patients (78.6%) including 8 patients (57.1%) who had coronary slow-flow phenomenon and intact coronary arteries. Severe coronary spasm was registered in 1 patient (7.1%) in the group with ST segment elevation acute coronary syndrome (STE ACS). According to MSCT data, the proportion of patients with intact coronary arteries decreased from 7 (50%) to 5 patients (35.7%) whereas the proportion of patients with nonstenosing atherosclerosis increased from 7 (50%) to 9 patients (64.3%). Twenty six atherosclerotic plaques were detected including eccentric (76%), circular (11.5%), and semi-circular plaques (11.5%). In regard to morphological structure, the atherosclerotic plaques were calcified (59.5%), mostly calcified (7.7%), and soft (29%). Normal myocardial perfusion (Summed Stress Score (SSS) and Summed Rest Score (SRS) <4) was detected in two patients (14.3%); 12 patients (85%) had transitory perfusion defects. The median score values were 7.5 (4; 13) for SSS, 4.7 (1.0; 9.0) for SRS, and 4.7 (3.0; 8.0) for SDS.Conclusion. The introduction of MCTA and SPECT into the algorithm of the examination of patients with acute myocardial infarction and non-obstructive atherosclerosis of the coronary arteries was safe when additionally used during index hospitalization. These approaches provided new information about the structure and function of the coronary arteries. These data provide rationale for further study using a larger group of patients to determine a prognostic significance of detecting the atherosclerotic plaques with the signs of instability in this patient category.

Abstract Purpose: In this study, we aimed to investigate the relationship between high triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C) ratio and coronary slow-flow phenomenon (CSFP) in patients undergoing elective coronary angiography for suspected coronary artery disease. Methods: This prospective study included a total of 84 CSFP patients and 83 controls with normal coronary flow, as evidenced by coronary angiography. The Thrombolysis in Myocardial Infarction (TIMI) frame count (TFC) was used to measure the coronary blood flow velocity. The lipid profiles were analyzed and TG/HDL-C ratio were calculated dividing absolute TG levels by absolute HDL-C levels in peripheral blood. Results: The median TG/HDL-C ratio was higher in the CSFP group than the control group (3.4 [2.6 to 4.9] vs. 2.3 [1.8 to 3], respectively; p<0.001). The multivariate logistic regression analysis revealed that TG/HDL-C ratio was an independent predictor of CSFP (odds ratio [OR]: 1.78, 95% confidence interval [CI]: 1.59-2.32; p=0.001) and TG/HDL-C ratio was positively correlated with the TFC in the CSFP group ( r =0.311, p<0.001). The area under the receiver operating characteristic curve of TG/HDL-C for the diagnosis of CSFP was 0.73 (95% CI: 0.65-0.81; p<0.001). If a cut-off value of 2.75 was used, higher levels of TG/HDL-C ratio could predict the presence of CSFP with 72% sensitivity and 71% specificity. Conclusion: Our study results suggest that TG/HDL-C ratio is associated with CSFP and may be a useful biomarker for predicting CSFP and its severity.
