Surgical revascularization of a rare type IV dual left anterior descending artery—a case report

Background Type IV dual left anterior descending artery (LAD) is a rare congenital coronary anomaly. Though benign with most of the patients being asymptomatic, knowledge of its existence and identification during coronary angiography is important during coronary interventions and surgical revascularization. Case presentation We present a rare case of type IV dual left anterior descending artery (LAD) with anomalous origin of one of the two vessels from the right coronary sinus. A 49-year-old female presented with inferior wall infarction and she underwent coronary angiography. Coronary angiogram showed triple vessel coronary artery disease. This rare variant of dual LAD was identified and was confirmed intra-operatively. The patient underwent coronary revascularization with grafts to both the LAD systems. Conclusions Proper assessment of the angiogram and knowledge of the coronary anomalies is required during surgical revascularization and percutaneous coronary interventions. This rare anomaly can be missed due to the anomalous origin of the LAD from the right coronary sinus. The identification of the dual LAD and grafting of both the LAD systems is required to achieve complete revascularization.

Clopidogrel resistance is common in patients undergoing vascular and coronary interventions

Objectives “Clopidogrel resistance,” also defined as heightened platelet reactivity (HPR) while on clopidogrel therapy, may lead to a sub-optimal antiplatelet effect and a potential thrombotic event. There is limited literature addressing the prevalence of HPR in a large cohort of patients receiving either coronary or endovascular interventions. Methods In a large integrated healthcare system, patients with a P2Y12 reaction units (PRU) test were identified. HPR was defined as a PRU ≥ 200 during clopidogrel therapy. Vascular and coronary interventions were identified utilizing CPT codes, HPR prevalence was calculated, and Fischer’s exact test was used to determine significance. Results From an initial cohort of 2,405,957 patients (October 2014 to January 2020), we identified 3301 patients with PRU tests administered. Of these, 1789 tests had a PRU ≥ 200 (HPR overall prevalence, 54%). We then identified 1195 patients who underwent either an endovascular or coronary procedure and had a PRU measurement. This corresponded to 935 coronary and 260 endovascular interventions. In the coronary cohort, the HPR prevalence was 54% (503/935). In the vascular cohort, the HPR prevalence was 53% (137/260); there was no difference between cohorts in HPR prevalence ( p = 0.78). Conclusion “Clopidogrel resistance” or HPR was found to be present in nearly half of patients with cardiovascular disease undergoing intervention. Our data suggest HPR is more common in the cardiovascular patient population than previously appreciated. Evaluating patients for HPR is both inexpensive ($25) and rapid (< 10 min). Future randomized studies are warranted to determine whether HPR has a clinically detectable effect on revascularization outcomes.

The effect of sexual counseling on depression, anxiety, stress, sexual knowledge and sexual quality of life in men who have undergone invasive coronary interventions: An RCT

Background: Sexual dysfunctions are common in men with ischemic heart disease, especially in men undergoing therapeutic interventions. Objective: This study intended to assess the effect of counseling on depression, anxiety, stress, sexual knowledge and sexual quality of life in men after invasive coronary interventions in the post catheterization department of Kashan Shahid Beheshti Hospital during 2018. Materials and Methods: The study population consisted of 54 male participants who had undergone an invasive coronary intervention. The intervention group received counseling and the control group underwent the standard ward routine. Data were collected using the depression anxiety stress scales, Abraham’s sexual quality of life, and the Yi-Hung Sexual Knowledge questionnaires before discharge and also two months later. Results: Within two months, the intervention group’s mean score of sexual knowledge significantly increased, compared with the control group, from 12.37 to 14.81 (p ≤ 0.001). The intervention group’s mean score of sexual quality of life also significantly increased, compared with the control group, from 48.2 to 60.7 (p ≤ 0.001). Moreover, the mean anxiety score changed in the intervention group from 11.18 to 5.25, again a significant difference compared with the control group (p = 0.01). But, the differences in the depression and stress scores were not significant. Conclusion: Our findings suggest that sexual counseling may improve sexual knowledge, sexual quality of life and anxiety in men following invasive coronary intervention, but might not reduce their stress or depression. Further studies are needed to confirm these findings.
