Abstract
Coronary dominance describes the anatomic variation of coronary arterial supply, notably as it relates to perfusion of the inferior cardiac territories. Differences in the development and outcome in select disease states between coronary dominance patterns are increasingly recognized. In particular, observational studies have identified higher prevalence of poor outcomes in left coronary dominance in the setting of ischemic, conduction, and valvular disease. In this qualitative literature review, we summarize anatomic, physiologic, and clinical implications of differences in coronary dominance to highlight current understanding and gaps in the literature that should warrant further studies.

Meda JR, Kusima HL, Magitta NF. Angiographic characteristics of coronary artery disease in patients undergoing diagnostic coronary angiography at a tertiary hospital in Tanzania. BMC Cardiovasc Disord 2024; 24:125. [PMID: 38408906 PMCID: PMC10898171 DOI: 10.1186/s12872-024-03773-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 02/06/2024] [Indexed: 02/28/2024] Open
Abstract
BACKGROUND Coronary artery disease (CAD) is an important cause of global burden of disease. There is a paucity of data on the burden and risk factors for CAD in sub-Saharan Africa (SSA), despite the rising trends in the shared risk factors across regions. The recent introduction of cardiac catheterization laboratory services in SSA could shed light on the burden of CAD in the region. We aimed to assess the angiographic characteristics among patients undergoing diagnostic coronary angiography (CAG) at a single tertiary care hospital in Tanzania. METHODS This study was a retrospective chart review. A total of 728 patients ≥ 18 years of age who underwent CAG from January 2020 to December 2022 were recruited into the study. Basic demographic variables, risk factors and clinical characteristics including CAG findings were obtained from the registry. In addition, CAG images were retrieved for assessment of angiographic features. The luminal vessel stenosis was assessed based on eyeballing and the degree of obstruction was agreed by two independent and experienced cardiologists. The coronary stenosis of ≥ 50% was considered significant for obstructive CAD. The study was approved by the local ethics committee. RESULTS Of patients who were recruited into the study, 384 (52.23%) were female. The study participants had a mean age of 59.46 ± 10.83 standard deviation (SD) and mean body mass index (BMI) of 31.18 kg/m2. The prevalence of CAD of any degree was estimated at 24.43% (34.18% in male, 15.50% in female), while that of obstructive CAD was 18.27%. Forty six percent of those with obstructive CAD had multiple vessel disease (MVD). Nearly 77% of patients were found to have ≥ 50-70% luminal stenosis and while those with ≥ 70% luminal coronary artery stenosis constituted 56.65%. Right coronary artery (RCA) was the most commonly affected vessel, accounting for 36.84% when any vessel disease or 56% when single vessel disease were considered. Being 65 years or older and comorbidity with type 2 diabetes (T2D) were independent risk factors for developing CAD. CONCLUSION There is a high prevalence of obstructive CAD among patients undergoing diagnostic CAG in Tanzania, with male gender preponderance and increasingly higher in older age, often with severe disease. A large, prospective study is needed to provide epidemiological and clinical data for developing a locally-relevant cardio-preventive strategy for CAD intervention in Tanzania.

Int J Gen Med 2023; 16:2867-2876.

Abstract
Purpose The values of European Society of Cardiology (ESC) criteria and dual antiplatelet therapy (DAPT) score in the stratification of ischemic risk were assessed in this study. Methods A total of 489 patients with acute coronary syndrome who received DAPT at discharge between June 2020 and August 2020 were enrolled. The primary endpoint was the occurrence of major adverse cardiovascular events (MACE), which included recurrent ACS or unplanned revascularization, all-cause death, or ischemic stroke during a 27-month follow-up period. Results Patients with ESC-defined high-risk showed a significantly higher risk of MACE (HR 2.75, 95% CI 1.78-4.25), all-cause death (HR 2.49, 95% CI 1.14-5.43), and recurrent ACS or unplanned revascularization (HR 2.80, 95% CI 1.57-4.99) than those with ESC-defined low/medium-risk during follow-up. The results of landmark analysis showed that patients in the high-risk group had a significantly higher risk of MACE (HR 2.80,95 CI% 1.57-4.97), recurrent ACS or unplanned revascularization (HR 3.19,95 CI% 1.47-6.93) within one year, and a higher risk of MACE (HR 2.69,95 CI% 1.38-5.23) after one year. There was no significant difference in the incidence of MACE between patients with a DAPT score ≥2 and a DAPT score <2. The C-indices of ESC criteria and DAPT score for prediction of MACE were 0.63 (95% CI 0.57-0.70) and 0.54 (95% CI 0.48-0.61), respectively. The predictive value of ESC criteria for MACE was better than the DAPT score according to the DeLong test (z-statistic=2.30, P=0.020). Conclusion Patients with ESC-defined high-risk had a higher risk of MACE compared to those with ESC-defined low/medium-risk. The discriminant ability of the ESC criteria was better than the DAPT score for MACE. The ESC criteria demonstrated moderate discriminatory capacity of MACE in ACS patients treated with DAPT.

Abstract
For several decades, coronary artery bypass grafting has been regarded as the standard choice of revascularization for significant left main coronary artery (LMCA) disease. However, in conjunction with remarkable advancement of device technology and adjunctive pharmacology, percutaneous coronary intervention (PCI) offers a more expeditious approach with rapid recovery and is a safe and effective alternative in appropriately selected patients with LMCA disease. Several landmark randomized clinical trials showed that PCI with drug-eluting stents for LMCA disease is a safe option with similar long-term survival rates to coronary artery bypass grafting surgery, especially in those with low and intermediate anatomic risk. Although it is expected that the updated evidence from recent randomized clinical trials will determine the next guidelines for the foreseeable future, there are still unresolved and unmet issues of LMCA revascularization and PCI strategy. This paper provides a comprehensive review on the evolution and an update on the management of LMCA disease. With advancements in PCI, clinical outcomes after left main PCI have progressively improved. Unmet needs still exist between clinical practice and the current evidence for left main PCI. Better decision making of revascularization choice and PCI optimization should be emphasized to improve outcomes of LMCA disease. Further research will provide further evidence to resolve conflicting issues on left main PCI.

Atherogenic index of plasma for non-diabetic, coronary artery disease patients after percutaneous coronary intervention: a prospective study of the long-term outcomes in China. Cardiovasc Diabetol 2022; 21:29. [PMID: 35193553 PMCID: PMC8864872 DOI: 10.1186/s12933-022-01459-y] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Accepted: 02/03/2022] [Indexed: 12/31/2022] Open
Abstract
Background Non-diabetic coronary artery disease (CAD) patients are thought to encounter metabolic dysfunction and while these changes may be imperceptible to the patient they probably influence outcomes. At present, there is no system to support patients sensing these subtle changes, nor is there an established model for prognoses. The Atherogenic Index of Plasma (AIP) index has already proven useful for atherosclerosis although further research is needed, especially for those without hyperglycemia. Methods This is a prospective study of 5538 non-diabetic CAD patients who had received percutaneous coronary intervention (PCI). Participants were assigned to one of three groups according to their AIP index. High AIP index cases were then compared to low index patients according to major adverse cardiac events (MACE). Restricted cubic spline (RCS) analysis was also conducted to investigate interrelations between AIP index levels and hazard ratios (HR) for MACEs. Results Patients with a high AIP index encountered metabolic dysfunction compared to those with a low AIP index i.e., higher Body Mass Index (BMI), Total Cholesterol (TC), Triglycerides (TG), and uric acid as well as lower HDL-C. Each of the aforementioned interrelations were significant with p values of less than 0.001. There was also a significant increase in the number of MACEs in the high AIP index group compared to the low AIP index group (HR: 1.37, 95% CI 1.04–1.81; p = 0.025). A J-shaped RCS curve highlighted a change in the HR after the 0.18 juncture (HR per SD: 1.20, 95% CI 0.96–1.50). Further subgroup analysis supported the main findings, all with HRs greater than one. Conclusion The AIP index could be used in prognostics for non-diabetic CAD patients 2 years after PCI. The relationship between hazard ratio and the AIP index appears to be J-shaped. Although, further multi-center studies designed for non-diabetic patients with potential metabolic dysfunction should be conducted to determine the value of the AIP index.
