Abstract

Background: Coronary vessel dominance, defined by the coronary artery that supplies the posterior descending artery (PDA) and posterolateral branches, influences the relative contribution of the different coronary arteries to the total left ventricular blood flow.  This work aimed to evaluate the prognostic value of coronary arterial dominance post primary PCI, during hospital stay and at 3-month follow-up, which include; cardiac mortality, heart failure, non-fatal myocardial infarction, re-vascularization, stroke/TIA and re-admission for ACS.

Methods: This prospective observational study included 100 patients a with STEMI who underwent successful primary percutaneous coronary intervention with TIMI III flow and without procedural complications. Patients were divided into 3 groups according to coronary dominance: Right coronary dominant group (RCD), left coronary dominant group (LCD) and balanced coronary dominant group (BCD). All patients were subjected to transthoracic echocardiogram and coronary angiography and Primary percutaneous coronary intervention. 

Results: Ticagrelor and clopidogrel during hospital stay and on hospital discharge were significantly used more with RCA group than LCX group and LCX & RCA group (P=0.021, 0.012), (P=0.018, 0.014), respectively. GPIIB/IIIA was significantly more used during hospital stay with RCA group than LCX group and LCX & RCA group(P=0.014). Nitrates was significantly used more on hospital discharge with RCA group than LCX group and LCX & RCA group (P<0.001).   

Conclusions: Coronary arterial domi¬nance showed significant prognostic value in cases of myocardial Infarction after PCI, heart failure in LCX cases and in revascularization, heart failure, and stroke/TIA cases in RCA. Further, readmission for ACS was the most common outcome in all groups after 3-months follow-up. 

Introduction

Coronary vessel dominance, defined by the coronary artery that supplies the posterior descending artery (PDA) and posterolateral branches, influences the relative contribution of the different coronary arteries to the total left ventricular blood flow [1]. 

In a right-dominant circulation, the right coronary artery (RCA) supplies the posterior portion of the inter-ventricu­lar septum and gives off the posterior descending artery. This contrasts with a left-dominant circulation, in which the left cir­cumflex (LCX) artery supplies this territory. In a co-dominant circulation, supply of the posterior inter-ventricular septum is shared by the RCA and LCX. The prevalence of left dominance is 8%, whereas co-dominance has 7% population prevalence, [1] and right dominant system has a reported prevalence of 82–89% [2, 3]. In patients with a left dominant system, 60% of the left ventricular myocardium is supplied by the posterolateral branches and PDA originating from the LCx [4]. This less well-balanced coronary circulation might have a negative influence on prognosis of patients with coronary artery disease (CAD). Currently, the prognostic importance of coronary vessel dominance in patients presenting with first ST-segment elevation myocardial infarction (STEMI) remains uncertain [4].

Variations in coronary circulation are common, particularly with regard to the supply of the posterior wall of the left ventricle. While a right dominant coronary artery is most commonly observed, a left dominant system is considered to be a normal variant of the coronary anatomy [2, 3].  At present, little is known about the clinical relevance of this anatomical variation. A study screening 1620 post-mortem angiograms showed that the prevalence of a left dominant system decreased with age, [3] suggesting a higher death rate among patients with a left dominant coronary artery system. An explanation could be that a larger amount of myocardium is at risk in these patients, resulting in more extensive myocardial infarction in case of a left coronary artery occlusion.

However, there is limited knowledge about the relation between coronary dominance patterns and the risk of various adverse clini­cal events that can occur following percutaneous coronary interven­tions (PCI). Previously, Goldberg et al. [5] showed that the presence of a left dominant system was associated with an increased mortality in patients presenting with acute coronary syndrome (ACS). Accordingly, a more recent registry (the Cath PCI registry) observed higher in-hospital mortality after PCI in patients with a left dominant system [1].

Left ventricular (LV) systolic dysfunction and remodeling have been strongly associated with short- and long-term outcomes of patients with STEMI undergoing primary percutaneous coronary intervention (PCI) [6]. Independent correlates of LV systolic dysfunction and remodelling after STEMI include infarct size, heart rate, and severity of coronary artery disease [7-9]. LV dysfunction affected by coronary arterial dominance, as Yip et al[10] showed that a left dominant system was independently predictive of failed reperfusion in patients with LCx artery infarction. The effect of coronary arterial dominance on LV dysfunction and remodelling at follow-up is unclear [5].

The aim of this work was to evaluate the prognostic value of coronary arterial domi­nance post primary PCI, during hospital stay and at 3-month follow-up, which include; cardiac mortality, heart failure, non-fatal myocardial infarction, re-vascularization, stroke/TIA and re-admission for ACS.

Patients and Methods

This prospective observational study included 100 patients a with STEMI who underwent successful primary percutaneous coronary intervention with TIMI III flow and without procedural complications. Exclusion criteria: Prior coronary artery bypass graft to assess the effect of specific culprit vessel site without confounding by by-pass grafts, previous PCI, usuccessful PCI, cardiogenic shock, STEMI with mechanical complication, left main disease >50%, previous myocardial infarction, valvular heart disease, atrial dysrhythmias, end stage renal failure and abnormal liver function. Patients were  divided into 3 groups according to coronary dominance: Right coronary dominant group, (RCD), left coronary dominant group, (LCD) and balanced coronary dominant group, (BCD).

Transthoracic echocardiogram

2-dimensional echocardiography was performed within 48 hours of admission and at 3-month follow-up. Routine Images were obtained at rest. M-mode, 2-dimensional, and Doppler images acquired. Systolic LV function was assessed. LV ejection fraction (LVEF) was calculated (226). Subsequently, the LV was divided into 16 segments to calculate the wall motion score index (WMSI). Every segment was individually assessed and scored based on its motion and systolic thickening as the following: Normokinesis or hyperkinesis =1, Hypokinesis =2, Akinesis =3, Dyskinesis =4 and Aneurysm = 5. WMSI was calculated as the sum of the segment scores divided by the number of segments visualized (226)WMSI classified as the following: 1 is norma1, 1-1.49 is mild impairment, 1.5-1.99 is moderate impairment and  ≥ 2 is severe impairment.

Coronary angiography and Primary percutaneous coronary intervention

The images of the coronary angiography and PCI were obtained according to standardized angiographic projections [11]. During the analysis coronary vessel dominance, the culprit vessel and culprit lesion and severity of CAD were recorded. The extent of CAD was expressed as the presence of one-, two- or three-vessel disease (stenosis causing ≥ 70 % luminal narrowing). Complete revascularization were defined as treating all present significant coronary artery stenosis (≥ 70 % luminal narrowing) during primary PCI or during secondary revascularization before discharge. Angiographic success of PCI was defined as TIMI III flow with residual stenosis below 0%.

Angiographic assessment of Coronary arterial dominance [12]

Coronary arterial dominance was defined according to the following definition: Right coronary dominant if the PDA and at least one posterolateral branches originating from the right coronary artery (RCA). Left coronary dominant if the PDA and the posterolateral branches originating from the LCx. Balanced coronary dominant if the PDA originating from the RCA in combination with posterolateral branches originating from the LCx artery [12].

The Brain Natriuretic Peptide

Test used: We used Alere Triage® BNP Test is a rapid, point of care fluorescence immunoassay designed to be used with the Alere Triage® Meters for the quantitative measurement of B-type natriuretic peptide (BNP) in EDTA anticoagulated whole blood or plasma specimens. The test procedure involves the addition of several drops of an EDTA

Statistical Analysis

All variables were expressed as mean ± standard deviation. The Chi-square test was used to analyse categorical variables. Student's t test and analysis of variance were used for continuous variables. Univariate and multivariate analyses were performed to identify independent predictors of no-premature atherosclerosis. Statistical analysis were made using SPSS 19.0. A P value <0>

Results  

 All patient’s characteristics, ECG STEMI were insignificantly different among the studied groups. There was insignificant difference in approach of catheterization (femoral or radial) between the three groups. [Error! Not a valid bookmark self-reference.]

Discussion:

 Coronary artery dominance is associated with the extent of CAD with incidence and all‑cause mortality of AMI but not with atherosclerotic involvement. Research has suggested difference in post‑PCI outcome and mortality of patients with acute coronary syndrome (ACS) undergoing PCI based on their coronary artery dominance. Coronary artery dominance is also associated with 30‑day mortality and early reinfarction after STEMI [13-15].

In our study, there was an insignificant difference CKMB between the three groups.

Our results were not in consistent with [16]. They observed that median CK‑MB were significantly different, and the highest values were observed in LD group (195.79 U/L, respectively). Larger included sample size and ethnic consideration can explain this contradiction. However, [17] found that the peak level of CK-MB was significantly higher in LCX group than in RCA group. This difference could be justified by the large recruited sample size and excluding patients with codominant LCX & RCA. 

In our study, there was insignificant difference in approach of catheterization (femoral or radial) between the three groups. Our findings were in agreement with [18] who observed no significant difference in catheterization (femoral or radial artery) between the right- or co-dominant anatomy (RD group) and those with left dominant anatomy (LD group).

In our study, there is insignificant difference in type of stent and wire (soft and DES) and its diameter, length, and number of stents used among the three groups. 

In consistent with our results, [19] assessed two-year follow-up data of 1,387 patients from the randomized TWENTE trial. Based on the origin of the posterior descending coronary artery, coronary circulation was cat­egorised into left and non-left dominance (i.e., right and balanced). This was in line with [16] results; as no significant difference was detected in terms of stent type, size, and number among right, left and Co‑dominant groups. 

Moreover, [20] reported no significant difference between all studied group in stent length, number and diameter. 

In the present study, EF before discharge was significantly different among the three groups (P <0>

Comparable to our findings, [17] found that EF was higher in RCA group than LCX group. 

In our results, EF after 3 months was significantly different among the three groups (P =0.007). It was significantly higher in RCA group than LCX group and LCX & RCA group and was significantly higher in LCX group than LCX & RCA group.

Similarly, [21] conducted a study to compare the outcome of patients with CX versus right coronary artery (RCA) related STEMI. A total of 1683 consecutive patients with STEMI were studied. Patients who lacked STEMI were also included if they had persistent chest pain with signs of ischaemia or regional wall motion abnormalities on echocardiography. Coronary angioplasty was performed according to standard procedures. After the intervention, all patients received aspirin and clopidogrel or ticlopidine. The results showed that LVEF was significantly higher in patients with RCA- related MI treated by primary percutaneous intervention (PCI) when compared to LCX- related MI. Further, [17] results demonstrated that the left ventricular ejection fraction was notably lower in LCX group than RCA group after 30-Day. This difference could be related to the variety in duration of follow up.

In contrast, [20] found no significant difference in lower left ventricular ejection fraction after 3 months by both 2D and 3D echocardiography in patients with left dominant, right coronary dominant, and balanced coronary dominant groups. 

Our findings were in line with [22] study which included one hundred fifty consecutive patients with acute inferior wall STEMI. Patients were divided into two groups according to the infarct related artery (LCX vs. RCA). All patients underwent routine adjunctive angioplasty after TLT during the index hospitalization and clinical characteristics and outcomes were compared. There was lower left ventricular ejection fraction (LVEF) (p= 0.01) in patients with LCX occlusion compared with RCA. 

In the present study, EF after 3 months was significantly higher than before discharge in the groups (p <0>, [20] found that after 3 months follow-up a significantly lower left ventricular ejection fraction at admission was observed by both 2D and 3D echocardiography in patients with a left dominant system.

In our study, regarding in-hospital clinical outcome, the most common outcomes in the LCX group were myocardial Infarction after PCI and heart failure each occurred in 3 (10.34%) patients, the most common outcomes in the RCA group were revascularization, heart failure, and stroke/TIA each occurred in 3 (4.29%) patients, the most common outcome in the LCX & RCA group was Stroke/TIA occurred in 3 (27%) patients.

In consistent with our results, [17] study results demonstrated that the frequency of advanced congestive heart failure was remarkably higher in group LCX than in RCA group (all P < 0>

Furthermore, [23] conducted a prospective, observational, nonrandomized study and enrolled 200 consecutive patients with inferior wall STEMI. All patients were treated with emergency percutaneous coronary intervention during hospitalization and clinical characteristics and outcomes were compared. Group 1 included 100 patients presented with acute inferior wall STEMI caused by RCA occlusion and Group 2 included 100 patients presented with acute inferior wall STEMI caused by LCX occlusion. Total primary outcome in their study was higher in LCX group (p=0.048) that may be related to heart failure, stroke and bleeding which were more than RCA group. 

Limitations: The study population was of limited size and the number of sites included in our registry. We only included patients with acute STEMI who were treated with primary PCI, which may have influenced the prevalence of CD pattern. Our findings must be interpreted in the context of acute STEMI treated with primary PCI, and they do not necessarily apply to all patients with acute STEMI.

Conclusion

Coronary arterial domi­nance showed significant prognostic value in cases of myocardial Infarction after PCI, heart failure in LCX cases and in revascularization, heart failure, and stroke/TIA cases in RCA. Further, readmission for ACS was the most common outcome in all groups after 3-months follow-up.

"We recently published an article entitled “Influence of beta-Cyclodextrins upon the Degradation of Carbofuran Derivatives under Alkaline Conditions" in the Journal of “Pesticides and Biofertilizers” to show that the cyclodextrins protect the carbamates increasing their half-life time in the presence of basic conditions This will be very helpful to understand carbofuran behaviour in the analytical, agro-environmental and food areas. We greatly appreciated the interaction with the editor and the editorial team; we were particularly well accompanied during the course of the revision process, since all various steps towards publication were short and without delay".

I am very pleased to serve as EBM of the journal, I hope many years of my experience in stem cells can help the journal from one way or another. As we know, stem cells hold great potential for regenerative medicine, which are mostly used to promote the repair response of diseased, dysfunctional or injured tissue using stem cells or their derivatives. I think Stem Cell Research and Therapeutics International is a great platform to publish and share the understanding towards the biology and translational or clinical application of stem cells.
