Objectives: To determine the association of hyperuricemia with the presence and severity of coronary artery disease in patients undergoing coronary angiography. Methodology: This case control study was carried out in the Department of Cardiology, Chaudhary Pervaiz Elahi Institute of Cardiology, Multan for six months. Total number of 292  patients (146 cases with coronary artery disease and 146 controls with normal coronary arteries) having age 40-60 years of both genders were included in this study. Coronary angiography was performed using standard angiographic techniques. After undergoing coronary angiography, patients with 50% luminal stenosis or more in any one of the coronary arteries were labeled case group. Patients with normal coronaries or less than 50% luminal stenosis in any one of the coronary vessels were taken as control group. Serum uric acid was advised and value was noted along with the basic demographic data and established risk factors of coronary artery disease. Results: Mean age was 50.79±6.08 years. Mean serum uric acid was 7.54±3.60 mg/dl. Hyperuricemia was diagnosed in 94 (64.40%) patients with significant CAD (case group) and in only 59 (40.40%) in control group. The odds ratio was 2.66 (95% CI 1.66 to 7.28) with p-value of <0.001. Triple vessel disease was diagnosed in 66.7% patients with hyperuricemia and in only 33.3% patients without hyperuricemia [OR 4.0 (2.09-7.64), p-value <0.001]. Conclusion: There is a significant association between the presence and severity of coronary artery disease with hyperuricemia.

Background and Aims: The use of coronary angiography in diagnosing coronary artery disease is limited by its invasive property. In the other hand correct interpretation of tread mill test data and its use as a key diagnostic modality also has been a problem. The study was thus aimed to see the diagnostic accuracy of treadmill test to rule out coronary artery disease.Methods: We included all the patients who had positive tread mill stress test and underwent coronary angiography and were subsequently analyzed for presence of coronary artery disease.Results: A total of 303 patients were included with 119 males and 184 females with mean age of 53.6±10.5 yrs and 51.7±8.6 yrs respectively. Normal coronaries was seen in 114(54.0%), borderline lesion in 29 (13.7%) and significant lesion in 68 (32.2%) with 48(22.7%) having single vessel disease, 29(13.7%) double vessel disease and 14(6.6%) triple vessel disease. Coronary artery diseases was highest among diabetics (57.7%, OR 1.72 (95 % CI: 0.92 to 3.20), p value-0.08).Similarly the risk of coronary artery disease was significantly highest among patient with ≥2 risk factor (OR: 8.10,95 % CI: 4.96 to 13.24, P < 0.0001). Gender distribution showed that coronary artery disease was significantly higher in males than females (53% vs 35% respectively, OR: 2.08, 95 % CI: 1.30 to 3.32, p value-0.002).Conclusion: The value of tread mill test to predict coronary artery disease is highest in patients with two or more risk factor especially in those with diabetes with significance increased among males.

Backgrounds: Hyperuricemia has not yet been established as cardiovascular risk factor. We aimed to study the angiographic severity in patients with coronary artery disease (CAD) and hyperuricemia.Materials and Methods: In this observational cross-sectional study we measured serum uric acid level in 82 patients of CAD who underwent coronary angiography in catheterisation laboratory of our Institution. Severity of CAD was determined on the basis of Gensini score, number of diseased vessels, critical lesions and total occlusions.Results: The prevalence of hyperuricemia in patients with CAD was 42.68% in our study. Hyperuricemia was associated with higher Gensini score (33.33±10.64 vs. 22.90±6.75, p value <0.001), number of critical lesions (1.03±0.84 vs. 0.63±0.72, p value 0.031), total occlusions (0.67±0.47 vs. 0.37±0.48, p value 0.007) and dyslipidemia (63.6% vs. 30.6%, p value 0.003) more frequently compared to normouricemic patients. And also the higher serum uric acid level was correlated with higher Gensini score (beta 0.418, t 4.430, p value <0.001, 95% CI 0.036 and 0.094) and frequent number of total occlusion (beta 0.338, t 3.589, p value 0.001, 95% CI 0.462 and 1.613).Conclusion: Hyperuricemia was associated with higher Gensini score, frequent total occlusions and critical lesions in patients with Coronary Artery Disease compared to patients with normal uric acid level and also it was significantly correlated with higher Gensini score and frequent total occlusions.Asian Journal of Medical Sciences Vol.7(2) 2015 1-4

Lp(a) has been well known as an independent risk factor for coronary artery disease (CAD). TheLPAgene, as it encodes apo(a) of the Lp(a) lipoprotein particle, was associated with increased risk of CAD. The purpose of this study was to analyze the relationship between the polymorphisms ofLPAgene and CAD in Chinese Han population. Five SNPs (rs1367211, rs3127596, rs6415085, rs9347438, and rs9364559) in theLPAgene were genotyped using Sequenom MassARRAY time-of-flight mass spectrometer (TOF) in 560 CAD patients as case group and 531 non-CAD subjects as control group. The numbers of these two groups were from Chinese Han ancestry. The results showed that allele (P=0.046) and genotype (P=0.026) of rs9364559 in theLPAgene was associated with CAD. The frequency of rs9364559 minor allele (G) in case group was obviously higher than that in control group. Results of haplotype analysis showed that 4 haplotypes which contained rs9364559-G were associated with increased risk of CAD in this population. This study explored rs9364559 in theLPAgene may be associated with the pathogenesis of CAD; and the risk of CAD might be higher in the population carrying 4 haplotypes of different blocks in theLPAgene.

Abstract Background Low-attenuation plaque (LAP) with a CT value of less than or equal 30 HU on coronary CT angiography (CCTA) is a marker of high-risk plaque features that leads to future acute coronary syndromes. Perivascular and epicardial adipose tissue (EAT) have been shown to be associated with progression of high-risk coronary plaques through metabolic and inflammatory mechanisms. However, association of EAT with LAP volume in three coronary arteries in subjects with or without visceral obesity remain unclear. Aims This study aimed to investigate the association of EAT volume (EAV) and coronary 3-vessel LAP volume in subjects with or without visceral obesity who underwent CCTA. Methods Patients who underwent CCTA without known coronary artery disease were included in the study (525 patients). Study subjects were classified as having non-obstructive or obstructive coronary artery disease according to the degree of coronary artery stenosis on CCTA. The plaque volume and EAV of the main vessel of the left anterior descending artery, left circumflex artery, and right coronary artery were measured with VINCENT software. Coronary plaque composition was classified as calcified plaque (CP, &gt;150HU), noncalcified plaque (NCP, 30–150HU), and Lap (&lt;30HU). The %LAP volume of the three coronary arteries was classified into quartiles. Multiple logistic regression analysis was used to analyze the factors associated with the %LAP volume. Results Compared with subjects without increase visceral fat, subjects with increased visceral fat had a significantly higher BMI, a greater total plaque volume, a greater total %LAP volume, a greater EAV, and a lower mean CT value of EAT. A significant correlation was observed between EAV and %LAP volume (R=0.24, p&lt;0.001). EAV (odds ratio; 1.83, 95% confidence interval 1.071–3.141, p-value 0.027) and type 2 diabetes mellitus (odds ratio 1.76, 95%confidence interval 1.042–3.000, p-value 0.034) appeared to be independent predictors of %LAP volume (Q4), when adjusted by age, gender, BMI&gt;25 kg/m2, visceral fat &gt;100cm2, LogCRP, coronary artery calcium score&gt;300, and obstructive coronary artery disease requiring revascularization. Conclusion This study suggests that LAP volume, which reflects the high-risk plaques in the three coronary arteries, is associated with EAV in subjects with or without increased visceral fat. Further research is needed whether pharmacological therapeutic intervention enables the prevention of coronary plaque progression and destabilization through the reduction of EAV in patients.

Myocardial Infarction with Non-obstructive Coronary Arteries-MINOCA is a clinical syndrome that encompasses a subgroup of heterogeneous patients who present with myocardial infarction yet do not have any significant coronary artery obstruction on angiogram. From several studies it is understood that MINOCA has a 8.8% prevalence of all Myocardial Infarction (MI) presentations, with no characteristic distinguishing clinical features when compared with MI-CAD( Coronary artery disease), except for patients being younger with a female preponderance & less likely to have hyperlipidemia. The prognosis is extremely variable, depending on the causes of MINOCA. Clinical history, echocardiography, coronary angiography, and left ventriculography represent the first-level diagnostic investigations. Ibrahim Card Med J 2015; 5 (1&2): 61-66

Introduction: Poor physical function impairs fitness and is associated with worse cardiovascular outcomes and all-cause mortality. Arthritis and joint dysfunction limit physical function in coronary artery disease (CAD) patients. Hypothesis: Omega-3 fatty acids (FA) improve physical function in CAD patients through reducing inflammation. Methods: We randomized 249 subjects with stable CAD to 3.6 of omega-3 FA (1.86 g of eicosapentaenoic acid + 1.5 g of docosahexaenoic acid) per day or no omega-3 (control) for one year. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) was used to evaluate pain, stiffness and physical function at baseline and one year follow-up. Inflammation was assessed by total white blood cell (WBC) count and its subsets as well as urine microalbumin-creatinine ratio (MCR). Results: Mean age was 63.0 ± 7.58 years; 17% were women. Controls had worsening stiffness (% Δ = 8.4%; p = 0.036) at 1 year follow-up while those on omega-3 FA had no change (% Δ = 0.4%, p = 0.886 - see Table)(a lower percent change indicates better functioning). Compared to controls, those on omega-3 FA had better physical function (% Δ = 8.5% vs. -2.8%, p = 0.011), and total WOMAC scores (% Δ = 7.8% vs. -2.5%, p = 0.011) and a significant decrease in WBC (% Δ = -3.5 vs. -9.4%; p=0.009) and neutrophils (% Δ = -3.5% vs. -11.6%; p=0.005) at one year follow-up. MCR significantly worsened only in the control group (% Δ = 53.3%, p = 0.037) at one year follow-up (p-value for control vs. omega-3 FAs groups = 0.026). Monocytes were decreased in the omega-3 FAs group at one year compared to baseline (% Δ = -11.1%, p < 0.001) and directly correlated with physical function and total scores (p = 0.033 and p = 0.024, respectively). Conclusions: Omega-3 FAs attenuate worsening of physical function over a one year period in CAD patients possibly mediated through an anti-inflammatory effect. Therefore, omega-3 FA may benefit CAD patients by improving their physical function.

BACKGROUND Coronary artery disease is multifactorial in origin. Coronary artery disease predisposition is attributed to genetic factors also. Many gene polymorphisms are implicated out of which paraoxonase 1 (PON 1) gene is an important one. The product of paraoxonase gene is paraoxonase enzyme which is seen in serum associated with high density lipoprotein (HDL). This enzyme is mainly synthesised by the liver. The protective effect of HDL is attributed to the presence of such enzymes on it. Gln to Arg polymorphism at position 192 confers a risk of developing atherosclerosis and coronary artery disease (CAD). This study is done to assess the genotype distribution of PON 1 gene in CAD patients compared to healthy controls in a population from Kerala. METHODS The case group consists of 100 angiographically proven CAD patients with no history of hypertension, diabetes mellitus, hepatic disease or smoking. The control group had 100 healthy controls from the general population. PON 1 gene was amplified by a polymerase chain reaction (PCR) technique already reported and restriction fragment length polymorphism by the restriction enzyme Alwl was done to assess the polymorphism. to assess the polymorphism. RESULTS In this study, the frequency of heterozygous genotype QR was 86 % in control and 76 % in cases. Though there was no significant difference in allele distribution of Q or R, RR genotype was significantly higher in the case group ( 2 = 8.82; p value = .012). With binary logistic regression model, adjusting for age and sex, RR genotype is independently associated with CHD. Adjusted odds ratio of RR was 5.24 with 95 % confidence interval (CI) 1.41 - 19.47 for developing CHD (p < 0.05). CONCLUSIONS The RR genotype is more frequently seen in CAD patients than in controls. The QR genotype is more frequent than QQ or RR in both cases and controls. KEYWORDS Coronary Artery Disease, Paraoxonase, Gene Polymorphism

Background. Coronary artery ectasia (CAE) occurs in 0.3 to 5.3% of patients undergoing coronary angiography. TIMI frame count (TFC) is an index of coronary flow that correlates with flow velocity. In ectasia patients, there is delayed coronary flow with increased TFC.Methods.We evaluated angiograms of 789 patients for presence of CAE, coronary artery disease (CAD), and Markis type of CAE. We measured ectasia size and length and their correlation with TFC in ectatic right coronary arteries (RCA) of patients with CAE and CAD.Results.30 patients had CAE (3.8%). Of these 16.7% had isolated CAE, while 83.87% had CAE and CAD. Among CAE and CAD patients, the RCA was most involved (70.4%), and Markis type IV CAE was the commonest (64%). In isolated CAE, the RCA, LAD, and LCx were equally involved (33.3%). Patients with CAE and CAD had significantly higher TFC compared to controls,P=0.035. There was a positive correlation of moderate strength, between ectasia size and TFC,r(17) = 0.598,P=0.007. Ectasia length was not significantly correlated with TFC, rho (17) = 0.334,P=0.163.Conclusion.Among patients undergoing angiography, CAE has a prevalence of 3.8% and Markis type IV is the commonest. Larger ectasias are associated with slower coronary flow.
