The Relationship

Background: Coronary artery disease (CAD) is predicted to be the most common cause of death and disability globally by 2020. In Bangladesh, for better management of coronary artery disease and to reduce the burden of acute coronary events patients with non ST elevated acute coronary syndrome (NSTE–ACS) should be focused. B-type natriuretic peptide (BNP) can be suggested as a tool to predict severity of coronary atherosclerotic lesion even with normal left ventricular (LV) function and thus to categorize the patients for appropriate referral and invasive evaluation.Aims: This study is designed to assess the relationship between level of BNP and severity of coronary artery disease assessed with SYNTAX score in NSTE-ACS patients with normal LV function. Methods: This cross sectional observational study was conducted at UCC, BSMMU during the period of May 2014 to April 2015 among the patients with non ST elevated myocardial infarction (NSTEMI) and unstable angina. 116 patients were enrolled by non-random purposive sampling who was admitted for coronary angiogram. All the data were recorded in structured questionnaire including details of medical history, coronary risk factors and physical findings. In NSTE-ACS patients with normal LV function venous blood samples were collected for BNP and later SYNTAX scoring was assessed during coronary angiogram. The relationship between level of BNP and SYNTAX score in patients with both UA and NSTE-MI was assessed statistically to evaluate the validity of BNP as a tool to predict severity of coronary atherosclerotic lesions among the patients with NSTE-ACS.Results: The mean age was 57.84±8.82 years. Among the 116 patients, highest frequency of patients was in the age group 51-60 years 55(47.4%) .In which 88(75.9%) were male. Male:Female ratio is 3.1:1.The percentage of risk factors was higher in NSTEMI group and difference with UA was statistically significant (p <0.05). Serum BNP in UA 64.9±13.07 and in NSTEMI 107.2±11.53. The mean difference of serum BNP between two groups is statistically significant. In UA group the SYNTAX score was found 13.2±11.1 and in NSTEMI 19.9±13.5 which is statistically significant. In UA group maximum patients were found two vessel disease and in NSTEMI maximum patients in three vessel disease. 70.0% of patients of three vessel disease had e” 80pg/ml of BNP. The association is statistically significant (p< 0.05). Higher the level of BNP reflect higher the vessel involvement and SYNTAX score irrespective of UA and NSTEMI.Conclusion: Our study reveals BNP is a candidate for entry into the setting of principal risk scores. Our findings indicate that the level of BNP may reflect the severity of ischemic insult even when irreversible injury and systolic dysfunction have not occurred.University Heart Journal Vol. 12, No. 1, January 2016; 17-22

Abstract Background Takotsubo cardiomyopathy (TCM) is diagnosed in 1–2% of all patients presenting with acute coronary syndrome (ACS). Clinical differences in individuals presenting with either the typical (apical) or atypical (midventricular, basal and focal) localization of left ventricular contraction abnormalities are not well understood. Methods We retrospectively analyzed 102 consecutive patients diagnosed with TCM based on clinical presentation, coronary angiography, and laevocardiography. Patients with different contraction abnormality patterns were compared regarding sex, clinical presentation, trigger for TCM, LV-function and LV enddiastolic pressure (LVEDP) as well as coronary artery disease. Results Of all TCM 102 patients, 69 (68%) presented with the typical pattern of apical contraction abnormality. 33 patients (32%) had an atypical pattern: 22 (22%) with the midventricular type, 2 (2%) with the basal type and 9 (9%) with a focal type. There was no difference in sex distribution among the different types of TCM (female: typical 86% vs atypical 85% p=0.83). Presentation as a ST-elevation ACS was more common in patients with atypical compared to typical TCM (21% vs. 17%; p=0.85), but without statistical significance. Cardiogenic shock (typical 6% vs atypical 3%; p=0.91) as well as intra-hospital death (typical 3% vs atypical 3%; p=0.56) were rare in both types. A trigger was not more common in patients with typical TCM (58% vs atypical 55%; p=0.91). The trigger was more often physical in typical (73%) and atypical TCM (78%) than psychological, but the distribution did not differ between the two types (p=0.92). 83.6% of the patients showed an impaired LV-EF. Median LV-EF in patients with typical TCM (35% (IQR 25–40)) tended to be lower than in patients with atypical TCM (40% (IQR 25–40); p=0.63; LV-EF ≤30% typical TCM 45% vs. atypical TCM 39%; p=0.75). In 72% (73/102) of the patients the LVEDP was determined. In 75% (55/73) the LVEDP was elevated (>15mmHg). LVEDP tended to be more often elevated in patients with typical TCM (83% vs. atypical 52%; p=0.11). Extent of coronary artery disease did not differ in the different types of TCM. Coronary stenosis >50% was rare (typical TCM 20% vs atypical TCM 9%; p=0.26), whereas exclusion of coronary artery disease was common in both types (typical TCM 71%; atypical TCM 76%; p=0.79). Conclusion While an apical contraction anomaly is the most common type of presentation in TCM, atypical contraction patterns are found in 32% of the patients. Overall, psychological triggers are not found as frequently in TCM as previously described. Patients with typical and atypical TCM do not differ in clinical presentation, LV-EF, LVEDP and extent of coronary artery disease.

Grace Score

The GRACE score constitutes a useful tool for risk stratification in patients with acute coronary syndrome (ACS), while the SYNTAX score determines the complexity of coronary artery disease (CAD). This study sought to correlate these scores and assess the accuracy of the GRACE score in predicting the extent of CAD. A total of 539 patients with ACS undergoing coronary angiography were included in this analysis. The patients were classified into those with a SYNTAX score < 33 and a SYNTAX score ≥ 33. Spearman’s correlation and receiver operator characteristic analysis were conducted to investigate the role of the GRACE score as a predictor of the SYNTAX score. There was a significantly positive correlation between the SYNTAX and the GRACE scores (r = 0.32, p < 0.001). The GRACE score predicted severe CAD (SYNTAX ≥ 33) moderately well (the area under the curve was 0.595 (0.522–0.667)). A GRACE score of 126 was documented as the optimal cut-off for the prediction of a SYNTAX score ≥ 33 (sensitivity = 53.5% and specificity = 66%). Therefore, our study reports a significantly positive correlation between the GRACE and the SYNTAX score in patients with ACS. Notably, NSTEMI patients with a high-risk coronary anatomy have higher calculated GRACE scores. A multidisciplinary approach by a heart team could possibly alter the therapeutic approach and management in patients presenting with ACS and a high calculated GRACE score.

Takotsubo syndrome is an acute and often reversible condition, with initial presentation mimicking acute coronary syndrome. Typically, patients present with left ventricular regional wall motion abnormalities, without a corresponding coronary artery obstruction on angiography. Coexistence of a coronary artery disease is possible and may render the distinction between the two entities particularly challenging. We report the case of a 94-year-old woman with chest pain after an emotional upset and acute myocardial injury. Transthoracic echocardiogram (TTE) revealed a severely reduced left ventricular ejection fraction (LVEF) with apical ballooning. Coronary angiogram showed significant stenosis of the distal left main coronary artery and of the mid-left anterior descending artery, as well as a 30%–50% stenosis of the mid-distal right coronary artery. Revascularisation was deferred and antiplatelet as well as heart failure therapy begun. A repeat TTE 6 days later revealed a quasi-normalised LVEF. Ultimately, percutaneous coronary revascularisation of the left main and left anterior descending artery was performed, with favourable outcome at 6-month follow-up.

Background. Multi-slice computed tomography (MSCT) has been demonstrated as a feasible imaging modality for non-invasive assessment of coronary artery disease and left ventricular (LV) function analysis. Recently, 320-slice systems have become available with 16 cm anatomical coverage allowing prospective image acquisition of the entire heart within a single rotation or heart beat. However, limited data are currently available with these systems. The purpose of the present study therefore was to evaluate the accuracy of 320-slice MSCT in the assessment of global LV function as compared to 2-dimensional (2D) echocardiography. Methods. A head-to-head comparison between 320-slice MSCT and 2D echocardiography was performed in 40 patients (24 male; mean age 61 ± 9 years) with known or suspected coronary artery disease (CAD). During intravenous contrast agent administration, the entire heart was imaged in a single heartbeat, using prospective dose modulation (full dose during 65–85% of R-R interval). The following parameters were used: gantry rotation time 350 ms, tube voltage 120 kV, tube current 300–500mA. LV end-diastolic volumes (LVEDV) and LV end-systolic volumes (LVESV) were determined and the LV ejection fraction (LVEF) was derived. Two-dimensional echocardiography served as the gold standard. Results. Average LVEF was 59% ± 8% (range 31%–77%) as determined on 2D-echocardiography, compared with 61% ± 8% (range 33%–78%) on MSCT. Evaluation of LVEF by linear regression analysis showed a good correlation between MSCT and 2D-echocardiography (r = 0.84; p < 0.001). A close correlation between MSCT and 2D-echocardiography was also demonstrated for the assessment of LVEDV (r = 0.81; p < 0.001) and LVESV (r = 0.89; p < 0.001). At Bland-Altman analysis, mean differences (± SD) of 20.88 ml ± 23.07 ml (p < 0.01) and 6.83 ml ± 13.01 ml (p < 0.01) were observed between MSCT and 2D-echocardiography for LVEDV and LVESV respectively. As a result, LVEF was slightly overestimated with MSCT (1.98% ± 4.54%; p < 0.01). Conclusion. Accurate assessment of LV function and volumes is feasible with 320-slice MSCT in patients with known or suspected CAD.

Objective: Diabetes mellitus, a common metabolic disorder, is often associated with severe coronary artery disease. In this study, we compared the angiographic severity of coronary artery disease in diabetic patients compared with that of non diabetic patients.Methods: This observational study comprised of 102 subjects who had coronary artery disease on coronary angiography in the Department of Cardiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2009 to December 2009. The patients were divided into two groups: one group with 24 (23.5%) diabetic patients and another group with 78 (76.5%) non diabetic patients. Demographic, clinical, laboratory and angiographic data were analyzed and compared between two groups.Results: Mean age±SD of the study subjects was 52.8±9.5 years and 94 (92%) of them were male. Diabetic patients were older (mean age±SD; 57.6±9.5 versus 51.3±9.9 years; p 004), and had higher frequency of hypertension (75% versus 50%, p 0.036), chronic stable angina (71% versus 41%, p 0.018), and lower frequency of smoking (42% versus 67%, p 0.034) and acute coronary syndrome (29% versus 59%; p 0.018) in comparison to non diabetic patients. Left main stem disease (21% versus 5%, p 0.031) and three-vessel disease (50% versus 31%, p 0.094) were more prevalent in diabetic patients. Severe coronary artery stenosis was significantly more present in diabetics than non diabetics (Gensini score, 50.9±29.9 versus 32.6±21.9, p 0.001).Conclusion: Diabetic patients are more likely to have severe and extensive coronary artery disease. Left main stem and triple vessel disease are more commonly seen in diabetic patients compared to non diabetic patients.University Heart Journal Vol. 10, No. 1, January 2014; 13-17

Background : Diabetes mellitus is one of the important risk factors for coronary artery disease. The hemoglobin A1c is used for evaluating glycemic control in diabetic patients. Here, we conducted the study to evaluate the relationship between HbA1c level and severity of coronary artery disease among the hospitalized patients with ACS. Materials & Methods : This cross sectional study was conducted in the department of Cardiology, Ibrahim Cardiac Hospital & Research Institute, Dhaka, Bangladesh from September 2015 to December 2015. Total of one hundred patients were studied and they were grouped on the basis of their glycaemic status. One hundred patients with acute coronary syndrome were enrolled in this study. Out of them fifty were diabetic (HbA1c>6.5%) and rest of were nondiabetics (HbA1c<6.5%) ( group-A and B). Results: Out of one hundred patients fifty eight were male and fourty two were female. Mean age of patients in group-A was 58.54±10.22 years and mean age of patients in group-B was 54.52±13.69 years. Mean age of male and female was 57.72±11.48 years and 54.0±13.08 years respectively. Mean HbA1c of patients in group-A was 11.43±1.43% and group-B was 6.34±0.915%. 38% of group-A and 22% of group-B had triple vessel disease, 26% of group-A and 20% of group- B had double vessel disease and 28% of group-A and 18% of group-B had single vessel disease, and 8% of group-A and 40% of group-B had normal coronary arteries. 48% patients of age group 46-50 in group-A had more incidence in coronary artery disease than other age group which was statistically significant ( p=0.035). 61-75 years age group in group-B patients had coronary artery disease than other age groups which was statistically not significant(p=0.084). Patients of group-A was significantly relation with coronary artery disease (p>.001) and six times greater coronary artery disease than patients of group-B (OR= 6.15, 95% CI for OR =2.074 -18.289). Conclusions: In this way the importance of appropriate glycaemic control has been emphasized in diabetic patients. This study showed the relation between HbA1c levels and the severity of CAD in patient with type-II diabetes mellitus .Our findings demonstrate that elevated HbA1c level was risk factor for severity of coronary artery disease in ACS patients.

Background/Aim. The FINish Diabetes RIsk SCore (FINDRISC) which includes age, body mass index (BMI), waist circumference, physical (in) activity, diet, arterial hypertension, history of high glucose levels, and family history of diabetes, is of a great significance in identifying patients with impaired glucose tolerance and a 10-year risk assessment of developing type 2 diabetes in adults. Due to the fact that the FINDRISC score includes parameters which are risk factors for coronary artery disease (CAD), our aim was to determine a correlation between this score, and some of its parameters respectively, with the severity of angiographically verified CAD in patients with stable angina in two ways: according to the Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score and the number of diseased coronary arteries. Methods. The study included 70 patients with stable angina consecutively admitted to the Clinic of Cardiology, Military Medical Academy, Belgrade. The FINDRISC score was calculated in all the patients immediately prior to angiography. Venous blood samples were collected and inflammatory markers [erythrocyte sedimentation rate (ESR), leucocytes, C-reactive protein (CRP), total cholesterol, HDL cholesterol, triglycerides and fasting glucose] determined. Coronary angiography was performed in order to determine the severity of coronary artery disease according to the SYNTAX score and the number of affected coronary vessels: 1-vessel, 2-vessel or 3-vessel disease (hemodynamically significant stenoses: more than 70% of the blood vessel lumen). The patients were divided into three groups regarding the FINDRISC score: group I: 5-11 points; group II: 12-16 points; group III: 17-22 points. Results. Out of 70 patients (52 men and 18 women) enrolled in this study, 14 had normal coronary angiogram. There was a statistically significant positive correlation between the FINDRISC score and its parameters respectively (age, body mass index-BMI, waist circumference) and the severity of CAD according to the SYNTAX score (p < 0.001) and the number of diseased coronary arteries (p < 0.001). The patients with higher FINDRISC score (groups II and III) had more severe and extensive CAD according to the SYNTAX score than the group I. The odds ratio with 95% confidence intervals (CI) between the group III and the group I was 5.143 (95% CI 1.299-20.360, p = 0.002) and between the group II and the group I 5.867 (95% CI 1.590- 21.525, p = 0.007). There were no differences in odds ratio for multivessel disease according to FINDRISC score between the group II and the group III [1.141; (95% CI 0.348-3.734). In the group I mean SYNTAX score was 5.18, and more than 70% of patients had normal coronary angiogram. In the group II mean SYNTAX score was 17.06, and more than 70% of patients had 2-vessel disease and 3- vessel disease, and in the group III mean SYNTAX score was 18.89, and 2-vessel and 3-vessel disease had 36.36% and 31.82% patients, respectively. In multiple regression analysis, where SYNTAX score was dependent variable, and age, BMI, waist circumference, FINDRISC score were independent variables, we found that only FINDRISC score was independent predictor of SYNTAX score. Conclusion. The obtained results suggest a statistically significant correlation between the FINDRISC score and its parameters (age, BMI, waist circumference) and the severity of CAD according to the SYNTAX score and the number of diseased coronary arteries. The FINDRISC score may be useful in identifying patients at the high risk for coronary artery disease.
