Objectives: To investigate the diversity and average values of bifurcation angles in a large population to help develop new methods. Methods: One thousand five individuals (504 females, 501 male) who visited the Cardiology Polyclinic of Fırat University Hospital with the complaint of chest pain between 2010 and 2015 were evaluated retrospectively. Bifurcation angle measurements between LMCA-CX, CX-LAD, LMCA-LAD, CX-OM1, CX-OM2, LAD-D1, LAD-D2, RCA-RMD, RCA-RVD and PDA-PL were evaluated in all cases. Results: Bifurcation angles between LMCA-LAD, LMCA-Cx and LAD-Cx branches with “> 90 wide angle bifurcations”, and Cx-OM1, Cx-OM2, LAD-D1, LAD-D2, RCA-RMD and PDA-PL with “<70 Y type bifurcation angle” were found to be high in male and female individuals. The RCA-RVD in female individuals was “<70 Y-type bifurcation” in 14 (2.8%) people, “> 70-90 T-type bifurcation” in 209 (41.5%) people, and “> 90 wide angle bifurcation” in 281 (55.8%) people. Results for male subjects were compatible with this. The correlations of all angles were examined. Robust positive correlations (p≤0.001) were found for the angular measurements between the main branches and the side branches (Cx-OM1, Cx-OM2, LAD-D1, LAD-D2 and RCA-RMD, PDA-PL). Conclusion: With the help of developing technology, we believe that all this coronary angiography data will guide bifurcation stent techniques, which are essential alternatives to bypass. doi: https://doi.org/10.12669/pjms.38.3.4782 How to cite this:Deniz G, Kavakli A, Kucukukur M, Kose E, Karaca I.

Introduction: Screening for coronary artery disease in patients being considered for kidney transplant is common to stratify morbidity and mortality risk, but the optimal strategy, and its impact on outcomes, remains unclear. Here we test the hypothesis that myocardial perfusion imaging (MPI) abnormalities, left ventricular ejection fraction (LVEF), or coronary artery calcium (CAC) score are associated with all-cause mortality in potential kidney transplant recipients at Emory University Hospital (EUH). Methods: In a retrospective chart review, we assessed the relationship between patient demographics, single-photon emission MPI results, and CAC scoring with post-evaluation outcomes at 5 years in consecutive patients referred for pre-transplant stress testing at EUH in 2015. Mann-Whitney U and Chi-Square tests assessed between-group differences in continuous and categorical variables, respectively. Multivariate analysis was performed using logistic regression models. Results: During the study period, 589 patients (mean age 54 years; SEM 0.512, 58% male, 65% African American) underwent MPI and 424 also underwent CAC scoring. Overall, 90 patients (15%) had abnormal MPI (defined as any fixed or reversible defect) and 54 (9%) died during follow up. Age (mean 53.2 years; SEM 0.533 vs. 57.7 years; SEM 1.73, p=0.008), previous coronary artery bypass graft (CABG) (2.06% vs. 7.41%, p=0.017), and myocardial infarction (MI) post-evaluation (4.11% vs. 18.5%, p<0.001) were associated with all-cause mortality. Age (p=0.032) and MI post-evaluation (p<0.001) remained significant in multivariate analysis. MPI abnormalities, LVEF, and CAC score were not associated with all-cause mortality. Conclusions: Age and MI post-evaluation are associated with increased mortality in potential kidney transplant recipients referred for stress testing at EUH. We found no association between MPI abnormalities, LVEF, or CAC score and all-cause mortality.

Objective: To evaluate risk factors having significant effect on mortality of smear positive Pulmonary Tuberculosis (PTB) inpatients. Methods: A descriptive cross-sectional study was conducted at Ojha Institute of Chest Diseases, Dow University Hospital Ojha Campus, Karachi. One hundred and seventy (170) inpatients of smear positive PTB confirmed by Acid Fast Bacilli (AFB) smear, aged between 13-80 years were enrolled by using consecutive sampling technique while patients with drug resistant Tuberculosis (TB) and extra pulmonary TB were excluded from the study. Selected patients were interviewed for collecting demographic data and risk factor data by using a standard questionnaire. Results: Out of 170 PTB inpatients, mortality was observed in 23 (13.5%) patients among which male patients were 12 (52.2%), and female were 11 (47.8%). Mortality was significantly associated with increasing age (p=0.003), socioeconomic status (p=0.019), anemia (p=0.03), Chronic Liver Disease (CLD) (p=0.005), Diabetes Mellitus (DM) (p=0.001), Human Immunodeficiency Virus (HIV) (p=0.007), Hypertension (HTN) (p=0.006), recurrent TB (p=0.001), and smoking (p=0.001). Conclusion: Increasing age, poverty, smoking history, and presence of comorbidities like DM, CLD, HIV, hypertension, and anemia are associated with higher mortality in smear positive PTB cases. doi: https://doi.org/10.12669/pjms.35.5.919 How to cite this:Hameed S, Zuberi FF, Hussain S, Ali SK.

Objectives: To assess the overall survival of pregnant women diagnosed with cancer during pregnancy or became pregnant thereafter. Methods: A retrospective medical record review of 90 patients who were diagnosed with cancer when pregnant or who became pregnant thereafter between 1996 and 2015 in Aga Khan University Hospital, Karachi. Results: A total of 90 patients were analyzed. The malignancies that expectant mothers had were, breast cancer 38 (42.2%), hematological cancers 29 (32.2%), brain cancer 10 (11.1%), and other malignancies 13 (14.4%) that included thyroid cancers, gestational trophoblastic disease and synovial tumor of foot. We observed only four deaths out of 90 patients and mean survival time in pregnant patients with malignancies was 17.98 years [CI 16.35-19.31]. Conclusions: The diagnosis of most cancer types before or during pregnancy does not influence on overall survival of patients. doi: https://doi.org/10.12669/pjms.37.2.3525 How to cite this:Dur-e-Shahwar, Irfan S, Islam ZS, Sheikh L.

Abstract To determine possible associations between lipoprotein(a) [Lp(a)] and the severity of coronary artery lesions, we measured lipid, apolipoprotein, and Lp(a) in a large population of Belgian patients (n = 1054) undergoing coronary angiography. In both women and men, univariate analysis demonstrated significant differences in the Lp(a) concentrations according to the severity of the coronary stenosis. However, after adjustment for possible confounding factors, many of these differences were attenuated, indicating that other variables that differentiate patients from control subjects also influence Lp(a) distribution. Differences in lipid, apolipoprotein, and Lp(a) concentrations between male and female patients are discussed.
