BackgroundPeripheral artery disease (PAD) may be a useful tool to predict coronary artery disease (CAD) in patients undergoing coronary angiography. If proven that PAD can be a good predictor of CAD, it can help in early and cost-effective diagnosis of CAD. MethodologyThis observational study was conducted from January 2020 to February 2021 in the cardiology unit of a tertiary care hospital. Participants older than 40 years, with a history of uncontrolled hypertension and unstable angina, who warranted the need of angiography were enrolled in study. After enrollment and recording history, these cases were assessed for the presence of PAD based on ankle brachial index (ABI). ABI values less than 0.9 were labelled as participants with PAD. Then these cases underwent coronary angiography at the same institute, and the presence of greater than 50% stenosis of any coronary vessel on angiography was taken as positive CAD. ResultsIn this study, PAD was identified in 152 (62.8%) participants. A total of 165 (68.1%) participants had greater than 50% stenosis on angiography. Out of 152 participants with ABI less than 0.9, 140 had greater than 50% stenosis on angiography. In total, 90 participants had ABI more than 0.9, of which 35 participants had greater than 50% stenosis. Sensitivity of PAD in predicting coronary artery stenosis was 80.0% (95% confidence interval [CI]: 73.30%-85.66%), specificity was 82.09% (95% CI: 70.80%-90.39%), and accuracy was 80.58% (95% CI: 75.02%-85.37%). ConclusionsOur study demonstrated that the sensitivity, specificity, and accuracy of PAD in predicting coronary artery stenosis were significant. Hence, we conclude that PAD can be an excellent predictor of CAD by helping in early and cost-effective diagnosis of CAD.

AIM:This study aimed to assess if clinical remarks gained by analysis of the present and past medical history of patients undergoing elective coronary angiography (ECA) due to typical chest pain can help to predict the outcome of ECA.MATERIAL AND METHODS:One hundred and fifty-four ECA candidates with a history of typical chest were seen on the same day intended for ECA in the cardiac centre of AlShaab Teaching Hospital, Khartoum, Sudan. The details of the present complaints, characteristics of chest pain, past medical and socioeconomic history were recorded from each subject guided by a questionnaire. ECA confirmed CAD in 112 of the studied patients and were considered as the test group. The remaining patients (N = 42) were diagnosed as CSX after exclusion of significant narrowing of the coronary vessels and were considered as the control group.RESULTS:Univariate analysis of pain characteristics among patients undergoing coronary angiography revealed that pain is less likely to radiate to the neck (OR = 0.44, 95% CI = 0.21 – 0.91, P = 0.027) and the back (OR = 0.48, 95% CI = 0.23 – 1.00, P = 0.049) in patients with CAD. Presence of shortness of breathing and/or dizziness significantly decrease the odds of having abnormal coronary angiography (OR = 0.30 and 0.48, 95% CI = 0.12 – 0.77 and 0.22 – 0.92, P = 0.013 and 0.030 respectively). Past history of diabetes mellitus significantly increases the odds of having abnormal coronary angiography (OR = 3.96, 95% CI = 1.68 – 9.30, P = 0.002). In contrast, past medical history of migraine decreases the odds of having positive finding in ECA (OR = 0.31, 95% CI = 0.13 – 0.72, P = 0.006).CONCLUSION:Characteristics of chest pain are comparable in CAD and CSX. However, pain is less likely to radiate to the neck and/or the back in the first group. Presence of dyspnea and dizziness during angina attacks as well as the history of migraine significantly decreases the odds of having abnormal coronary angiography.

Background: Diabetes mellitus is one of the significant risk factors for adverse outcomes after coronary artery bypass surgery. The glycosylated haemoglobin i.e. HbA1c is a reliable diagnostic test to know the long-term glycemic status. The objective of the study is to investigate the implication of preoperative HbA1c level on short term outcomes after coronary artery bypass grafting (CABG).Method: Total 218 patients were studied, and the data were collected retrospectively. Patients are distributed into group 1 with HbA1c≤7 (good glycemic control) and group 2 with HbA1c>7 (poor glycemic control). The parameters studied for short term outcomes were revision due to bleeding, duration of mechanical ventilation, cerebrovascular accident (CVA), atrial fibrillation (AF), renal failure requiring dialysis, infective complications like sternal and leg wound infection, mediastinitis, pneumonia, urinary tract infection (UTI), sepsis; length of ICU stay and in-hospital mortality.Result: In comparison to group 1, patients of group 2 showed statistically significant more morbidity in view of short-term outcomes in this study.Conclusion: HbA1c>7 is associated with statistically significant adverse short-term outcomes after CABG.

Introduction: Chronic rheumatic heart disease is much the commonest cause of mitral stenosis. Incidence of rheumatic MS parallels that of acute rheumatic fever. Atrial fibrillation usually develops in the presence of pre-existing ECG evidence of left atrial enlargement and is related to the size of the chamber, the extend of fibrosis of the left atrial myocardium, the duration of the atriomegaly and the age of the patient. Study Design: Descriptive Setting: Mayo Hospital, Lahore and Punjab Institute of Cardiology, Lahore Type of sampling: Convenient No. of cases: 129 consecutive cases of predominant mitral stenosis. 112 cases included in the final workup. Results: The frequency of AF in MS in this study was calculated as 25.9%. The correlation between AF and left atrial size was significant (p = 0.000). This was plotted on the scattergram (Figure No. 1), which shows a steep rise in the frequency of AF beyond a left atrial size of 70 mm. Conclusions: Frequency of AF in patients with MS is 25.9%. The correlation between AF in MS and left atrial size is significant (p = 0.000).
