Heart Failure (HF) is a common disease with a high mortality rate. Anaemia and renal failure (RF) are often present in patients with HF and associated with worse prognosis. Objective of study was to evaluate the prevalence of anaemia and RF in patients with HF. Patients admitted in Punjab institute of cardiology Lahore with diagnosis of heart failure were enrolled from February, 2008 to December, 2008. Anaemia was defined as haemoglobin levels < 13 mg/dl for men and 12 mg/dl for women. Renal function was assessed by the glomerular filtration rate (GFR), calculated by the simplified formula of the MDRD (Modification of Diet in Renal Disease) study. Of the 276 patients included in this study, 42.03% (116) had anaemia and 38.40% (106) had moderate to severe renal failure (GFR < 60 ml/min). The prevalence of anaemia and renal failure was high in this population and was associated with the severity of the HF (functional classes III and IV). Source

Exercise treadmill test is interpreted as positive or negative for ischemia in the presence or absence of ST depression respectively. This study was conducted to evaluate the diagnostic value of chest pain without ST depression during exercise treadmill test. A total of 180 patients who had abnormal exercise treadmill test result and subsequently underwent coronary angiography were studied. Patients were categorised as having ST depression and angina (group A), only ST depression (group B) and only angina (group C). Coronary angiograms of all patients were assessed and compared. Out of 180 patients [159 (88.3%) men and 21 (11.7%) women], 84 patients were in Group A, 64 in Group B and 32 in Group C. Characteristics like age, sex distribution and risk factors were similar in three groups. Significant coronary artery disease was seen in 77 (91.7%), 40 (62.5%) and in 25 (78.1%) patients in groups A, B and C respectively (p=0.02). Triple vessel disease was seen in 21 (25%), 11 (17.2%) and 5 (15.6%) patients in groups A, B and C respectively. Significant disease of left anterior descending artery was seen in 61 (72.6%), 26 (40.6%) and 23 (71.9%) in groups A, B and C respectively (p=0.001). Occurrence of both ST depression and angina during exercise treadmill test has strong association with angiographic coronary artery disease whereas occurrence of either of the two has similar association with angiographic coronary artery disease with a trend towards more disease in the latter.

Background: Punjab Institute of Cardiology (PIC) is a recognised teaching hospital for cardiac care in the Punjab province of Pakistan. PIC has established a library to fulfil the research and information needs of health care professionals. This study aims to evaluate the satisfaction of users with the services of PIC library. Methodology: A purposive sample of 15 health care professionals was selected. A semistructured interview technique based on an interview guide was used for collection of data. The data were qualitatively analysed using a thematic approach. Results: Users of PIC library were satisfied with the library collection, organisation, reference and circulation services, staff attitudes, cooling and heating. They were concerned about library space, hours, furniture and environment, and suggested more availability of electronic library services, newer collections, better Internet access and comfortable furniture. Conclusion: The study proved useful to investigate users' satisfaction with the services of PIC library. It concludes that the PIC library should maintain and strengthen the services with which users are satisfied, and improve those about which they are concerned. The study will be useful to libraries in other developing countries for improvement in their services. © 2013 Health Libraries Group. Source

To compare the severity of carotid artery disease in diabetic and non-diabetic patients undergoing coronary artery bypass grafting. From January to June 2008, 379 patients undergoing elective coronary artery bypass surgery were preoperatively evaluated for the presence of carotid stenoses by duplex scanning. Patients were divided into two groups, Group I, 156 (41.2%) diabetic patients and Group II, 223 (58.8%) non-diabetic patients. There were 314 (82.8%) males and 65 (17.2%) females with a mean age of 57.2 +/- 9.1 years. In diabetic group there were 125 (80.1%) males and 31 (19.9%) females with a mean age of 56.3 +/- 8.9 years. Left main stem stenosis was present in 59 (37.8%) diabetics and 45 (20.2%) non-diabetics (p<0.0001). Diffuse disease in left anterior descending (LAD) artery was observed in more diabetic patients 72 (46.2%) as compared to non-diabetics 83 (37.2%) (p<0.295). Single tight stenosis in LAD was observed in more non-diabetics. Significant carotid artery stenosis was observed in 50 (13.2%) patients. Carotid artery stenosis was observed in 30 (19.2%) diabetics as compared to 20 (9%) non-diabetics (p<0.004). Analysis of percentage stenosis of carotid artery disease in the study population revealed that >70% stenosis was present in 20 (5.3%) with 13 (8.3%) diabetics and 7 (3.1%) non-diabetics (p<0.025). Stenosis of 50-70% was observed in 30 (7.9%) of which 17 (10.9%) were diabetics and 13 (5.8%) were non-diabetics. Presence of diabetes mellitus is associated with diffuse coronary artery disease and significant carotid artery disease in patients undergoing coronary artery bypass grafting. Source

Coronary artery bypass without cardiopulmonary bypass (CPB) has gained popularity recently with the development of devices that allow for improved exposure and standardization in off pump coronary artery bypass surgery. Off pump coronary artery bypass surgery reduces some of the morbidities traditionally attributed to CPB. The primary goal of off pump coronary artery bypass surgery is to provide an equally comprehensive operational result as the conventional operation. The purpose of the study was to compare intra operative and postoperative arrhythmias in off pump coronary artery bypass (OPCAB) verses conventional CABG. This study was a sub-group as part of a randomised control trial and was conducted from January 2006 to March 2007 at Punjab Institute of Cardiology. One hundred patients were included in 'on pump' group-A, and 100 patients in off pump' group-B. Thirty-three patients in group-A and 22 in group-B developed arrhythmias. Twenty-six patients developed atrial fibrillation in group-A and 16 patients in group-B. Mortality due to arrhythmias was 5, three were in on pump group, and 2 were in off pump group. There is non-significant tendency towards less frequency of postoperative arrhythmias in the off pump patients as compared to on pump coronary artery bypass surgery patients. Source
