RESUMO
The treatment of choice between coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI) has remained unclear. Considering quality of life (QOL) increases life expectancy, we believe QOL should be important in determining the optimum treatment. Thus the objective of this review was to illustrate the comparative effects of CABG and PCI on postprocedural QOL. Methods. We searched PubMed (Medline) and Embase from inception of the databases to May 2014 using "PCI versus CABG quality of life", "Percutaneous Coronary intervention versus Coronary artery bypass graft surgery Quality of life", "PCI versus CABG health status", "Angioplasty versus CABG", "Percutaneous coronary intervention versus coronary artery bypass surgery health status", and different combinations of the above terms. 447 articles were found. After applying strict exclusion criteria, we included 13 studies in this review. Results. From the 9 studies that compared QOL scores at 6 months after procedure, 5 studies reported CABG to be superior. From the 10 studies that compared QOL among patients at 1 year after procedure, 9 reported CABG to be superior. Conclusion. It can be established that CABG is superior to PCI in improving patient's QOL with respect to all scales used to determine quality of life.
RESUMO
It remains a controversial issue whether internal thoracic artery (ITA) should be dissected in skeletonized or pedicled manner during coronary artery bypass graft (CABG) surgery. The main objective of this cohort study was to compare skeletonized versus pedicled grafts on the basis of patients' perceptions of their physical and mental well-being. Isolated nonemergent CABG patients were divided into two groups according to the type of graft used; skeletonized or pedicled. The quality of life (QOL) was measured preoperatively, 6 months postoperatively, and 12 months postoperatively for each patient using the 36-Item Short Form Health Survey tool. The main outcome variables were physical component summary (PCS) score and mental component summary (MCS) score. A total of 140 patients were included in the study with 70 patients in each group. The PCS (p-value = 0.235) and MCS (p-value = 0.239) scores of patients were similar in both the groups before CABG. The PCS and MCS scores were significantly (p-values < 0.0001) improved after CABG at 6 months in both the groups. However, the PCS and MCS scores in the skeletonized group were significantly higher (p-values < 0.0001) than the scores in the pedicled group at 6 and 12 months post-CABG. Both the harvesting techniques improve QOL significantly after CABG. However, skeletonization results in significantly better PCS and MCS scores compared with pedicled harvesting technique.
RESUMO
OBJECTIVE: Although mitral valve replacement is frequently performed in patients of all age groups, there are few studies available which determine the causes of operative mortality in mitral valve replacement especially in our region. Therefore, the objective of this study was to identify factors that are significantly associated with operative mortality in mitral valve replacement. METHODS: From August 2012 to March 2013, 80 consecutive patients undergoing mitral valve replacement in a single tertiary hospital were included. Patients with a history of previous coronary artery bypass graft surgery or congenital heart problems were excluded from the sample. The included patients were observed for a period of 30 days. Pre and post-operative variables were used to identify significant predictors of mortality. RESULTS: The overall hospital mortality (30 days) was 15%. High post-perative creatinine (P =0.05), high ASO titre (P=0.03), young age (P=0.011), low cardiac output (P=0.0001), small mitral valve size (P=0.002) and new onset of atrial fibrillation (P=0.007) were the significant independent predictors of operative morality. CONCLUSION: Mitral valve replacement can be performed in third world countries with limited resources with low mortality. However, optimal selection of mitral valve size can help to improve operative mortality.

STUDY DESIGN: Cross sectional study. PURPOSE: The purpose of this study was to determine the incidence and the associated risk factors of pinhole type of durotomy and cerebrospinal fluid (CSF) leakage following a simple laminectomy for spinal stenosis. OVERVIEW OF LITERATURE: The incidence of spinal stenosis is expected to rise with increasing life expectancy. Moreover, lumbar spinal stenosis is the most common indication for spinal injury in the geriatric population. It is therefore important to identify and prevent the risks associated with laminectomy, the most widely used surgical procedure for spinal stenosis. The serious complication of incidental dural tear or durotomy and subsequent CSF leakage has not been studied in the region of Southeast Asia. METHODS: In this cross sectional study, we included 138 adult patients (age>18 years), who underwent a simple laminectomy for lumbar stenosis between 2011 and 2012. CSF leakage was the main outcome variable. Patients' wounds were examined for CSF leakage up to 1 week postoperatively. RESULTS: The incidence of pinhole type durotomy and subsequent CSF leakage in our region was 8.7%. Univariate analysis showed that hypertension, diabetes and smoking were significantly associated with durotomy and increased CSF leakage by 16.72, 44.25, and 33.71 times, respectively. Multivariate analysis showed that only smoking and diabetes significantly increased the chances of leakage. CONCLUSIONS: Glycemic control and cessation of smoking prior to a simple laminectomy procedure reduced the incidence of a dural tear. Larger clinical studies on this lethal complication are required.
RESUMO
OBJECTIVE: Environmental stresses, especially extreme cold and hot weathers, have tendency to have more admissions for acute coronary syndromes. Due to scarcity of local data, we studied the variation in patient admission rates with acute coronary syndrome according to different seasons. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Coronary Care Unit, Civil Hospital and Pakistan Steel Hospital, Karachi, from January 2011 to December 2011. METHODOLOGY: The study group comprised consecutive patients with acute coronary syndrome (unstable angina, Non ST-Elevation Myocardial Infarction (NSTEMI), ST-Elevation Myocardial Infarction (STEMI) admitted to the coronary care unit. Patients with stable angina and valvular heart disease were excluded. Data was analyzed for admission according to different seasons, (winter, spring, summer and autumn). RESULTS: The mean age of the 428 cases was 48.5 ± 10.4 years (range 27 to 73 years). Among the study group, 261 (61%) and 167 (39%) cases were male and female respectively. ST-elevation myocardial infarction, non ST-elevation myocardial infarction and unstable angina were present in 206 (48%), 128 (30%) and 94 (22%) respectively. Among the 428 patients, 184 (43%) cases had hypertension, 133 (31%) cases were smokers, 103 (24%) cases had dyslipidemia and diabetes mellitus and 08 (2%) cases had history of premature coronary artery disease. The number of patients admissions with acute coronary syndrome tended to change with sudden change in season. It increased in Winter 158 (36.9%) and Summer 130 (30.3%) in comparison to Spring 80 (18.69%) and Autumn 60 (14.02%) season. CONCLUSION: It was found variation in admission rates of acute coronary syndrome patients according to different seasons. The number of admissions not only increased in the cold season (winter) but also in hot season (summer) with sudden changes in temperature.

PURPOSE: Previous studies in the western world have reported the possible association of obstructive sleep apnea (OSA) with anxiety and cardiovascular diseases. However, the data from developing countries such as Pakistan remains scarce in this regard. The main aim of this study was to investigate the prevalence of coronary artery disease (CAD) patients who are at high risk of OSA and to determine the association between the risk of OSA and levels of anxiety. METHODS: The sample population consisted of 400 participants including 200 patients, who had been previously diagnosed with CAD, and 200 healthy controls. The 200 CAD patients were approached for inclusion in the study on their follow-ups after their acute symptoms had subsided. The patients were interviewed after a mean time period of 13 weeks post event. All patients with lung disease or respiratory infection were excluded from the study. The risk of OSA was determined using Berlin questionnaire, while the levels of anxiety were measured by Beck anxiety inventory scale (BAI). RESULTS: More than half (n = 104) of the CAD patients were at high risk of OSA while majority (n = 168) of the healthy controls were at low risk. The high risk of OSA was significantly (P < 0.0001) more prevalent in CAD patients compared with controls. It was also observed that the patients who were at high risk of OSA, among both cases and controls, had significantly (P values <0.001) higher levels of anxiety. CONCLUSION: A significant proportion of CAD patients are at high risk of OSA in our region. Moreover, OSA is also associated with greater levels of anxiety in both healthy people and CAD patients.

A 62 years old patient developed myasthenia gravis 2 years after his percutaneous coronary intervention. He was advised thymectomy for myasthenia gravis. During his cardiological evaluation, he was incidentally diagnosed to have 3 vessel disease. Hence, a simultaneous surgical intervention was performed consisting of thymectomy and CABG via standard cardiopulmonary bypass through median sternotomy. Previous medical history of diabetes and corticosteroid therapy made the patient immunocompromised. Therefore, a careful overall therapeutic strategy was devised to prevent mediastinitis. After his thymectomy and coronary artery bypass grafting, he was extubated within 6 hours. Plasmapheresis was done one day before the surgery and on first postoperative day. His medications for myasthenia gravis (pyridostigmine and prednisolone) were not stopped before and after the surgery. Patient was discharged on 6th postoperative day without any complications. On his follow-up 6 weeks postoperatively, his condition was unremarkable.

A 35 years old man presented with Cauda Equina syndrome caused by a bullet migrating down the spinal canal. The patient initially showed no neurological deficits after the gunshot injury but after 15 months he presented again with urinary and fecal incontinence. Lumbo-sacral X-ray showed a bullet at the level of L5-S1 so he was operated under fluoroscopic guidance. Patient's neurological deficits improved after the operation. In authors' opinion it is vital to do follow-up after a gunshot injury to detect migrating bullet. Decompression of Cauda Equina should be done as soon as the neurological deficits occur.

Coronary artery bypass graft surgery relieves angina symptoms and reduces mortality among ischaemic heart disease patients. It remains the gold standard for the treatment of multi-vessel and left main coronary artery disease. It is a well-known fact that internal mammary artery conduits have excellent and long-lasting patency when used for coronary artery bypass grafting. Its supremacy is largely because it prevents atherosclerosis. The old-style internal mammary artery bypass grafting, classically known as pedicle grafting, includes a circular rim of tissue around the graft. Bilateral pedicled internal mammary arteries, especially among diabetic patients, have been reported to cause complications in the sternum like sternal osteomyelitis. In many studies it has been reported that dissection of pedicled internal mammary artery can lead to sternal devascularisation which can lead to higher incidence of infections. Considering the higher incidence of deep sternal infections in patients with double pedicled arterial grafts, dissection of internal mammary artery in skeletonised manner was proposed. In this review, we outline the advantages of skeletonised grafting with respect to incidence of sternal infection, patency rates, blood flow, post-coronary artery bypass graft pain and the length of the graft.

PURPOSE: We hypothesized that gender, age, aortic root dimension, blood group and Left Ventricular End Diastolic and Systolic Diameters may have a significant correlation with the size of mechanical valve used. METHODS: We included 48 patients retrospectively who had been operated at a single tertiary hospital. All patients with aortic stenosis or regurgitation were included in the study. Patients who had undergone previous cardiac surgery or concomitant surgical procedures, such as coronary artery bypass grafting, were excluded from the study. RESULTS: The median size of the valves used in males (23mm) and females (21mm) were significantly different (P = 0.001). Size of the valve used was significantly associated with Left Ventricular End Systolic Diameter (LVESD) (r = 0.327, P = 0.007) and aortic root dimension (r = 0.526, P < 0.001). Moreover, significantly higher values of LVESD were observed in the expired patients (P = 0.023). CONCLUSION: This study shows that aortic root dimension and gender may be important predictors for the size of the prosthetic aortic valve used in aortic valve replacement. Our study also concludes that LVESD has significant relationship with in-hospital mortality. However, more long term clinical trials should be conducted to confirm these relationships.

There are two basic ways of performing coronary artery bypass graft surgery (CABG): on pump CABG and off pump CABG. Off pump CABG is relatively a newer procedure to on-pump CABG and does not require the use of the cardiopulmonary bypass machine. On pump CABG is the more traditional method of performing bypass surgery. However its resultant inflammatory effects cause renal dysfunction, gastrointestinal distress and cardiac abnormalities which have forced the surgeons to look for alternatives to the procedure. An extensive literature search revealed that on pump CABG causes better revascularization as compared to off pump CABG while off pump CABG has a much lower post operative morbidity and mortality especially in high risk patients. We suggest that the technique used should depend on the ease of the surgeon doing the operation as both the methods seem almost equally efficient according to the review.

BACKGROUND: The primary objective of the study was to find out the frequency of tobacco smoking among health care providers in tertiary care hospitals of Karachi. The secondary objective was to identify the common factors responsible for the continuation of smoking. METHOD: This cross sectional study was conducted in the wards and out-patient departments of three selected tertiary hospitals of Karachi. A total of 180 health care providers were enrolled in the study using proportionate stratified sampling. Postgraduate students, house officers and trainees were excluded from the study. Data were collected from randomly selected health care providers using survey methodology. SPSS v. 20.0 was used to enter and analyze the data. RESULTS: Fifty two participants out of 180 were smokers for past one year (28.9%). Among them, 21 (11.7%) smoked more than 5 cigarettes per day. Twenty smokers (11.1%) were found to smoke due to peer influence. It was found that those who were influenced by their peers were 8.33 times more prone to be addicted to smoking than those who were less influenced. Similarly, the likelihood of addiction increased up to 76.9% with the lack of incentives. CONCLUSION: Our results clearly indicate that a large number of health care providers smoke which should be a serious concern. Hence our health agencies should take immediate action in order to curtail the heaving burden of smoking and its related health consequences.

A barber shop is a potential place for non-sexual transmission of deadly blood borne diseases such as acquired immuno-deficient syndrome. Few researches have been conducted to assess the knowledge of barbers regarding human immunodeficiency virus (HIV) transmission in Pakistan. With majority of the population visiting roadside saloons, it is imperative to have local data in this regard. The objective of this study was to investigate the knowledge and practices of barbers with reference to razor use and steps taken to sterilize their instruments. A total of 300 barber saloons were conveniently selected for this cross-sectional study during a time period of 5 months from May 2012 till September 2012. The shops were categorized into three groups: big saloons, small saloons and roadside saloons based on the inclusion criteria. One barber was randomly selected as a representative from each saloon. Data collection from each barber shop was carried out by an interviewer using a pre-coded questionnaire. Majority of the barbers had low school education. Awareness regarding sharing of blades as a route of HIV transmission was known by 90 % (n = 90) of big saloon barbers with awareness decreasing in small (n = 55) and roadside saloon barbers (n = 27). Only 60.3 % (n = 181) of the barbers used new blades between customers. In comparison to big saloon barbers, the majority (n = 53) of roadside saloon barbers used tap water for cleaning purposes. Only 40 % of the roadside barbers used antiseptic after shaving. The results of our study indicate that roadside saloon barbers, to whom majority of Pakistani population visit, have inadequate awareness regarding HIV transmission. Their poor barbering practices were mainly due to their low education. This potentiates a great risk for aggravating the HIV endemic in Pakistan.

Compliance to dietary recommendations among hypertensive people is a major health care issue. Non-compliance can nullify the effects of even the most scientific and optimum treatment plan. The main aim of this study was to determine the frequency and predictors of non-adherence in our region. We also investigated the possible factors based on patient opinions that could increase compliance. A sample of 400 adult patients, diagnosed with hypertension for at least 3 years, who visited Civil Hospital during the time period April-June 2013 were included in this cross sectional study. Patient data and opinions were collected by two trained interviewers using a pre-coded questionnaire. Compliance was assessed based on patients self report. More than three quarters (n = 310, 77.5%) of the hypertensive patients were non-compliant. More than one social gathering in a week, peer-influence, no friends to follow the recommended diet plan and lack of believe regarding diet as an effective measure to control blood pressure were found to be the significant predictors of non-compliance (P values <0.0001). Counseling was thought to be the most effective way by the patients to increase adherence. Non-compliance to dietary recommendations is a major problem prevalent especially in Pakistan. There is an urgent need for doctors and nurses to counsel their patients effectively to prevent future morbidities and mortalities because of non-compliance.

BACKGROUND AND AIM: Benefits of the skeletonized internal thoracic artery (ITA) include increased graft flow, increased graft length, and reduced incidence of sternal complications. We conducted a randomized, double-blinded comparison of skeletonized versus pedicled ITA to assess the differences in pain intensity and extent of disability between the two types of harvesting procedures at one and three months follow-up. METHODS: A total of 50 patients were included in our study. Twenty-five patients had undergone skeletonized grafting while the other half had undergone pedicled grafting. The patients were evaluated for their pain at one and three months postoperatively. Extent of disability was measured via Pain Disability Index and intensity of pain was measured via Visual Analogue Scale (VAS). The patients were also questioned about the details of their pain using Short Form McGill Pain Questionnaire. RESULTS: In the first month, the mean pain intensity measured through VAS was 30.4 ± 4.0 and 55.0 ± 5.7 mm in skeletonized and pedicle group, respectively. The pedicled group had significantly higher scores measured by all three scales at both one- and three-month intervals (p-values < 0.0001). CONCLUSIONS: Our results indicate that skeletonization of ITA significantly reduces postcoronary artery bypass graft surgery pain at both one- and three-month intervals. Long-term clinical trials involving larger sample sizes should be conducted to fully confirm the benefits of the skeletonization technique.
