BackgroundThe objective of the study was to determine the long-term outcomes, including mitral restenosis and regurgitation, after successful percutaneous transvenous mitral commissurotomy (PTMC).MethodsThis cross-sectional prospective study was conducted at the cardiology department of Lady Reading Hospital, Peshawar, Pakistan, from January 2007 to December 2009. A total of 84 patients were followed up for a period of 96 months. Pre and post percutaneous transvenous mitral commissurotomy echocardiography was done on the mitral valve area (MVA) using two-dimensional (2D) and color doppler echocardiography. Patients who had successful PTMC were followed up for MVA loss, mitral regurgitation (MR), and cardiac death. SPSS Software (IBM SPSS Statistics for Windows, Version 22.0, Armonk, NY: IBM Corp.; 2013) was used for data analysis.ResultsOf the 84 patients, 21 were male, and 63 were females. The mean age was 35 ± 11 years. After PTMC, the mean valve two-dimensional area increased from 0.84 ± 0.13 to 1.83 ± 0.49 cm2 (p value <0.001). MR was mild in 49 patients (62.8%), moderate in 27 patients (34.6%), and severe in two patients (2.6%). Good results were achieved in 60 (71.4%). Patients with good results were younger (24 ± 4), and had a relatively lower Wilkin's score, with a mean value of (8.4 ± 2.8). Follow-up events were death in six patients, mitral valve replacement (MVR) in 10 patients, and restenosis in seven patients. The Kaplan-Meier curve was used for the follow-up end points. Patient who required PTMC for mitral restenosis survived for a longer time than those requiring MVR, and those who had cardiac death due to severe pulmonary hypertension or heart failure.ConclusionPatients who had favorable Wilkin’s score and underwent PTMC for severe symptomatic mitral stenosis had better event-free survival in the long term follow-up.

Objective:To determine the frequency of subclinical hypothyroidism in local adult obese population.Methods:The study was conducted at Hayatabad Medical Complex, Peshawar, from March, 2017 to August, 2017. All patients aged between 18 and 60 years with BMI of more than 29kg/m2 were included in the study. Patients on lipid lowering drugs, with renal failure, hepatic failure and already diagnosed cases of thyroid dysfunction were excluded from the study. Thyroid functions were measured for all patients.Results:A total of 127 adults were included in the study in a consecutive manner. Mean age was 34.5 + 7.9 years of which 46.5% were male and 53.5% were female. Mean BMI was 32.05±2.06 kg/m2. The mean serum TSH was 3.13±1.10 mIU/L and mean serum thyroxine level was 1.08±0.25ng/dl. Subclinical hypothyroidism was recorded in 15% of the study population.Conclusion:Subclinical hypothyroidism is highly prevalent in our population with BMI of more than 29kg/m2. Further studies are recommended on relationship between thyroid functions and BMI and its effect on cardiovascular functions.

Enhanced External Counterpulsation (EECP) is a non-invasive FDA approved therapy for patients with refractory angina pectoris. The EECP mechanism of action is similar to that of an intra-aortic balloon pump (IABP) by administering a vigorous pressure pulse via external blood pressure cuffs during the diastole. The benefit of EECP includes improvement in angina severity, angina stability, maximal walking capacity and generalized improvement in overall health. Seatle Angina Questionnaire (SAQ) is a valid, reliable and sensitive measure of healthrelated quality of life. It is also a sensitive and reproducible evaluation tool to measure the response to an intervention. We did a pre-test post-test designed prospective study to evaluate the effect of EECP on the quality of life in patients with CAD. There was a significant difference between SAQ-7 health-related quality of life between the pre-EECP and post-EECP groups (P value= <0.01). Moreover, a positive correlation was reported between the New York Heart Association (NYHA) Functional Classification before treatment and post-EECP SAQ-7 healthrelated quality of life (P value=0.015).

Objective:To determine the frequency of intraventricular dyssynchrony among patients with left bundle branch block.Methods:The study was conducted at Hayatabad Medical Complex, Peshawar, from January, 2017 to July, 2017. All patients aged 18 years and above with Left Bundle Branch Block (LBBB) on ECG with or without heart failure were included in the study. Patients with valvular heart disease, predominant diastolic heart failure, acute coronary syndromes or coronary revascularization in last three months and atrial fibrillation were excluded. Tissue Doppler Imaging (TDI) parameters were measured from 2-D images in apical 4-chamber and 2-chamber views. Consecutive non-probability sampling technique was used for sample collection.Results:Our study included 159 patients. Mean age was 52 years with SD ± 2.74. Ninety-nine (62%) patients were male and 60 (38%) patients were female. One hundred and three (65%) patients had heart failure while 56 (35%) patients didn’t have heart failure. More over in our study 124 (78%) patients had Intraventricular dyssynchrony while 35(22%) patients didn’t have Intraventricular dyssynchrony.Conclusion:The incidence of Intraventricular dyssynchrony is high among patients with heart failure and left bundle branch block.

The results of this study suggest that endoscopic GSV excision showed no difference in adverse events between treatments, although our pilot study may have been under-powered to demonstrate this. The SF-36 assessment suggests more rapid return to normal activities post-operatively in the endoscopic group.
