: ObjectivesIn a randomized, double-blind, crossover design, we compared the efficacy of sildenafil with placebo in patients with primary pulmonary hypertension (PPH). The primary end point was the change in exercise time on treadmill using the Naughton protocol. Secondary end points were change in cardiac index and pulmonary artery systolic pressure as assessed by Doppler echocardiography and quality of life (QOL) as assessed by a questionnaire.: BackgroundPrimary pulmonary hypertension is a disorder with limited treatment options. Uncontrolled studies had shown sildenafil to be beneficial in the treatment of PPH.: MethodsAfter initial clinical evaluation, including Doppler echocardiography and treadmill exercise test, patients were randomized to placebo or sildenafil with dosages ranging from 25 to 100 mg thrice daily on the basis of body weight. The evaluation was repeated after six weeks. Then patients were crossed over to alternate therapy. Final evaluation was performed after another six weeks of treatment.: ResultsTwenty-two patients completed the study. Exercise time increased by 44% from 475 ± 168 s at the end of placebo phase to 686 ± 224 s at the end of sildenafil phase (p < 0.0001). With sildenafil, cardiac index improved from 2.80 ± 0.9 l/m2 to 3.45 ± 1.1 l/m2 (p < 0.0001), whereas pulmonary artery systolic pressure decreased insignificantly from 105.23 ± 17.82 mm Hg to 98.50 ± 24.38 mm Hg. There was significant improvement in the dyspnea and fatigue components of the QOL questionnaire. During the placebo phase, one patient died and another had syncope. There were no serious side effects with sildenafil.: ConclusionsSildenafil significantly improves exercise tolerance, cardiac index, and QOL in patients with PPH. [Copyright &y& Elsevier]

Aim: Admission to Intensive Care Unit (ICU) is a stressful event and unforeseen crisis for the caregivers. Burden and psychosocial distress among caregivers in the ICU were unexplored. Therefore, the current study was aimed to assess the caregivers' burden and psychological distress among caregivers of traumatic brain injury (TBI) patients at emergency ICU during hospitalization., Materials and Methods: A total of 60 caregivers recruited by using purposive sampling method with descriptive research design. Consent was obtained. Interview schedule of family for depression, anxiety, stress scale (DAS-21) were administered. The data were analyzed by using SPSS. Descriptive statistics and independent burden t-test were used., Results: Results revealed that male caregivers (75%) and female caregivers (25%) took part in the study. Caregivers' mean age was found to be 35.22±11.29 years. Most of the TBI survivors admitted in ICU had severe injury (8.30±3.63). Mean scores showed that caregivers had experienced financial burden (6.28±2.36), severe depression (12.15±4.84), and a moderate level of anxiety (12.85±5.20). Independent t-test showed significant difference in caregiving burden between male and female caregivers at ICU (Male = 18.43±4.83; Female = 14.29±4.83; t = 2.16; p <0.035). Overall, caregivers experienced higher family burden and severe psychological distress at ICU., Conclusion: There is an immediate need to assess psychological distress and family burden of caregivers at ICU and provide timely psychosocial intervention., How to Cite This Article: Kanmani TR, Thimmappur RM, Birudu R, Reddy KN, Raj P.

Background: Caregivers play a vital role in intensive care unit (ICU) because critically ill patients cannot make their own decisions due to their illness. Measuring family satisfaction on quality of ICU care is essential. Hence, the current paper aimed to measure the family caregiver satisfaction in ICU care in tertiary care hospital., Methods: The study adopted descriptive research design conducted from July 2016 to January 2017 at ICU in Emergency and Trauma Care center. A total number of 60 consented caregivers were recruited. An Internationally validated Family satisfaction survey questionnaire (FS) was used. Continuous variables of the data were described by mean standard deviation and categorical variables by frequency (%). Normality of the continuous variables was checked by Shapiro-Wilk test. Kruskal-Wallis test was used to compare the average FS score between the groups., Results: Results showed that caregiver age was ranged between 25 and 66 years with mean age 40 (±19). Among the caregivers, 75% were male and 25% were female of which 75% were married and remaining were unmarried. Around half of the caregivers (48.3) were educated up to primary or secondary and 26.7% had higher secondary education level. About 46.7% involved in manual laborers and 36.7% were working in the private sector. Family members had taken primary caregiving role without prior experience (81.7%) at ICU. Almost 95% of the caregivers were highly satisfied with ICU care and only 5% were not satisfied., Conclusion: Majority of caregivers are satisfied with ICU care. However, adequate measures need to be taken to ensure the complete satisfaction among caregivers at ICU., Competing Interests: There are no conflicts of interest.

Aims and Objectives: Idiopathic Pulmonary Arterial Hypertension (IPAH) is a serious disorder of unknown etiology with limited therapeutic options. Sildenafil has been shown to decrease symptoms, improve hemodynamics and quality of life. Its impact on survival is uncertain. We studied the efficacy of sildenafil in improving survival in patients with IPAH., Methods and Results: Data on survival of patients with IPAH was collected from prospectively maintained registry at our hospital from January 1999 to December 2005. Thirty nine patients who were treated with conventional therapy including digoxin, diuretics, anticoagulants and calcium channel blockers prior to January 2001 served as historical controls (control group). One hundred and thirty nine patients received sildenafil additionally from January 2001 (sildenafil group). All patients in sildenafil group showed improvement in symptoms. Survival of patients in sildenafil group was significantly better compared to historical controls receiving only conventional therapy. It was 89%, 43% and 19% in the control group Vs 93%, 75% and 54% in the sildenafil group at the end of 1, 3 and 5 years respectively (P Value=0.0002). Sildenafil was well tolerated and none of the patients had to discontinue the treatment., Conclusion: Sildenafil when added to conventional therapy improves symptoms as well as survival significantly compared to conventional therapy alone. Further randomized controlled trials are needed to evaluate its impact on survival when used either alone or in combination with other drugs.

BACKGROUND, Drug-eluting stents have enabled considerable reduction in restenosis in patients subjected to angioplasty. However, in view of high cost of drug-eluting stents, efforts to develop medicated stents at reduced cost using alternative polymers in Indian setting are imperative. Hence a multi-center study was undertaken to evaluate the safety and efficacy of the indigenously developed paclitaxel-eluting RELEASE-T stent. METHODS, The study included 100 patients (male:86, Female:14) who were undergoing angioplasty for various indications at four centres viz. Delhi, Hyderabad, Pune and Warangal. The age range was 29 - 76 years; 37 patients were diabetic. All patients were pre-treated with aspirin 150-325 mg plus clopidogrel 75 mg daily four days before procedure or clopidogrel alone. Aspirin was continued indefinitely. RESULTS, Direct stenting ws done in majority of patients. One patient, in whom stent could not be delivered, received only baloon angioplasty. Sixty-four patients had stenting of left anterior descending artery. The stent diameter ranged from 2.5 to 3.5 mm, and the length, 15 to 20 mm. All patients were followed up at 1,3 and 6 months. There was two deaths: one had subacute thrombosis on both stents, and the other (who was HIV positive) had sudden cardiac death. The 6-month rate of major adverse cardiac events was 4% and target lesion revascularization rate ws 2%. CONCLUSION, This ulti-locational study brings out that the use of indigenously developed paclitaxel-eluting stent is safe and clinically efficacious.

Background: Studies in several populations have indicated that genetic variation at the apolipoprotein E structural locus influences atherosclerosis leading to cardiovascular diseases. The possible role of apolipoprotein E polymorphism in the development of essential hypertension has not been sufficiently investigated. In this case-control study, we aimed to determine the significance of association between essential hypertension and apolipoprotein E genotypes. In addition, apolipoprotein E genotypes were correlated with serum lipid levels in order to understand the possible interaction between the specific genotype and the lipid profiles that can contribute to hypertension., Methods and Results: The apolipoprotein E genotypes were assayed in 185 patients and 200 controls by polymerase chain reaction followed by enzymatic digestion with Hha I. Using logistic regression analysis, the multivariate-adjusted odds of hypertension were calculated. The incidence of epsilon4 allele was found to be significantly higher in patients (12.16%) than in controls (5.75%, chi2=10.87; p<0.05) and also in patients with positive family history (16.7%) as compared to negative family history (8.87%, chi2 = 8.45; p<0.1). Further, it was observed that carriers of epsilon4 allele have twice as much risk (p<0.05) for developing hypertension as compared to carriers of other alleles. Patients with epsilon4 allele had significantly higher levels of total cholesterol and low-density lipoprotein- cholesterol as compared to epsilon4 allele non-carriers (p<0.05). The adjusted odds ratios for epsilon4 and epsilon2 alleles versus epsilon3 allele were 2.2 (95% confidence interval 1.2 to 3.8, p<0.05) and 1.2 (95% CI, 0.75 to 1.77, p<0.514), respectively., Conclusions: Our study revealed a strong association of apolipoprotein E locus with hypertension and lipid profile. However, large population-based studies are needed to understand the exact role played by the locus in causing the condition.

Non-surgical transpericardial approach for catheter-based epicardial radiofrequency ablation of post-infarction left ventricular tachycardia has been described as an alternative and additive procedure to standard endocardial technique for delivery of radiofrequency energy in difficult situations. We report our initial experience with this approach in three patients of post-infarction recurrent ventricular tachycardia, refactory to multiple antiarrhythmic drugs. Ablation was successful in terminating the tachycardia in two and in modifying the circuit to be amenable for control with single antiarrhythmic drug in one patient. There were no serious acute or long-term complications related to the procedure. Epicardial approach is an effective and safe adjunct to standard endocardial ablative technique for patients of post-infarction ventricular tachycardia.

Background: The prevalence of risk factors for atherosclerosis is increasing in India due to changing socioeconomic factors and lifestyles. Data for the state of Andhra Pradesh are scanty in this regard., Methods and Results: The prevalence of conventional risk factors for atherosclerosis was prospectively assessed in a unique sample of 3307 workers of a political party drawn from all over the state of Andhra Pradesh. Demographic, anthropometric, clinical and laboratory data were collected prospectively over a period of 6 months. The mean age of the subjects was 43.12+/-9.5 years, 2955 (88%) were males and 385 (12%) females. The prevalence of risk factors was as follows: diabetes in 810 (24%); hypertension in 924 (28%); lipid abnormality in 1908 (58%); smoking in 805 (24%) and positive family history in 555 (17%). Obesity was prevalent in 1178 (36%) of the population. All coronary risk factors, excepting family history, were significantly more prevalent in males [diabetes: 777 (26%) v. 34 (9%), p<0.001; hypertension: 833 (28%) v. 72 (19%), p<0.001; lipid abnormality: 1729 (59%) v. 172 (45%), p<0.001; smoking: 801 (27%) v. 7 (2%), p<0.001; and family history: 497 (17%) v. 60 (16%), p=0.54]. Region-wise analysis showed a high prevalence of diabetes in the Andhra and Rayalaseema regions, hypertension in the Andhra region, and smoking in the Rayalaseema region. Lipid disorders were equally prevalent in all the regions., Conclusions: The present report shows a disturbing burden of coronary risk factors in the study population. There is an urgent need to undertake population-based measures to reverse the trend.
