RESUMEN
The present study assessed incidence, risk factors, in-hospital and short-term outcomes associated with no-reflow in patients undergoing percutaneous coronary intervention (PCI) in STEMI, NSTEMI, unstable angina and stable angina. Out of 449 patients, 42 (9.3%) developed no-reflow. Hypertension, dyslipidemia, obesity and smoking were significant risk factors. There was significant association of no-reflow with left main disease, multiple stents, target lesion length≥ 20 mm and higher thrombus grade. Interestingly, 93 patients (23.4%) of normal flow had myocardial perfusion grade (MPG) of 0/1 with mortality in 9 (10%) patients. No-reflow is associated with poor in-hospital and short-term outcomes with higher incidence of death, cardiogenic shock, heart failure and MACE. Knowledge of risk factors of no-reflow portends a more meticulous approach to improve final outcomes. MPG could be better predictor of outcomes in these patients.

We present a 48-year-old male patient with extensive lower-limb swelling and chronic kidney disease. Angiography revealed evidence of thrombus in the iliacs and the inferior vena cava was not visualized. Angioplasty of the entire length of the inferior vena cava is a challenging procedure. Surgery is rarely an option. Extensive skill and patience are needed and stenting is usually advised. In many cases, plain angioplasty may be done with favorable results.

BACKGROUND: Despite the high prevalence of rheumatic heart disease (RHD) in developing countries such as India, data on characteristics, complications, and treatment practices are lacking. The HP-RHD (Himachal Pradesh Rheumatic Heart Disease) registry aimed at reporting these parameters in patients with RHD from a northern state of India. METHODS: A total of 2,005 consecutive patients of RHD were enrolled over a period of 6 years (2011 to 2016) in the present study. The clinical characteristics, complications, and treatment practices were systematically recorded. RESULTS: The mean age for patients with RHD was 40.3 ± 14.3 (range 5 to 83 years). RHD predominantly affected females (72.3%) and population from rural background (92%). Multivalvular involvement was frequent (43.2%), mitral valve was the commonest affected valve (83.3%). The majority of the patients had moderate-to-severe valvular dysfunction (69.3%). Mitral and tricuspid valve involvement was more frequent in female subjects compared with more frequent aortic valve involvement in male subjects (p < 0.001). The major adverse cardiovascular events were recorded in 23.4% patients at the time of registry and comprised mainly advanced heart failure (15.6%), peripheral embolism (4.1%), and stroke (3.9%). The independent risk determinants of major adverse cardiovascular events (were advanced age (odds ratio [OR]: 1.01; 95% confidence interval [CI]: 1.00-1.02), severe mitral stenosis (OR: 1.73; 95% CI: 1.34-2.20), severe tricuspid regurgitation (OR: 2.11; 95% CI: 1.48-3.02), presence of pulmonary artery hypertension (OR: 1.33; 95% CI: 1.04-1.69), and atrial fibrillation (OR: 1.64; 95% CI: 1.28-2.11). Evidence-based use of oral anticoagulant therapy was documented in 77.7% of high-risk patients. Only 28.5% of study population was receiving secondary prophylaxis. CONCLUSIONS: Complications in patients with RHD increase with age and worsening valvular dysfunction. Programs focused on early detection and evidence-based management will assist in improving outcomes.

OBJECTIVES: Reviewed the etiologies, pathophysiologic mechanisms, detection and clinical significance of pulsus paradoxus in various conditions. DATA SOURCE: We searched PubMed, EMBASE, and the CINAHL from inception to June 2017. We used the following search terms: Pulsus paradoxus, pericardial effusion, acute asthma, ventricular interdependence and so forth. All types of study were chosen. RESULTS AND CONCLUSION: Legendary physician Sir William Osler truly said that "Medicine is learned by the bedside and not in the classroom." Bedside history taking and physical examination should be an integral component of clinical teaching curriculum imparted to medical students. Pulsus paradoxus is a valuable physical sign seen in many clinical conditions. Pulsus paradoxus is defined by an inspiratory fall in systolic blood pressure of greater than 10 mm Hg. Two prototype examples of pulsus paradoxus are cardiac tamponade and acute asthma. Exaggerated swings of intrapleural pressure, bi-ventricular interactions and increase afterload of the left ventricle are few of the pathophysiological mechanisms involved in the causation of pulsus paradoxus. The sensitivity of pulsus paradoxus in the diagnosis of cardiac tamponade is very high. In acute asthma, it also correlates with the severity of airflow obstruction.

PURPOSE OF STUDY: :Pulmonary embolism is a common emergency in the hospital setting. Main line of treatment is anticoagulant therapy. However, patients with right ventricular dysfunction are the subgroup with increased mortality and may have better outcome with initial treatment with thrombolytic therapy. The study was done to see the outcome of thrombolytic therapy in angiographically proved patients of pulmonary embolism. METHODS: We performed systemic workup of patients suspected of pulmonary embolism(PE). Diagnosis of PE was ruled out in patients with low probability of PE, as defined by Wells score and negative d dimer asssay. All patients were subjected to echocardiography. Those showing findings suggestive of PE, with right ventricular dysfunction, with or without hypotension, were subjected to pulmonary arteriography. Patients having evidence of PE were subjected to thrombolysis. Repeat angiography was done after the thrombolysis to see the effect of thrombolysis and fall in pulmonary artery pressures. RESULTS: :27 consecutive patients with angiographically proved PE were thrombolized. Mean age was 45.8±15.2 years. 18 were male and 9 were female. Average systolic and mean pulmonary artery pressure before thrombolysis was 71.2±14.4 and 47.5±10.5 mm Hg. Angiographic success was seen in 22 patients (81.5%). Average systolic and mean pulmonary pressure after thrombolysis was 47.1 ±21.7 and 29.4±16.5 mm Hg. Three patients with unsuccessful thrombolysis were successfully subjected to trans catheter thrombus extraction. One patient died during thrombolysis. None of the patients had major bleeding complications. CONCLUSION: Thrombolysis is effective in majority of patients with pulmonary embolism with right ventricular dysfunction. The bleeding risk is low.

BACKGROUND: The study aimed to estimate the prevalence, risk determinants, and its clinical significance of iron deficiency and anemia in patients of nonischemic heart failure with reduced ejection fraction (HFrEF). METHODS: Serum ferritin, transferrin saturation, and the hemoglobin (Hb) levels were measured in 226 consecutive patients with HFrEF diagnosed based on the left ventricular ejection fraction ≤ 45% and absence of coronary artery luminal narrowing of more than 50%, in a prospective tertiary care hospital-based heart failure registry. Patients with the New York Heart Association functional class III/IV were classified as patients with advanced heart failure. Multivariable logistic regression modeling was performed to assess the risk determinants of iron deficiency and anemia and their clinical significance as the risk factors for advanced heart failure. Odds ratio with 95% confidence interval (CI) was reported as the estimates of the strength of association between exposure and outcome variables. RESULTS: Iron deficiency and anemia were prevalent in 58.8% (52.2%-65.1%) and 35.8% (29.8%-42.3%) of patients, respectively. Female gender [OR 3.5 (95% CI 1.9-6.5)], history of bleeding [OR 11.7 (95% CI 1.4-101.2)], and vegetarian diet [OR 2.5 (95% CI 1.4-4.6)] were significantly associated with iron deficiency, while diabetes [OR 3.0 (95% CI 1.40-6.5)], estimated glomerular filtration rate [OR 0.98 (95% CI 0.97-0.99)], history of bleeding [OR 13.0 (95% CI 2.3-70.9)], and female gender [OR 2.9 (95% CI 1.5-5.7)] had significant association with anemia. The Hb level (OR 0.82 (95% CI 0.70-0.96) and transferrin saturation (OR 0.98 (95% CI 0.96-0.99)] had a significant inverse association with symptoms of advanced heart failure. CONCLUSION: Iron deficiency and anemia are common comorbidities associated with HFrEF. Low Hb and transferrin saturation are significantly associated with advanced heart failure. The findings have important implications in the management of heart failure.

OBJECTIVE: To report the prevalence, risk factors and consequences of atrial fibrillation (AF) in patients of rheumatic heart disease (RHD). METHODS: The Himachal Pradesh- Rheumatic Fever/Rheumatic Heart Disease (HP-RF/RHD) Registry database of 1918 patients was analyzed. AF was diagnosed with 12-lead ECG recording at entry in to the registry. The association of AF with nature and severity of valvular dysfunction was analyzed, adjusted for age, left atrial (LA) dimension and pulmonary arterial hypertension using multivariable logistic regression model and strength of association was reported as odds ratio (OR) with 95% confidence intervals (C. I.). RESULTS: The study population consisted of young (40.2⯱â¯14.3â¯years), predominantly females (72.3%) from rural area (94.1%). Prevalence of AF was 23.9% (95%â¯C. I. 22.1%-25.8%). The independent determinants AF were age (OR 1.04, 95% C.I. 1.03-1.06), LA size (OR 1.10, 95% C.I. 1.08-1.11). The association of AF with age, New York Heart Association functional class, mitral stenosis severity and tricuspid regurgitation was statistically significant and graded. Mitral regurgitation and aortic valve disease had no significant independent association with AF. The prevalence of heart failure, stroke, peripheral embolism and mortality was significantly higher among patients with AF (pâ¯<â¯.01). CONCLUSION: AF is common in RHD patients and is significantly associated with heart failure and systemic thromboembolism. Age, mitral stenosis severity, tricuspid regurgitation and LA size were independently associated with AF.
