RESUMO

Free-floating thrombus in the right ventricle, associated with a massive acute pulmonary embolism (PE), is a rare phenomenon. PE is an important clinical entity with considerable mortality despite advances in diagnosis and treatment. The prognosis of PE depends on right ventricular dysfunction, myocardial injury markers, and early treatment. In this report, we present the case of a 71-year-old woman with a history of breast cancer admitted to intensive care unit for PE complicated by syncope. Although our case may seem complex because it is not represented in the guidelines, the result was satisfactory and showed how treatment with new anticoagulants (in this case apixaban) after massive thrombolysis of PE could be considered and included in the new guidelines.

RESUMO

This case report describes agranulocytosis immediately after oral administration of dabigatran in a 68 years old man with atrial fibrillation (AF). Dabigatran is an oral, reversible and competitive thrombin inhibitor that has shown promising results. In patients with atrial fibrillation of RE-LY study (Randomized Evaluation of Long-Term Anticoagulant Therapy), dabigatran administered at a dose of 150 mg, as compared with warfarin, was associated with lower rates of stroke and systemic embolism but similar rates of major hemorrhage. Dabigatran is administered as a prodrug and the peak of the plasma concentrations occurs within 2 h of ingestion. Agranulocytosis is characterized by a severe decrease or lack of circulating granulocytes. This rare event can be found among people taking dabigratan, especially for people who are female, over the age of 60, who took the drug for < 1 month. Agranulocytosis and aplastic anaemia are rare but serious conditions known to be caused by numerous drugs. Most of what is known or suspected about the aetiology is based on case reports, with only a few formal epidemiological studies that provide quantitative estimates of risk. The patient's white blood cell count increased abruptly after discontinuation of the drug, suggesting an immune response caused by dabigatran. Although anticoagulant drugs are commonly used to treat atrial fibrillation, attention should be paid to this aspect and possible drug interactions.

RESUMO

Congestive heart failure (CHF) worsening is a worldwide cause of rehospitalization and mortality, specially during the early period after hospitalization. Fluid accumulation plays a key role in the pathophysiology of both acute heart decompensation and disease progression. The effective use of drugs to maintain restored clinical stabilization in recently discharged patients is a difficult task, and it relies on matching the most appropriately tailored therapy to specific clinical profiles. However, no successful treatment has been shown to reduce post-discharge readmission. We evaluated in a case-control study the effectiveness of an early and personalized congestion-guided ambulatory program on medium-term (6 months) compensation in recently discharged CHF patients. Group A (22 patients) underwent a post-discharge close follow-up consisting of: an early clinic visit within 10 days; a second visit within 10 days after the first; and the other visits at month 1, 2, 3 after discharge. Controls (Group B, 21 patients) underwent a conventional ambulatory follow-up only at month 1, 2, 3 after discharge. The ambulatory approach in both groups was based on the monitoring of signs/symptoms of congestion and body weight, body hydration estimation by using bioelectrical impedance analysis (BIA) and laboratory data. This assessment was finalized to tailor furosemide and daily fluid intake at each visit to eliminate clinical or instrumental evidence of persistent congestion relieving the signs and symptoms. At 6 months, Group A was associated with a better clinical compensation (improved hydration state, lower BNP levels and congestion score), an improved quality of life, and reduced re-hospitalizations. We conclude that in CHF the early and personalized ambulatory follow-up based on congestion-guided treatment is effective to optimize management and maintain clinical stability in the post-discharge period.

RESUMO

We describe a case of commotio cordis in which the patient had an extensive cardiac evaluation, including ECGs, a coronary angiogram, a left ventriculogram, repeated echocardiography and cardiovascular MRI (CMRI). A healthy 17-year-old boy sustained an open-handed blow to the anterior part of the chest from a friend with whom he was playing. On admission ECG was performed that showed ST-T alterations and a TNI increase, with echocardiographic evidence of a localised pericardial effusion associated with a persistent myocardial blush at selective angiography. In addition, CMRI confirmed a local delayed enhancement in the same zone. An echocardiogram examination performed 30 days after discharge showed a complete disappearance of pericardial effusion and an improvement on ECG alterations. This is the first case report of a patient with commotio cordis, who did not show any arrhythmias and did not receive any resuscitation procedure, and was extensively studied by imaging methods.

RESUMO

Mortality from pulmonary embolism (PE) in pregnancy might be related to challenges in targeting the right population for prevention. Such targeting could help ensure that the correct diagnosis is suspected and adequately investigated, and allow the initiation of the timely and best possible treatment of this disease. In the literature to date only 18 case reports of thrombolysis in pregnant women with PE have been reported, and showed beneficial effects for both mother and fetus in terms of mortality and complications with acceptable bleeding risks. We present here the case of a pregnant patient with massive PE who underwent successful thrombolysis. A 26-year-old pregnant (at 24 weeks) woman was admitted 4 h after onset of sudden acute dyspnea and chest pain. An immediate electrocardiogram showed a typical S1-Q3-T3 pattern. The echocardiogram showed a distended right ventricle with free-wall hypokinesia and displacement of the interventricular septum toward the left ventricle. Thrombolysis with recombinant tissue plasminogen activator (alteplase 10 mg bolus, then 90 mg over 2 h) was administered. Pelvic examination and ultrasound showed regular fetal heart beat, and regular placental and liquid presence. No problems developed for the mother or fetus in the subsequent days or at discharge. In conclusion, in pregnant patients with life-threatening massive PE, thrombolytic therapy can be administered, and the use of echocardiographic, laboratory, and clinical data can be useful tools to achieve a rapid diagnosis and make a therapeutic decision, but additional studies need to be performed to further define its use.

RESUMO

INTRODUCTION: Hypertonic saline solution (HSS) and a moderate Na restriction plus high furosemide dose showed beneficial effects in compensated heart failure (HF), in short and long terms. The study was aimed to verify the effects of this combination on hospitalization time, readmissions and mortality in patients in New York Heart Association (NYHA) class III. METHOD: Chronic ischemic or nonischemic cardiomyopathy uncompensated patients with HF in NYHA III functional class with ejection fraction <40%, serum creatinine <2.5 mg/dL, blood urea nitrogen <60 mg/dL and reduced urinary volume were single-blind randomized in 2 groups: the first group received a 30-minute intravenous infusion of furosemide (250 mg) plus HSS (150 mL) twice daily and a moderate Na restriction (120 mmol); the second group received furosemide intravenous bolus (250 mg) twice a day, without HSS and a low Na diet (80 mmol); both groups received a fluid intake of 1000 mL/d. After discharge, the HSS group continued with 120 mmol Na/d; the second group continued with 80 mmol Na/d. RESULTS: A total of 1771 patients (881 HSS group and 890 without HSS group) met inclusion criteria: the first group (881 patients), compared with the second (890 patients), showed an increase in diuresis and serum Na levels, a reduction in hospitalization time (3.5 + 1 versus 5.5 + 1 days, P < 0.0001) and, during follow-up (57 + 15 months), a lower rate in readmissions (18.5% versus 34.2%, P < 0.0001) and mortality (12.9% versus 23.8%, P < 0.0001); the second group also showed a significant increase in blood urea nitrogen and serum creatinine. CONCLUSION: This study suggests that in-hospital HSS administration, combined with moderate Na restriction, reduces hospitalization time and that a moderate sodium diet restriction determines long-term benefit in patients with NYHA class III HF.

RESUMO

BACKGROUND: The aim of the study was to verify the effects of hypertonic saline solution (HSS) plus a high furosemide dose and light restriction of sodium intake compared with a high-dose infusion of furosemide alone on pulmonary capillary wedge pressure (PCWP), as determined by Doppler echocardiography and tissue Doppler imaging in patients suffering from decompensated heart failure. METHODS AND RESULTS: Consecutive patients in New York Heart Association functional class IV, unresponsive to oral high doses of furosemide up to 250-500 mg/d and/or combinations of diuretics, with ejection fraction <40%, serum creatinine <2 mg/dL, blood urea nitrogen ≤60 mg/dL, reduced urinary volume (<500 mL/24 h), and low natriuresis (<60 mEq/24 h) were randomized into 2 groups (double blind). The first group received a furosemide infusion (250 mg) plus HSS (150 mL 3.0% Na) bid and light Na restriction (120 mmol), and the second group received furosemide infusion (250 mg) twice daily, and low Na diet (80 mmol). The fluid intake of both groups was restricted (1 L/d). Body weight, whole-body bioelectrical impedance analysis (BIA), 24-hour urinary volume, and serum and urinary laboratory parameters were measured daily. Estimations of echocardiographic PCWP (Echo-PCWP) were detected on entry, 1 hour after concluding the initial treatment, and 6 days thereafter. A total of 133 patients (47 women and 86 men), aged 65-82 years, met the entry criteria.The HSS group revealed a significant increase in daily diuresis, natriuresis, and serum sodium compared with the furosemide group. Six days after treatment, renal function was significantly improved in the HSS group. Both groups showed a significant reduction in Echo-PCWP, but the HHS group revealed a faster reduction and significant lower values at 6 days compared with the group taking furosemide alone. We observed a positive correlation between values of Echo-PCWP and BNP and an inverse correlation between BIA parameters and Echo-PCWP. CONCLUSIONS: Our data show that the combination of high diuretic dose and HSS infusion plus light restriction in dietary sodium intake determine a more rapid and significant hemodynamic stabilization through the improvement of echo-PCWP, BNP levels, and BIA parameters than the group treated without HSS.

RESUMO

INTRODUCTION: The aim of this study was to assess the effect of thrombolysis versus heparin treatment on echocardiographic parameters and clinical outcome, during hospitalization and within the first 180 days after admission, in patients with first episode of submassive pulmonary embolism (SPE) and right ventricle dysfunction (RVD). METHODS: Consecutive patients (age, 18-75 years) with a first episode of SPE, symptoms onset since no more than 6 hours, normal blood pressure (>100 mm Hg), echocardiographic evidence of RVD and positive lung spiral computed tomography were double-blind randomized: 1 group received 100 mg of alteplase (10-mg bolus, followed by a 90-mg intravenous infusion over a period of 2 hours), while the other group received matching placebo. In addition to alteplase or placebo, both groups received an unfractionated heparin treatment. Echocardiogram was performed at admission, at 24, 48 and 72 hours, at discharge and at 3 and at 6 months after randomization. RESULTS: Seventy-two patients were included into the study; 37 were assigned to thrombolysis and 35 to placebo. Both groups were well matched with regard to features and clinical presentation. Thrombolysis group showed a significant early improvement of RV function compared with heparin group, and this improvement was observed also during the follow-up (180 days). The same group also showed significant reduction in clinical events during the hospitalization and follow-up. CONCLUSIONS: Our data suggest that, in hemodynamically stable patients with SPE, thrombolysis shows an earliest reduction of RVD and a more favorable trend in clinical outcome, so, it could merit consideration in SPE.

RESUMO

A 68-year-old man was referred to the emergency department 6 h after onset of sudden acute dyspnoea. Immediate ECG showed sinus tachycardia with the typical S1-Q3-T3 pattern and incomplete right bundle branch block. The echocardiogram showed the presence of mobile thrombus in the right atrium, a distended right ventricle with free wall hypokinesia and displacement of the interventricular septum towards the left ventricle. Lung spiral computed tomography (CT) showed bilateral pulmonary involvement and confirmed the picture of a thrombotic system in the right atrium and caval vein. Thrombolytic treatment with recombinant tissue plasminogen activator (rt-PA) and heparin (alteplase 10 mg bolus, then 90 mg over 2 h) was administered. Six hours after thrombolysis bleeding gums and significant reduction in platelet count (around 50,000) were observed. Heparin was discontinued and bivalirudin (0.1 mg/kg bolus and 1.75 mg/kg per h infusion) plus warfarin was initiated and continued for 5 days until the international normalised ratio (INR) was within the therapeutic range (2.0-3.0) for 2 consecutive days, with concomitant platelet count normalisation. Lung spiral and lower abdominal CT before discharge did not show the presence of clots in the pulmonary arteries of the right and left lung. This case suggests that bivalirudin could offer promise for use in patients with heparin-induced thrombocytopaenia (HIT) after thrombolysis for massive pulmonary embolism.

RESUMO

BACKGROUND: epidemiologic studies indicate that elevated heart rate (HR) is an independent risk factor for mortality and morbidity in patients (pts) with chronic heart failure (CHF). Clinical trials with ß-blockers suggest that HR reduction is an important mechanism of their benefit in pts with stable CHF. Pharmacologic inhibition of the I(f) current now provides the opportunity of pure HR reduction. The purpose of this study was to evaluate the impact of ''Off-Label'' use of ivabradine on exercise capacity, gas exchange, functional class, quality of life, and neurohormonal modulation in pts with ischemic CHF. METHODS: between January 2008 and June 2008, a graded maximal exercise test with respiratory gas analysis and an endurance test with constant workload corresponding to 85% of the peak VO(2) at the baseline and after 3 months were performed, and at the same times, N-terminal probrain natriuretic peptide (NT-proBNP) levels were also measured, in 60 pts (45 M, 15 F, mean age 52.7 ± 5.3 years), with stable ischemic CHF, New York Heart Association (NYHA) functional classes II (n = 35)-III (n = 25), with left ventricular ejection fraction (LVEF) ≤ 40%, randomized to a ''off-label'' ivabradine use (n = 30) and a control group (n = 30). RESULTS: the exercise capacity increased from 14.8 ± 2.5 to 28.2 ± 3.5 min (P < .0001) and the peak oxygen consumption tended to improve from 13.5 ± 1.3 to 17.9 ± 2.4 mL/kg per minute (P < .0001) in ivabradine group. Oxygen consumption at the anaerobic threshold (AT) increased from 11.9 ± 1.4 to 15.3 ± 1.4 mL/kg per minute (P < .0001). NTproBNP levels decreased from 2356 ± 2113 pg/mL to 1434 ± 1273 pg/mL (P = .045). No significant differences were found in control group at 3 months. The positive ivabradine effects were also associated with an improvement in the NYHA functional class and quality of life. CONCLUSION: the ''Off-Label'' use of ivabradine significantly improves the exercise capacity, gas exchange, functional heart failure class, quality of life, and neurohormonal modulation in pts with ischemic CHF.

RESUMO

BACKGROUND: Cardiopulmonary exercise testing with ventilatory expired gas analysis (CPET) has proven to be a valuable tool for assessing patients with chronic heart failure (CHF). The maximal oxygen uptake (peak V02) is used in risk stratification of patients with CHF. The minute ventilation-carbon dioxide production relationship (VE/VCO2 slope) has recently demonstrated prognostic significance in patients with CHF. METHODS: Between January 2006 and December 2007 we performed CPET in 184 pts (146 M, 38 F, mean age 59.8 +/- 12.9 years), with stable CHF (96 coronary artery disease, 88 dilated cardiomyopathy), in NYHA functional class II (n.107) - III (n.77), with left ventricular ejection fraction (LVEF) /= 35.6 and 25% in those with VE/VCO2 slope < 35.6 (log rank chi2: 67.03, p < 0.0001) and 66% in patients with peak VO2 12.2 ml/kg/min (log rank chi2: 50.98, p < 0.0001). One-year cardiac-related hospitalization was 77% in patients with VE/VCO2 slope >/= 32.5 and 23% in those with VE/VCO2 slope < 32.5 (log rank chi2: 133.80, p < 0.0001) and 63% in patients with peak VO2 12.3 ml/kg/min (log rank chi2: 72.86, p < 0.0001). The VE/VCO2 slope was demonstrated with receiver operating characteristic curve analysis to be equivalent to peak VO2 in predicting cardiac-related mortality (0.89 vs. 0.89). Although area under the receiver operating characteristic curve for the VE/VCO2 slope was greater than peak VO2 in predicting cardiac-related hospitalization (0.88 vs 0.82), the difference was no statistically significant (p = 0.13). CONCLUSION: These results add to the present body of knowledge supporting the use of CPET in CHF patients. The VE/VCO2 slope, as an index of ventilatory response to exercise, is an excellent prognostic parameter and improves the risk stratification of CHF patients. It is easier to obtain than parameters of maximal exercise capacity and is of equivalent prognostic importance than peak VO2.

RESUMO

BACKGROUND: beta-blockers in ST-segment elevation myocardial infarction (STEMI) are indicated for patients without a contraindication, particularly in patients with high heart rates (HR) or blood pressures. Epidemiological studies have shown that elevated HR represents a risk factor for cardiovascular morbidity. The study investigates the feasibility, tolerability, and the effects after 30 days of follow-up of ivabradine (IVA) versus metoprolol (METO) in early phases of anterior STEMI reperfused by percutaneous coronary intervention (PCI). METHODS AND RESULTS: Patients with a first anterior STEMI, Killip class I-II, an acceptable echocardiographic window, and admitted within 4hours of the onset of symptoms, with an ejection fraction <50%. METO or IVA, 12hours after PCI (double blind), were administered twice per day. Blood pressure (BP), heart rate (HR), electrocardiogram (ECG), and laboratory parameters were monitored during the study. At entry, day 10, day 30, and day 60, by echocardiography, the ESV, EDV, E/A ratio, E wave deceleration time, isovolumetric relaxation time were measured. A total of 155 (50 females, 105 males) patients were randomized in 2 groups: a group received METO (76 patients) 12hours after PCI and a group received IVA (79 patients) 12hours after PCI. The 2 groups were similar for clinical characteristics. No difference was evidenced in HR, systolic blood pressure, diastolic blood pressure, age (range, 39-73 years), sex, ejection fraction (EF), creatine kinase peak, between the 2 groups at entry. Both groups were similar for time to angiography and interventional procedures and number of vessels diseased. IVA group: the 79 patients showed 2 side effects and 5 readmissions: 4 for ischemic events and 1 for heart failure, and 1 sudden death; METO group: the 76 patients had 4 ischemic events, 2 side effects, and 1 patient died during re-acute MI (intrastent thrombosis) and 8 readmissions for heart failure signs. The systolic blood pressure and diastolic blood pressure showed a significant reduction in both groups, P < .0001, respectively), and significant lower values were observed in METO group, P=.0001). The HR was significantly reduced in both groups, P < .0001). IVA group showed a significant increase in EF, P=.0001, with concomitant reduction in ESV and EDV (P=.0001, and .048, respectively). The diastolic parameters were similar in both groups during study period. CONCLUSIONS: Our results suggest that ivabradine may be administered early (12hours after PCI) to patients with successful PCI for anterior STEMI with an impaired left ventricular function and high HR and sinus rhythm. A larger sample of patients and further studies are required to evaluate the effects of ivabradine on clinical end points.

RESUMO

BACKGROUND: A growing body of evidence suggests that the fluid accumulation plays a key role in the pathophysiology of heart failure (HF) and that the inflammatory and neurohormonal activation contribute strongly to the progression of this disorder. METHODS AND RESULTS: The study evaluated the long-term effects of 2 different sodium diets on cytokines neurohormones, body hydration and clinical outcome in compensated HF outpatients (New York Heart Association Class II). A total of 173 patients (105 males, mean age 72.5+/-7) recently hospitalized for worsening advanced HF and discharged in normal hydration and in clinical compensation were randomized in 2 groups (double blind). In Group 1, 86 patients received a moderate restriction in sodium (120mmol to 2.8g/day) plus oral furosemide (125 to 250mg bid); in Group 2, 87 patients: received a low-sodium diet (80mmol to 1.8g/day) plus oral furosemide (125 to 250mg bid). Both groups were followed for 12 months and the treatment was associated with a drink intake of 1000mL daily. Neurohormonal (brain natriuretic peptide, aldosterone, plasma rennin activity) and cytokines values (tumor necrosis factor-alpha, interleukin-6) were significantly reduced with a significant increase of the anti-inflammatory cytokine interleukin-10 at 12 months in normal, P < .0001) than low-sodium group. The low-sodium diet showed a significant activation of neurohormones and cytokines and worsening the body hydration, whereas moderate sodium restriction maintained dry weigh and improved outcome in the long term. CONCLUSIONS: Our results appear to suggest a surprising efficacy of a new strategy to improve the chronic diuretic response by increasing Na intake and limiting fluid intake. This counterintuitive approach underlines the need for a better understanding of factors that regulate sodium and water handling in chronic congestive HF. A larger sample of patients and further studies are required to evaluate whether this is due to the high dose of diuretic used or the low-sodium diet.

RESUMO

Studies have shown that patients with compensated heart failure (HF) receiving high diuretic doses associated with normal sodium diet and fluid intake restrictions demonstrated significant reductions in readmissions and mortality compared with those who received low-sodium diets, and over a 6-month observation period, a reduction in neurohormonal activation was also observed. The aim of this study was to evaluate the effects of different sodium diets associated with different diuretic doses and different levels of fluid intake on hospital readmissions and neurohormonal changes after 6-month follow-up in patients with compensated HF. Four hundred ten consecutive patients with compensated HF (New York Heart Association class II to IV) aged 53 to 86 years, with ejection fractions <35% and serum creatinine <2 mg/dl, were randomized into 8 groups: group A (n = 52): 1,000 ml/day of fluid intake, 120 mmol/day, and 250 mg furosemide twice daily; group B (n = 51): 1,000 ml/day of fluid intake, 120 mmol/day, and 125 mg furosemide twice daily; group C (n = 51): 1,000 ml/day fluid intake, 80 mmol/day, and 250 mg furosemide twice daily; group D (n = 51): 1,000 ml/day fluid intake, 80 mmol/day, and 125 mg furosemide twice daily; group E (n = 52): 2,000 ml/day fluid intake, 120 mmol/day, and 250 mg furosemide twice daily; group F (n = 50): 2,000 ml/day fluid intake, 120 mmol/day, and 125 mg furosemide twice daily; group G (n = 52): 2,000 ml/day fluid intake, 80 mmol/day, and 250 mg furosemide twice daily; and group H (n = 51): 2,000 ml/day fluid intake, 80 mmol/day, and 125 mg furosemide twice daily. All patients received the treatments >or=30 days after discharge and for 180 days afterward. Signs of HF, body weight, blood pressure, heart rate, laboratory parameters, electrocardiograms, echocardiograms, brain natriuretic peptide, aldosterone, and plasma renin activity were examined at baseline and 180 days later. Group A showed the best results, with a significant reduction (p <0.001) in readmissions, brain natriuretic peptide, aldosterone, and plasma renin activity compared with the other groups during follow-up (p <0.001). In conclusion, these data suggest that the combination of a normal-sodium diet with high diuretic doses and fluid intake restriction, compared with different combinations of sodium diets with more modest fluid intake restrictions and conventional diuretic doses, leads to reductions in readmissions, neurohormonal activation, and renal dysfunction.

RESUMO

A 31-year-old man (175 cm, 82 kg) was referred to the emergency department 2 h after the sudden onset of acute dyspnea. Immediate ECG showed sinus tachycardia with ST elevations from V1 through V2 and a diagnosis of septal acute myocardial infarction was made. ECG on admission to the cardiology department showed the same results plus the S1-Q3-T3 pattern. Echocardiogram revealed a normally contracting left ventricle, a distended right ventricle with free wall hypokinesia and displacement of the interventricular septum towards the left ventricle. Thrombolytic therapy with tenecteplase 8000 IU and heparin 5000 IU was administered 5-10 min after hospitalisation and the patient was haemodynamically stable 30 min later. Echocardiogram performed 12 h after thrombolysis showed a normal left ventricle and a less distended right ventricle. Lung spiral computed tomography (CT) and lower abdominal CT on the fourth day showed large emboli in the inferior pulmonary arteries of the right and left lung. Rarely, massive pulmonary embolism may mimic anteroseptal acute myocardial infarction on ECG and this case demonstrates the utility of echocardiography for a differential diagnosis, as well as the efficacy of tenecteplase for thrombolytic therapy.

RESUMO

The aim of the present study was to evaluate the effects of a normal-sodium (120 mmol sodium) diet compared with a low-sodium diet (80 mmol sodium) on readmissions for CHF (congestive heart failure) during 180 days of follow-up in compensated patients with CHF. A total of 232 compensated CHF patients (88 female and 144 male; New York Heart Association class II-IV; 55-83 years of age, ejection fraction <35% and serum creatinine <2 mg/dl) were randomized into two groups: group 1 contained 118 patients (45 females and 73 males) receiving a normal-sodium diet plus oral furosemide [250-500 mg, b.i.d. (twice a day)]; and group 2 contained 114 patients (43 females and 71 males) receiving a low-sodium diet plus oral furosemide (250-500 mg, b.i.d.). The treatment was given at 30 days after discharge and for 180 days, in association with a fluid intake of 1000 ml per day. Signs of CHF, body weight, blood pressure, heart rate, laboratory parameters, ECG, echocardiogram, levels of BNP (brain natriuretic peptide) and aldosterone levels, and PRA (plasma renin activity) were examined at baseline (30 days after discharge) and after 180 days. The normal-sodium group had a significant reduction (P<0.05) in readmissions. BNP values were lower in the normal-sodium group compared with the low sodium group (685+/-255 compared with 425+/-125 pg/ml respectively; P<0.0001). Significant (P<0.0001) increases in aldosterone and PRA were observed in the low-sodium group during follow-up, whereas the normal-sodium group had a small significant reduction (P=0.039) in aldosterone levels and no significant difference in PRA. After 180 days of follow-up, aldosterone levels and PRA were significantly (P<0.0001) higher in the low-sodium group. The normal-sodium group had a lower incidence of rehospitalization during follow-up and a significant decrease in plasma BNP and aldosterone levels, and PRA. The results of the present study show that a normal-sodium diet improves outcome, and sodium depletion has detrimental renal and neurohormonal effects with worse clinical outcome in compensated CHF patients. Further studies are required to determine if this is due to a high dose of diuretic or the low-sodium diet.

RESUMO

The aim of the present study was to evaluate the safety and efficacy of the combination of indomethacin and statin compared with indomethacin plus placebo in patients with a first episode of pericarditis. A total of 55 consecutive patients with acute pericarditis were randomized in a double-blind manner into two groups: group 1 (statin group) was treated with 150 mg of indomethacin plus 10 mg of rosuvastatin, and group 2 (placebo group) was treated with 150 mg of indomethacin plus placebo. Both groups received treatment up to the normalization of inflammation markers and for the following week. Clinical and laboratory assessments [white cell count, ESR (erythrocyte sedimentation rate) and CRP (C-reactive protein), troponin I, creatine kinase and brain natriuretic peptide plasma levels], ECG and echocardiogram were performed at baseline and daily up to discharge. All of the patients were followed as outpatients for 3 months to evaluate any recurrence of pericarditis. The two groups were similar in age, sex and laboratory parameters [group 1 (the statin group), n=28 patients; gender, 18 male and ten female; and age, 29.5+/-5.7 years; group 2 (placebo group), n=27 patients; gender, 16 male/11 female; and age, 29.2+/-4.8 years]. The statin group, when compared with the placebo group, had a significantly faster reduction in CRP values (5.0+/-1.0 compared with 6.0+/-2.0 days respectively; P=0.022), ST segment normalization (3.5+/-1.0 compared with 4.5+/-1.0 days respectively; P=0.001), pericardial effusion (4.5+/-1.0 compared with 5.5+/-1.0 days respectively; P=0.001) and ESR (5.0+/-1 compared with 6.0+/-2 days respectively; P=0.022). Our results show that the combination of statin and indomethacin treatment in patients with acute pericarditis is feasible, with a significant reduction in inflammatory markers and a favourable trend in hospitalization time (5.5+/-2.0 compared with 6.5+/-2.0 days respectively; P=0.069). However, these preliminary findings require further studies in a larger sample of patients.

RESUMO

Arterial hypertension is a significant cause of end-stage renal failure; effective treatment of hypertensive patients reduces the rate of progression of this disorder. ss-Blockers, particularly nonselective agents, are associated with deterioration of renal function in patients with chronic renal failure. Previous studies on the interaction of the beta1-selective adrenergic antagonist bisoprolol with kidney function have been performed only acutely and over the short term. This study was designed to evaluate the antihypertensive efficacy and effects on renal hemodynamics and function of bisoprolol during medium-term (6 mo) treatment of patients with mild to moderate essential hypertension. After a 2-wk run-in period on placebo, 87 consecutive hypertensive patients (46 men, 41 women) according to ESH-ESC (European Society of Hypertension/European Society of Cardiology) guidelines, aged from 27 to 64 y (mean age, 50+/-11 y), without renal or cardiovascular disease, were enrolled and assigned to treatment with bisoprolol 5 mg once daily for 6 mo. At recruitment and at 6 mo after treatment, renal function was assessed and renal hemodynamics evaluated in all patients through radioisotope studies. The medium-term effects of bisoprolol included a significant reduction in blood pressure and heart rate (P<.001) without significant adverse drug reactions. Moreover, bisoprolol produced no alteration in renal function or hemodynamics, or in cardiac output. Data presented here indicate that bisoprolol 5 mg given once daily to treat patients with mild to moderate essential hypertension is effective and safe for treatment and for preservation of renal performance when given on a medium-term basis.

RESUMO

BACKGROUND: There are several new strategies proposed to improve the outcome of patients with ST-elevation myocardial infarction (STEMI). One approach is the resurgent use of facilitated percutaneous coronary interventions (PCI). Until recently, deciding whether immediate PCI after combined treatment (facilitated PCI) is more appropriate than delayed PCI (short time) has not been investigated. The aim of this study, therefore, was to investigate the outcomes in patients initially successfully treated pharmacologically and immediate PCI < 2 hr, and in patients initially successfully treated with pharmacological therapy and with delayed PCI (12-72 h). METHODS: 451 reperfused STEMI patients, aged 18 to 75 years, class I-II Killip, with an acceptable echocardiographic window and admitted within 12 hs of the onset of symptoms were randomized into two groups. All patients had to have successful reperfusion, to receive the combination of a standard tirofiban infusion or abciximab plus half dose rtPA. Thereafter, patients were sub-grouped as follows:group 1 (immediate PCI) patients had PCI within 2 h; and group 2 (delayed PCI) patients in which PCI was performed after 12 hs and within 72 hs. RESULTS: The 225 reperfused (immediate-PCI) and 226 reperfused (delayed-PCI) patients (time from randomization to PCI 165 +/- 37 min in immediate PCI versus 45.1 +/- 20.2 h in delayed PCI group) showed similar results in ejection fraction, CK release and patency of the IRA. In addition, the delayed PCI group showed a significant reduction in ischemic events, restenosis and bleedings (P = 0.005, 0.01, 0.01 respectively) and significant reduced angiographic evidence of thrombus formation in the infarction-related artery (IRA) (p = 0.001). CONCLUSION: Our data suggest the safety and possible use of delayed facilitated PCI in patients with STEMI, and that delayed PCI in patients treated with combined lytic and IIb/IIIa inhibitors appears to be as effective and possibly superior (reduced ischemic events and repeat PCI) as immediate PCI. The patients in this study were successfully reperfused, with TIMI-3 flow and our data may not apply to patients with TIMI 0-2 flow. This strategy could allow transferring the reperfused patients and performing PCI after hours < 72 hours and not immediately, thereby reducing the number of urgent PCI and costs, obtaining similar results, but mostly causing less discomfort to the patient. Our results had to be interpreted with caution, because current guidelines do not recommend the combined therapy, but suggest further studies. The study was aimed to investigate the outcomes in patients initially successfully treated pharmacologically and immediate PCI < 2 h, and in patients initially successfully treated with pharmacological therapy and delayed PCI (12-72 h). All patients had to have successful reperfusion, to receive the combination of a standard abciximab or tirofiban infusion plus half dose rtPA. Similar results were observed in both groups. Delayed PCI group showed a significant lower incidence in restenosis (0.01), minor bleedings (0.005), ischemic events (0.01) and a reduced angiographic evidence of thrombus formation in IRA (0.001). Our data suggest the safety and possible use of delayed facilitated PCI in patients with STEMI. Our results had to be interpreted with caution, because current guidelines do not recommend the combined therapy, but suggest further studies.
