RESUMO

BACKGROUND: Hyperuricemia is associated with a poorer prognosis in heart failure (HF) patients. Benefits of hyperuricemia treatment with allopurinol have not yet been confirmed in clinical practice. The aim of our work was to assess the benefit of allopurinol treatment in a large cohort of HF patients. METHODS: The prospective acute heart failure registry (AHEAD) was used to select 3160 hospitalized patients with a known level of uric acid (UA) who were discharged in a stable condition. Hyperuricemia was defined as UA ≥500 µmoL/L and/or allopurinol treatment at admission. The patients were classified into three groups: without hyperuricemia, with treated hyperuricemia, and with untreated hyperuricemia at discharge. Two- and five-year all-cause mortality were defined as endpoints. Patients without hyperuricemia, unlike those with hyperuricemia, had a higher left ventricular ejection fraction, a better renal function, and higher hemoglobin levels, had less frequently diabetes mellitus and atrial fibrillation, and showed better tolerance to treatment with angiotensin-converting enzyme inhibitors/angiotensin receptor blockers and/or beta-blockers. RESULTS: In a primary analysis, the patients without hyperuricemia had the highest survival rate. After using the propensity score to set up comparable groups, the patients without hyperuricemia had a similar 5-year survival rate as those with untreated hyperuricemia (42.0% vs 39.7%, P = 0.362) whereas those with treated hyperuricemia had a poorer prognosis (32.4% survival rate, P = 0.006 vs non-hyperuricemia group and P = 0.073 vs untreated group). CONCLUSION: Hyperuricemia was associated with an unfavorable cardiovascular risk profile in HF patients. Treatment with low doses of allopurinol did not improve the prognosis of HF patients.

RESUMO

Giant cell myocarditis is known as a rare and frequently fatal type of myocarditis that is usually characterized by progressive congestive heart failure and frequent ventricular arrhythmias. We report a rare case of giant cell myocarditis in a 64-year-old previously healthy woman. The case was complicated by the rapid development of progressive acute heart failure, which required the comprehensive care of our heart team. Using a broad spectrum of therapeutic approaches, the patient successfully underwent heart transplantation.

RESUMO

BACKGROUND: Infectious complications (IC) are one of the main causes of worsening prognosis after long-term ventricular assist device (LVAD) implantation. Procalcitonin (PCT) is widely used for diagnosis of a bacterial infection. The objective of this study was to assess PCT dynamics after LVAD surgery and their relationship to the infectious complications. METHODS: A total of 25 consecutive patients indicated for LVAD implantation as a bridge to heart transplant were included. Procalcitonin levels were prospectively assessed before surgery and during the postoperative period (day 1, 2, 14 and 30). Values were compared according to the presence of IC. RESULTS: Procalcitonin levels were low before surgery, raised significantly within 1st and 2nd day after operation and decreased in the 14th and 30th days back to the baseline. There was no significant difference in PCT values between patients with or without IC as well as with or without right ventricle assist device (RVAD). Acute renal failure (ARF) increased PCT significantly only 14 days after LVAD implantation. In patients with ARF and/or RVAD we observed significantly higher PCT values in the 2nd, 14th and 30th day after operation. In subjects with IC and/or ARF and/or RVAD we also observed significantly elevated PCT concentrations 2 and 14 days after surgery. CONCLUSIONS: Our data show that the ability of PCT to detect IC in patients after LVAD implantation is limited and its concentrations more likely correlate with postoperative complications in general.

RESUMO

BACKGROUND: Obesity is clearly associated with increased morbidity and mortality rates. However, in patients with acute heart failure (AHF), an increased BMI could represent a protective marker. Studies evaluating the "obesity paradox" on a large cohort with long-term follow-up are lacking. METHODS: Using the AHEAD database (a Czech multi-centre database of patients hospitalised due to AHF), 5057 patients were evaluated; patients with a BMI <18.5 kg/m2 were excluded. All-cause mortality was compared between groups with a BMI of 18.5-25 kg/m2 and with BMI >25 kg/m2. Data were adjusted by a propensity score for 11 parameters. RESULTS: In the balanced groups, the difference in 30-day mortality was not significant. The long-term mortality of patients with normal weight was higher than for those who were overweight/obese (HR, 1.36; 95% CI, 1.26-1.48; p<0.001)). In the balanced dataset, the pattern was similar (1.22; 1.09-1.39; p<0.001). A similar result was found in the balanced dataset of a subgroup of patients with de novo AHF (1.30; 1.11-1.52; p = 0.001), but only a trend in a balanced dataset of patients with acute decompensated heart failure. CONCLUSION: These data suggest significantly lower long-term mortality in overweight/obese patients with AHF. The results suggest that at present there is no evidence for weight reduction in overweight/obese patients with heart failure, and emphasize the importance of prevention of cardiac cachexia.

RESUMO

Clinical data on optimal management of mechanical complications of myocardial infarction are lacking. We retrospectively evaluated the effect of intra-aortic balloon pump (IABP) on 30-day survival in patients with postinfarction ventricular septal rupture (VSR, n = 55) or acute mitral regurgitation (MR, n = 26) who developed either cardiogenic shock (n = 46) or severe hemodynamic instability that did not fulfill the criteria of shock (n = 35). IABP was inserted in 83% of the patients with shock and 57% of those without shock. Thirty-five (76%) patients with shock and all unstable patients survived until surgical repair, which was performed within a median (interquartile range) of 1 (1 to 2) and 9 (2 to 18) days from the onset of the complication (p <0.001). All patients who did not undergo the operation died within 3 days. Although MR presented more acutely, the patients' outcomes were similar to those with VSR. IABP support reduced 30-day mortality in the patients with shock (61% vs 100%, p = 0.04) but not in the patients without shock (20% vs 27%, p = 0.7). The benefit of IABP support in the shock cohort was driven mainly by reduction of preoperative mortality (11% vs 88%, p <0.001). Early progression of cardiogenic shock and unperformed surgery were the only independent predictors of 30-day mortality (hazard ratio 3.4, 95% confidence interval 1.5 to 8 and hazard ratio 5.1, 95% confidence interval 2.2 to 11, respectively; p = 0.004 and p <0.001, respectively). In conclusion, we suggest that all patients with postinfarction VSR or acute MR with signs of cardiogenic shock should immediately receive IABP as a bridge to emergent surgical repair. In contrast, hemodynamically unstable patients without shock may be first stabilized by medical therapy, without additional benefit of IABP, before they undergo cardiac surgery.

RESUMO

Severe aortic stenosis (AS) has a poor prognosis when associated with left ventricular dysfunction and congestive heart failure. Despite a relatively high operative mortality, most patients with severe AS and a depressed left ventricular ejection fraction (LVEF) should be considered candidates for aortic valve replacement. The CentriMag left ventricular assist system (Levitronix) can be used for perioperative or postcardiotomy circulatory support for the failing heart. In this case report, we report the successful use of the Levitronix CentriMag device as perioperative support in a high-risk patient with severe AS, significant mitral insufficiency, and a poor LVEF with advanced organ failure.

RESUMO

BACKGROUND: Statins have been proved to be effective in reduction of mortality and morbidity when started in the early secondary prevention in stabilized patients after acute coronary syndrome (ACS). The safety and efficacy of statin administration directly in the first-line therapy in unstable ACS patients is not clear. The aim of our study was, therefore, to assess the effect of statin treatment initiated immediately at hospital admission of patients with ACS. METHODS: The trial was stopped prematurely after enrollment of one hundred and fifty-six patients with ACS that were randomized at admission to fluvastatin 80 mg (N = 78) or placebo (N = 78). Study medication was administered immediately after randomization and then once daily for 30 days; all patients were then encouraged to continue in open-label statin therapy and at the end of one-year follow-up 75% in the fluvastatin group and 78% in the placebo group were on statin therapy. RESULTS: We did not demonstrate any difference between groups in the level of C-reactive protein, interleukin 6, and pregnancy-associated plasma protein A on Day 2 and Day 30 (primary endpoint). Fluvastatin-therapy, however, significantly reduced one-year occurrence of major adverse cardiovascular events (11.5% vs. 24.4%, odds ratio (OR) 0.40, 95% CI 0.17-0.95, P = 0.038). This difference was caused mainly by reduction of recurrent symptomatic ischemia (7.7% vs. 20.5%, OR 0.32, 95% CI 0.12-0.88, P = 0.037). CONCLUSIONS: This study failed to prove the effect of fluvastatin given as first-line therapy of ACS on serum markers of inflammation and plaque instability. Fluvastatin therapy was, however, safe and it may reduce cardiovascular event rate that supports immediate use of a statin in patients admitted for ACS. TRIAL REGISTRATION: NCT00171275.
