Opinion statement Cardiovascular complications are frequently encountered in the HIV-infected population. Cardiac care providers should implement
appropriate preventive, screening, and therapeutic strategies to maximize survival and quality of life in this increasingly
treatable, chronic disease. All HIV-infected individuals should undergo periodic cardiac evaluation, including echocardiography,
in order to identify subclinical cardiac dysfunction. Left ventricular (LV) dysfunction can result from, or be exacerbated
by, a variety of treatable infectious, endocrine, nutritional, and immunologic disorders. Aggressive diagnosis and treatment
of these conditions may lead to improvement or even normalization of myocardial function. Endomyocardial biopsy should be
considered to direct etiology-specific therapy. Standard measures for the prevention and treatment of congestive heart failure
are recommended for HIV-infected patients. Afterload reduction with angiotensin-converting enzyme inhibitors may be indicated
for patients with elevated afterload and preclinical LV dysfunction diagnosed by echocardiogram. However, judicious drug selection
and titration are necessary in this cohort of patients with frequent autonomic dysfunction, at risk for a number of potentially
lethal drug interactions. Carnitine, selenium, and multivitamin supplementation should be considered, especially in those
with wasting or diarrhea syndromes. Monthly intravenous immunoglobulin (IVIG) infusions have been demonstrated to preserve
LV parameters in HIV-infected children; ventricular recovery has been documented in some children with recalcitrant HIV-related
cardiomyopathy following IVIG infusion. We support the use of immunomodulatory therapy in the pediatric population, and look
forward to further study into the efficacy and broader application of this approach. Highly active antiretroviral therapy
(HAART) may be associated with dyslipidemia and the metabolic syndrome. This should be treated with dietary and possibly with
pharmacologic interventions. Drug interactions need to be considered when instituting pharmacologic therapies. Pericardial
effusions are often seen in patients with advanced HIV infection. Asymptomatic effusions are most often nonspecific in nature,
related to the proinflammatory milieu found in advanced AIDS. Nonspecific effusions are a marker of advanced disease and do
not require exhaustive etiologic evaluation. In contrast, large or symptomatic effusions are often associated with infection
or malignancy, and warrant thorough investigation and etiology-specific treatment. 相似文献

BackgroundThe relationship between the presence of pleural and pericardial effusion in reference to hemodynamic parameters remains unclear in ambulatory patients with pulmonary hypertension (PH).MethodsConsecutive patients who underwent right catheterization (RHC) for the evaluation of pulmonary hypertension were enrolled. Point-of- care ultrasound was performed prior to the RHC to determine the presence of pleural effusion and pericardial effusion. We conducted a cross-sectional study to determine the association between presence of pericardial and pleural effusion with pulmonary hemodynamic variables.ResultsTwenty-five (78.1%) of 32 patients had evidence of PH by RHC. Mean pulmonary artery pressure of the population was 40.6 mmHg, and 68% (17/25) had WHO group I PH. Six (24.0%) of 25 PH patients had pleural effusions identified, of which 4 out of 6 (66.7%) had a pulmonary artery wedge pressure >15 mmHg. Eleven (44.0%) of the 25 PH patients were also found to have pericardial effusions, and most of those patients 10/11(90.9%) had an elevated right atrial pressure >10 mmHg. The presence of a pleural effusion was associated with a pulmonary artery wedge pressure >15 mmHg (p = 0.032) and the presence of a pericardial effusion was associated with a right atrial pressure >10 mmHg (p = 0.004). Detection of pleural effusion had a poor positive predictive value (67%) for the presence of pulmonary venous hypertension, whereas presence of a pericardial effusion was highly predictive (89%) of the presence of systemic venous hypertension.ConclusionsSystemic venous hypertension was associated with the presence of pericardial effusions, while pulmonary venous hypertension is associated with pleural effusion development in ambulatory patients with pulmonary hypertension. 相似文献

BackgroundMyocardial fibrosis is a key mechanism of left ventricular decompensation in aortic stenosis and can be quantified using cardiovascular magnetic resonance (CMR) measures such as extracellular volume fraction (ECV%). Outcomes following aortic valve intervention may be linked to the presence and extent of myocardial fibrosis.ObjectivesThis study sought to determine associations between ECV% and markers of left ventricular decompensation and post-intervention clinical outcomes.MethodsPatients with severe aortic stenosis underwent CMR, including ECV% quantification using modified Look-Locker inversion recovery–based T1 mapping and late gadolinium enhancement before aortic valve intervention. A central core laboratory quantified CMR parameters.ResultsFour-hundred forty patients (age 70 ± 10 years, 59% male) from 10 international centers underwent CMR a median of 15 days (IQR: 4 to 58 days) before aortic valve intervention. ECV% did not vary by scanner manufacturer, magnetic field strength, or T1 mapping sequence (all p > 0.20). ECV% correlated with markers of left ventricular decompensation including left ventricular mass, left atrial volume, New York Heart Association functional class III/IV, late gadolinium enhancement, and lower left ventricular ejection fraction (p < 0.05 for all), the latter 2 associations being independent of all other clinical variables (p = 0.035 and p < 0.001). After a median of 3.8 years (IQR: 2.8 to 4.6 years) of follow-up, 52 patients had died, 14 from adjudicated cardiovascular causes. A progressive increase in all-cause mortality was seen across tertiles of ECV% (17.3, 31.6, and 52.7 deaths per 1,000 patient-years; log-rank test; p = 0.009). Not only was ECV% associated with cardiovascular mortality (p = 0.003), but it was also independently associated with all-cause mortality following adjustment for age, sex, ejection fraction, and late gadolinium enhancement (hazard ratio per percent increase in ECV%: 1.10; 95% confidence interval [1.02 to 1.19]; p = 0.013).ConclusionsIn patients with severe aortic stenosis scheduled for aortic valve intervention, an increased ECV% is a measure of left ventricular decompensation and a powerful independent predictor of mortality. 相似文献

Background
Troponins may be elevated in patients with pneumonia, but associations with myocardial infarction (MI) and with platelet activation are still undefined.Objectives
The aim of this study was to investigate the relationship between troponin elevation and in vivo markers of platelet activation in the early phase of hospitalization of patients affected by community-acquired pneumonia.Methods
A total of 278 consecutive patients hospitalized for community-acquired pneumonia, who were followed up until discharge, were included. At admission, platelet activation markers such as plasma soluble P-selectin, soluble CD40 ligand, and serum thromboxane B2 (TxB2) were measured. Serum high-sensitivity cardiac troponin T levels and electrocardiograms were obtained every 12 and 24 h, respectively.Results
Among 144 patients with elevated high-sensitivity cardiac troponin T, 31 had signs of MI and 113 did not. Baseline plasma levels of soluble P-selectin and soluble CD40 ligand and serum TxB2 were significantly higher in patients who developed signs of MI. Logistic regression analysis showed plasma soluble CD40 ligand (p < 0.001) and soluble P-selectin (p < 0.001), serum TxB2 (p = 0.030), mean platelet volume (p = 0.037), Pneumonia Severity Index score (p = 0.030), and ejection fraction (p = 0.001) to be independent predictors of MI. There were no significant differences in MI rate between the 123 patients (45%) taking aspirin (100 mg/day) and those who were not aspirin treated (12% vs. 10%; p = 0.649). Aspirin-treated patients with MIs had higher serum TxB2 compared with those without MIs (p = 0.005).Conclusions
MI is an early complication of pneumonia and is associated with in vivo platelet activation and serum TxB2 overproduction; aspirin 100 mg/day seems insufficient to inhibit thromboxane biosynthesis. (MACCE in Hospitalized Patients With Community-acquired Pneumonia; NCT01773863) 相似文献20.
非心脏手术患者围手术期心肌梗死的处理 总被引:1,自引:0,他引:1
围手术期心肌梗死是拟行非心脏手术的患者发病和死亡的主要原因。而围手术期心肌梗死的发生率正随着外科手术与麻醉的发展和拟行外科手术人数的增多而逐渐升高。尽管有很多近期的研究、综述和指南均把非心脏手术围手术期心脏危险的评估,心肌缺血和心肌梗死的预防作为关注焦点,但有关围手术期心肌梗死一旦发生时相应处理方法的研究和报道仍为数不多。因此就主要对外科手术背景备件下的围手术期心肌梗死的流行病学和其可能的发生机制等进行介绍,同时对其诊断与治疗重点进行探讨。 相似文献
