Indicators of poor prognosis of acute pericarditis.

BACKGROUND: The clinical search for indicators of poor prognosis of acute pericarditis may be useful for clinical triage of patients at high risk of specific causal conditions or complications. The aim of the present article is to assess the relationship between clinical features at presentation and specific causes or complications. METHODS AND RESULTS: A total of 453 patients aged 17 to 90 years (mean age 52+/-18 years, 245 men) with acute pericarditis (post-myocardial infarction pericarditis was excluded) were prospectively evaluated from January 1996 to August 2004. A specific cause was found in 76 of 453 patients (16.8%): autoimmune in 33 patients (7.3%), neoplastic in 23 patients (5.1%), tuberculous in 17 patients (3.8%), and purulent in 3 patients (0.7%). In multivariable analysis, women (hazard ratio [HR] 1.67, 95% confidence interval [CI] 1.03 to 2.70; P=0.036) and patients with fever >38 degrees C (HR 3.56, 95% CI 1.82 to 6.95; P<0.001), subacute course (HR 3.97, 95% CI 1.66 to 9.50; P=0.002), large effusion or tamponade (HR 2.15, 95% CI 1.09 to 4.23; P=0.026), and failure of aspirin or of nonsteroidal anti-inflammatory drugs (HR 2.50, 95% CI 1.28 to 4.91; P=0.008) were at increased risk of specific causal conditions. After a mean follow-up of 31 months, complications were detected in 95 patients (21.0%): recurrences in 83 patients (18.3%), tamponade in 14 patients (3.1%), and constriction in 7 patients (1.5%). In multivariable analysis, women (HR 1.65, 95% CI 1.08 to 2.52; P=0.020) and patients with large effusion or tamponade (HR 2.51, 95% CI 1.37 to 4.61; P=0.003) and failure of aspirin or of nonsteroidal anti-inflammatory drugs (HR 5.50, 95% CI 3.56 to 8.51; P<0.001) were at increased risk of complications. CONCLUSIONS: Specific clinical features (fever >38 degrees C, subacute course, large effusion or tamponade, and aspirin or NSAID failure) may be useful to identify higher risk of specific causal conditions and complications.

Colchicine in addition to conventional therapy for acute pericarditis: results of the COlchicine for acute PEricarditis (COPE) trial.

BACKGROUND: Colchicine is effective and safe for the treatment and prevention of recurrent pericarditis and might ultimately serve as the initial mode of treatment, especially in idiopathic cases. The aim of this work was to verify the safety and efficacy of colchicine as an adjunct to conventional therapy for the treatment of the first episode of acute pericarditis. METHODS AND RESULTS: A prospective, randomized, open-label design was used. A total of 120 patients (mean age 56.9+/-18.8 years, 54 males) with a first episode of acute pericarditis (idiopathic, viral, postpericardiotomy syndromes, and connective tissue diseases) were randomly assigned to conventional treatment with aspirin (group I) or conventional treatment plus colchicine 1.0 to 2.0 mg for the first day and then 0.5 to 1.0 mg/d for 3 months (group II). Corticosteroid therapy was restricted to patients with aspirin contraindications or intolerance. The primary end point was recurrence rate. During the 2873 patient-month follow-up, colchicine significantly reduced the recurrence rate (recurrence rates at 18 months were, respectively, 10.7% versus 32.3%; P=0.004; number needed to treat=5) and symptom persistence at 72 hours (respectively, 11.7% versus 36.7%; P=0.003). After multivariate analysis, corticosteroid use (OR 4.30, 95% CI 1.21 to 15.25; P=0.024) was an independent risk factor for recurrences. Colchicine was discontinued in 5 cases (8.3%) because of diarrhea. No serious adverse effects were observed. CONCLUSIONS: Colchicine plus conventional therapy led to a clinically important and statistically significant benefit over conventional treatment, decreasing the recurrence rate in patients with a first episode of acute pericarditis. Corticosteroid therapy given in the index attack can favor the occurrence of recurrences.

Colchicine as first-choice therapy for recurrent pericarditis: results of the CORE (COlchicine for REcurrent pericarditis) trial.

BACKGROUND: Colchicine seems to be a good drug for treating recurrences of pericarditis after conventional treatment failure, but no clinical trial has tested the effects of colchicine as first-line drug for the treatment of the first recurrence of pericarditis. METHODS: A prospective, randomized, open-label design was used to investigate the safety and efficacy of colchicine therapy as adjunct to conventional therapy for the first episode of recurrent pericarditis. Eighty-four consecutive patients with a first episode of recurrent pericarditis were randomly assigned to receive conventional treatment with aspirin alone or conventional treatment plus colchicine (1.0-2.0 mg the first day and then 0.5-1.0 mg/d for 6 months). When aspirin was contraindicated, prednisone (1.0-1.5 mg/kg daily) was given for 1 month and then was gradually tapered. The primary end point was the recurrence rate. Intention-to-treat analyses were performed by treatment group. RESULTS: During 1682 patient-months (mean follow-up, 20 months), treatment with colchicine significantly decreased the recurrence rate (actuarial rates at 18 months were 24.0% vs 50.6%; P = .02; number needed to treat = 4.0; 95% confidence interval 2.5-7.1) and symptom persistence at 72 hours (10% vs 31%; P = .03). In multivariate analysis, previous corticosteroid use was an independent risk factor for further recurrences (odds ratio, 2.89; 95% confidence interval, 1.10-8.26; P = .04). No serious adverse effects were observed. CONCLUSION: Colchicine therapy led to a clinically important and statistically significant benefit over conventional treatment, decreasing the recurrence rate in patients with a first episode of recurrent pericarditis.

Relation of acute pericardial disease to malignancy.

Neoplastic etiology was found in 33 of 450 patients with acute pericardial disease (7.3%). Acute pericardial disease was the first manifestation of previously unknown malignancies in 18 of 450 patients (4.0%), and lung cancer was the most common malignancy (72.2%, p = 0.02). The following clinical characteristics were associated with a greater probability of a neoplastic etiology: a history of malignancy (odds ratio [OR] 19.8), cardiac tamponade at presentation (OR 7.0), a lack of response to nonsteroidal anti-inflammatory drugs, and recurrent or incessant pericarditis (OR 10.0). A similar prognosis was found in patients with or without a history of known cancer.

A clinical approach for cardiovascular monitoring of HIV-infected patients. Results from an observational cohort study.

BACKGROUND: HIV infection is one of the leading causes of acquired heart disease. Because of its high diffusion, systematic echocardiographic monitoring has been proposed to exclude cardiovascular involvement in these patients. The aim of this study was to evaluate an alternative clinical approach by which echocardiographic screening is limited to patients with a clinical suspicion of heart disease. METHODS: We studied 2030 consecutive HIV-infected patients admitted to a tertiary referral hospital (group A). History, physical examination, ECG, and chest X-ray were used to screen HIV-infected patients for cardiovascular involvement. Selected patients were extensively studied, first of all by echocardiography. Cardiovascular and non-cardiovascular deaths were recorded: RESULTS: Cardiovascular involvement was clinically suspected in 201 patients (9.9%; group B). Among them a higher extracardiac mortality was found in presence of pericardial disease (odds ratio [OR] 4.27, 95% confidence interval [CI] 2.01-9.09), while a higher cardiovascular mortality was recorded for patients with cardiomyopathy or myocarditis (OR 2.72, 95% CI 1.09-6.81), and right ventricular dysfunction and/or pulmonary hypertension (OR 4.67, 95% CI 1.44-15.2). Compared with group A, patients in group B had a significantly increased cardiac death rate (0.114 vs 0.018, p < 0.001). A positive echocardiogram slightly increased this rate (from 0.114 to 0.164, p = NS), whereas a negative echocardiogram significantly decreased the cardiac death rate (0.015 vs 0.164, p = 0.004). CONCLUSIONS: Clinical selection of HIV-infected patients with suspected cardiovascular involvement may help identify patients with higher frequency of cardiovascular involvement. Among these patients, echocardiography may be a useful screening tool in those at high risk for cardiovascular death.

Recurrent pain without objective evidence of disease in patients with previous idiopathic or viral acute pericarditis.

Recurrent pain without clinical evidence of acute pericarditis was recorded in 27 of 275 patients (9.8%; mean age 55.6 +/- 16.0 years, female/male ratio 20/7) with previous viral or idiopathic acute pericarditis. Female gender (odds ratio [OR] 4.3, 95% confidence interval [CI] 1.8 to 10.6), previous use of corticosteroids (OR 5.2, 95% CI 2.2 to 12.3), and previous recurrent pericarditis (OR 3.7, 95% CI 1.3 to 10.2) were identified as risk factors for this syndrome. After a mean follow-up of 40 months, a higher recurrence rate was recorded in these patients (33.3% vs 14.1%; p = 0.02) as well as a nonsignificant trend to a higher rate of constrictive pericarditis.

Main pulmonary artery aneurysm: a case report and review of the literature.

Main pulmonary artery aneurysms are a rare entity with few available published data. As reported in the literature, operative treatment is commonly recommended but the relation between the size of the aneurysm, its localization, and the risk of rupture is not as well defined as for aortic aneurysms. Proximal lesions that involve the main branches of the pulmonary artery are usually apparent on chest radiographs and must be taken into consideration in the differential diagnosis of mediastinal masses. An early diagnosis allows timely surgical treatment. We report an unusual case of a main pulmonary artery aneurysm presenting with persistent non-productive cough and provide a review of the pertinent published data.

Uncomplicated non-Q wave myocardial infarction: long-term prognosis with a conservative echo-stress guided management strategy.

BACKGROUND: Whether an invasive or a conservative strategy should form the basis of an optimal management strategy for non-Q wave myocardial infarction is at present still subject of debate. We reported our observational experience with the long-term follow-up of patients with a first uncomplicated non-Q wave myocardial infarction and submitted to a conservative treatment strategy based on the in-hospital stress echocardiography and treadmill exercise. METHODS: We studied 134 consecutive patients admitted for a first uncomplicated non-Q wave myocardial infarction between 1991 and 1994. All patients were submitted to a dipyridamole echocardiography test (DET) between 5-7 days after admission and to a treadmill test before discharge. Coronary angiography and myocardial revascularization (coronary angioplasty or coronary artery bypass grafting) were performed according to the outcomes of the stress echo and treadmill test. RESULTS: The early and delayed follow-up results were quite good: 2.9% early hard events, 15% delayed hard events. DET negativity identified patients with a lower risk of both spontaneous and hard events. Multivariate analysis indicated the DET as the only predictive variable of spontaneous events within 1 year (p = 0.0001), of delayed spontaneous events (p = 0.0001) and of delayed hard events (p = 0.05). CONCLUSIONS: In this study, revascularization procedures performed on the basis of stress echo result in good short- and long-term outcomes in stabilized uncomplicated non-Q wave myocardial infarction. The patients with a negative DET had a very low rate of events. DET positivity identifies a higher risk group of patients, whatever treatment they subsequently undergo.
