    ABSTRACT: To investigate the relative incidence, clinical presentation and prognosis of myopericarditis among patients with idiopathic or viral acute pericarditis. Prospective observational clinical cohort study. Two general hospitals from an urban area of 220 000 inhabitants. 274 consecutive cases of idiopathic or viral acute pericarditis between January 2001 and June 2005. Relative prevalence of myopericarditis. Clinical features at presentation including echocardiographic data (ejection fraction (EF), wall motion score index (WMSI)) and follow-up data at 12 months including complications, results of echocardiography, electrocardiography and treadmill testing. Myopericarditis was recorded in 40/274 (14.6%) consecutive patients. At presentation, the following clinical features were independently associated with myopericarditis: arrhythmias (odds ratio (OR) = 17.6, 95% confidence interval (CI) 5.7 to 54.1; p<0.001), male gender (OR = 6.4, 95% CI 2.3 to 18.4; p = 0.01), age <40 years (OR = 6.1, 95% CI 2.2 to 16.9; p = 0.01), ST elevation (OR = 5.4, 95% CI 1.4 to 20.5; p = 0.013) and a recent febrile syndrome (OR = 2.8, 95% CI 1.1 to 7.7; p = 0.044). After 12 months' follow-up an increase of EF (basal EF 49.6 (5.1)% vs 12-month EF 59.1 (4.6)%; p<0.001) and decrease of WMSI (basal WMSI 1.19 (0.27) vs 12-month WMSI 1.02 (0.09); p<0.001) were recorded in patients with myopericarditis, with a normalisation of echocardiography, electrocardiography and treadmill testing in 98% of cases. Use of heparin or other anticoagulants (OR = 1.1, 95% CI 0.3 to 3.5; p = 0.918) and myopericarditis (OR = 2.3, 95% CI 0.7 to 7.6; p = 0.187) was not associated with an increased risk of cardiac tamponade or recurrences. Myopericarditis is relatively common and shows a benign evolution also in spontaneous cases not related to vaccination.

    ABSTRACT: Colchicine seems to be well tolerated and effective in the treatment and prevention of pericarditis. A preliminary clinical trial has shown that colchicine may be considered not only for the treatment of postpericardiotomy syndrome (PPS), but also for its primary prevention. The COPPS study is a multicentre, double-blind, randomised trial. On the third postoperative day, 360 patients, 180 in each treatment arm, will be randomised to receive placebo or colchicine (1.0 mg twice daily for the first day followed by a maintenance dose of 0.5 mg twice daily for 1 month in patients > or =70 kg, and halved doses for patients <70 kg or intolerant to the highest dose). The primary efficacy endpoint is the incidence of PPS at 12 months. Secondary endpoints are disease-related hospitalisation, cardiac tamponade, constrictive pericarditis, and relapses at 18 months. Additional analysis will include the time to PPS. The COPPS trial will evaluate the use of colchicine for the primary prevention of PPS. This study will also provide important information on the frequency, clinical presentation, and prognosis of this syndrome in clinical practice.

    ABSTRACT: 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. 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. 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.

    ABSTRACT: 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. 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. 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.

    ABSTRACT: 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. 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. 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. 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.

    ABSTRACT: Fifty-five of 294 consecutive patients with acute pericarditis had first attacks of recurrent pericarditis and were evaluated and treated according to a management protocol. Corticosteroids were restricted to aspirin contraindication or failure. Colchicine was added in cases of aspirin and prednisone failure and was the treatment of choice for the second and subsequent recurrences. After logistic regression multivariate analysis, only the previous use of corticosteroids (odds ratio 10.35, 95% confidence interval 4.46 to 23.99, p <0.001) was associated with an increased risk for recurrence. After a mean follow-up of 72 months (range 48 to 108), a similar rate of complications was found in patients with or without recurrences.

    ABSTRACT: 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.

    ABSTRACT: 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.

    ABSTRACT: 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.

    ABSTRACT: We sought to investigate the safety and efficacy of a protocol for acute pericarditis triage and outpatient management of low-risk cases. Acute pericarditis has generally a brief and benign course after empiric treatment by non-steroidal anti-inflammatory drugs, and routine hospitalization of most patients may be unnecessary. From January 1996 to December 2001, all consecutive cases of acute pericarditis were evaluated on a day-hospital basis. Patients without clinical poor prognostic predictors (fever >38 degrees C, subacute onset, immunodepression, trauma, oral anticoagulant therapy, myopericarditis, severe pericardial effusion, cardiac tamponade) were considered low-risk cases and assigned to outpatient treatment with high-dose oral aspirin. Patients with poor prognostic predictors or aspirin failure were hospitalized for etiology search and treatment. A clinical and echocardiographic follow-up was performed at 48 to 72 h, 7 to 10 days, 1 month, 6 months, and 1 year. Two hundred fifty-four out of 300 (84.7%) patients were selected as low-risk cases. Outpatient treatment was efficacious in 221 out of 254 (87%) cases. Thirty-three out of 254 patients were hospitalized because of aspirin failure. Patients treated on an out-of-hospital basis had no serious complications after a mean follow-up of 38 months (no cases of cardiac tamponade). A higher frequency of recurrences and constriction was recorded in aspirin-resistant cases than in aspirin responders (60.6% vs. 10.4% for recurrences and 9.1% vs. 0.5% for constriction, respectively; all p < 0.01). A protocol for acute pericarditis triage and outpatient therapy of low-risk cases is safe and efficacious and may reduce management costs.

    ABSTRACT: This study was designed to investigate the prognostic value of cardiac troponin I (cTnI) in viral or idiopathic pericarditis. Idiopathic acute pericarditis has been recently reported as a possible cause of nonischemic release of cTnI. The prognostic value of this observation remains unknown. We enrolled 118 consecutive cases (age 49.2 +/- 18.4 years; 61 men) within 24 h of symptoms onset. A highly sensitive enzymoimmunofluorometric method was used to measure cTnI (acute myocardial infarction [AMI] threshold was 1.5 ng/ml). A cTnI rise was detectable in 38 patients (32.2%). The following characteristics were more frequently associated with a positive cTnI test: younger age (p < 0.001), male gender (p = 0.007), ST-segment elevation (p < 0.001), and pericardial effusion (p = 0.007) at presentation. An increase beyond AMI threshold was present in nine cases (7.6%), with an associated creatine kinase-MB elevation, a release pattern similar to AMI, and echocardiographic diffuse or localized abnormal left ventricular wall motion without detectable coronary artery disease. After a mean follow-up of 24 months a similar rate of complications was found in patients with a positive or a negative cTnI test (recurrent pericarditis: 18.4 vs. 18.8%; constrictive pericarditis: 0 vs. 1.3%, for all p = NS; no cases of cardiac tamponade or residual left ventricular dysfunction were detected). In viral or idiopathic acute pericarditis cTnI elevation is frequently observed and commonly associated with young age, male gender, ST-segment elevation, and pericardial effusion at presentation. cTnI increase is roughly related to the extent of myocardial inflammatory involvement and, unlike acute coronary syndromes, is not a negative prognostic marker.

    ABSTRACT: 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. 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. 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). 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.

    ABSTRACT: This report describes a case of an unusual association between vasospastic angina, coronary myocardial bridging, and Brugada syndrome. The patient complained of chest pain followed by rhythmic palpitation and syncope. Brugada syndrome ECG markers were documented with transient ST-segment elevation in lateral leads. A coronary angiogram showed a myocardial bridging in the left anterior descending artery and coronary vasospasm was reproduced after intracoronary ergonovine injection in the circumflex coronary artery. Ventricular fibrillation was induced by programmed electrical stimulation. The described association can be important because interaction between ischemia and Brugada syndrome electrophysiological substrate could modulate individual susceptibility to life-threatening ventricular tachyarrhythmias.

    ABSTRACT: 28-year-old man was admitted to the Emergency De- partment for syncope after several hours of violent vomiting and diarrhea. A few minutes after arrival, he complained of palpitations followed by a sudden loss of consciousness. An ECG showed a polymorphic ventricular tachycardia degenerating into ventricular fibrillation (Figure 1). Because of recurrent major ventricular arrhythmias, re- suscitation was necessary for 1 hour. The patient was even- tually admitted to the Coronary Care Unit. Physical exami- nation, ECG (Figure 2), chest x-ray, echocardiogram, and routine blood chemistry were all normal. A history of a previous suicide attempt with rat poison was discovered, and a small bag of Aconitum napellus (wolfsbane, monkshood) seeds was found in the patient's trousers. After several psychiatric assessments, the patient confessed to ingesting an

    ABSTRACT: Isolated alterations of the left ventricular diastolic function have been described in diabetic insulin-dependent patients (IDDM), even in the absence of old age, hypertension, ischemic heart disease, left ventricular hypertrophy. Such alterations have been associated with microangiopathy but it is not known whether it is reversible or if there is a relation with the way the therapy is given. Fifty-five subjects have been studied, of which 15 were healthy, 30 recently diagnosed IDDM without microangiopathy and 10 IDDM with microangiopathy. All the patients were under 35 years old and did not present risk factors for coronary artery disease, hypertension or autonomic neuropathy. The maximal exercise stress test proved negative. The diastolic function was studied using the results of Doppler echocardiography of the mitral flow and of isovolumetric relaxation time, with continuous and discrete parameters. The velocity of wave A and E, the relationship between them and their integrals are significantly greater in diabetics with microangiopathy than in those without it and in healthy subjects. There are no significant differences between healthy and diabetic subjects without microangiopathy using continuous parameters. Using discrete parameters diastolic damage is absent in the healthy subjects and is present in 48% of diabetics without microangiopathy and in 90% of those with it. Slight preclinical diastolic dysfunction is present in young recently diagnosed IDDM without microangiopathy. More severe dysfunction is present when there is also microangiopathy.

    ABSTRACT: Dynamic 24-hour recordings were obtained in 10 healthy non hospitalized subjects. Spectral analysis of RR interval variabilities provided quantitative markers of sympatho-vagal balance throughout the day and night. The low frequency (0.1 Hz) component was considered a marker of sympathetic activity whereas the high frequency component (0.25 Hz) a marker of vagal tone. We observed an early morning rise in the sympathetic activity markers in all our patients, with a second smaller rise in the early afternoon. We believe this rise may be the trigger of the increased rate of major cardiovascular events reported to happen in the first hours of the morning.
