Abstract

Objective: Self-perceived health status may be helpful in identifying patients at high risk for adverse outcomes. The Euro Heart Survey on Coronary Revascularization (EHS-CR) provided an opportunity to explore whether impaired health status was a predictor of 1-year mortality in patients with coronary artery disease (CAD) undergoing angiographic procedures. Methods: Data from the EHS-CR that included 5619 patients from 31 member countries of the European Society of Cardiology were used. Inclusion criteria for the current study were completion of a self-report measure of health status, the EuroQol Questionnaire (EQ-5D) at discharge and information on 1-year follow-up, resulting in a study population of 3786 patients. Results: The 1-year mortality was 3.2% (n = 120). Survivors reported fewer problems on the five dimensions of the EQ-5D as compared with non-survivors. A broad range of potential confounders were adjusted for, which reached a p

Abstract

Aims: Revascularization in patients with coronary artery disease changed over the last two decades, favouring the number of patients treated by means of percutaneous coronary interventions (PCI) when compared with coronary artery bypass grafting (CABG). Many randomized controlled trials (RCTs) have been performed to compare these two competing revascularization techniques. Because of the strict enrolment criteria of RCTs in which highly selected patients are recruited, the applicability of the results may be limited in clinical practice. The current study evaluates to what extent patients in clinical practice were similar to those who participated in RCTs comparing PCI with CABG. Methods and results: Clinical characteristics and 1-year outcome of 4713 patients enrolled in the Euro Heart Survey on Coronary Revascularization were compared with 8647 patients who participated in 14 major RCTs, comparing PCI with CABG. In addition, we analysed which proportion of survey patients would have disqualified for trial participation (n = 3033, 64%), aiming at identifying differences between trial-eligible and trial-ineligible survey patients. In general, important differences were observed between trial participants and survey patients. Patients in clinical practice were older, more often had comorbid conditions, single-vessel disease, and left main stem stenosis when compared with trial participants. Almost identical differences were observed between trial-eligible and trial-ineligible survey patients. In clinical practice, PCI was the treatment of choice, even in patients who were trial-ineligible (46% PCI, 26% CABG, 28% medical). PCI remained the preferred treatment option in patients with multi-vessel disease (57% in trial-eligible and 40% in trial-ineligible patients, respectively, P < 0.001); yet, the risk profile of patients treated by PCI was better than that for patients treated either by CABG or by medical therapy. In the RCTs, there was no mortality difference between PCI and CABG. In clinical practice, however, we observed 1-year unadjusted survival benefit for PCI vs. CABG (2.9 vs. 5.4%, P < 0.001). Survival benefit was only observed in trial-ineligible patients (3.3 vs. 6.2%, P < 0.001). Conclusion: Many patients in clinical practice were not represented in RCTs. Moreover, only 36% of these patients were considered eligible for participating in a trial comparing PCI with CABG. We demonstrated that RCTs included younger patients with a better cardiovascular risk profile when compared with patients in everyday clinical practice. This study highlights the disparity between patients in clinical practice and patients in whom the studies that provide the evidence for treatment guidelines are performed. © The European Society of Cardiology 2006.

Abstract

The purpose of this registry is to collect data on trends in interventional cardiology within Europe. Special interest focuses on relative increases and ratios in newer revascularization approaches and its distribution in different regions in Europe. We report the data of the year 2003 and give an overview of the development of coronary interventions since 1992, when the first data collection was performed. Questionnaires were distributed yearly to delegates of all national societies of cardiology represented in the European Society of Cardiology to collect the case numbers of all local institutions and operators. The overall numbers of coronary angiographies increased from 1992 to 2003 from 684, 000 to 1, 993, 000 (from 1, 250 to 3, 500 per million inhabitants). The respective numbers for percutaneous coronary interventions (PCI-coronary angioplasty) and coronary stenting procedures increased from 184, 000 to 733, 000 (from 335 to 1, 300) and from 3, 000 to 610, 000 (from 5 to 1, 100), respectively. Germany has been the most active country for the past years with 653, 000 angiographies (7, 800), 222, 000 angioplasties (2, 500), and 180, 000 stenting procedures (2, 200) in 2003. The indication has shifted towards acute coronary syndromes, as demonstrated by raising rates of interventions for acute myocardial infarction over the last decade. The procedures are more readily performed and safer, as shown by increasing rate of "ad hoc" PCI and decreasing need for emergency coronary artery bypass surgery (CABG). In 2003, use of drug-eluting stents had further increased. However, an enormous variability is reported with the highest rate in Portugal (55%). Interventional cardiology in Europe is still expanding, mainly but not exclusively due to rapid growth in the eastern European countries. A number of new coronary revascularization procedures introduced over the years have all but disappeared. Only stenting has experienced an exponential growth. The same can be forecast for drug-eluting stenting.

Abstract

Aims: To evaluate clinical disease expression, non-invasive diagnosis, and prognosis in families with dominant vs. recessive arrhythmogenic right ventricular cardiomyopathy (ARVC) due to mutations in related desmosomal proteins plakophilin-2 (PKP2) and plakoglobin (JUP), respectively. Methods and results: One hundred and eighty-seven individuals belonging to ARVC families, four with dominant PKP2 mutations and 12 with recessive JUP mutation underwent serial non-invasive cardiac assessment. Survival and arrhythmic events were evaluated prospectively up to 21 years (median 8.5 years). Sixteen of 22 PKP2 carriers and all 26 homozygous JUP carriers fulfilled the diagnostic criteria for ARVC, the youngest by the age of 13 years. Clinical disease expression did not differ significantly between PKP2 and JUP carriers. T-wave inversion in leads V1-V3, right ventricular wall motion abnormalities, and frequent ventricular extrasystoles were the most sensitive/specific markers for identification of mutation carriers. QRS dispersion ≥40 ms was an independent predictor of syncope but not of sudden death. Conclusion: Mutations in PKP2 and JUP express similar cardiac phenotype. Non-invasive family screening may largely be based on T-wave inversion, right ventricular wall motion abnormalities, and frequent ventricular extrasystoles to identify mutation carriers. © The European Society of Cardiology 2006.

Abstract

Introduction. Longitudinal studies on lone AF are rare and the incidence of hypertension in this population unknown. This study aimed at investigating the incidence of arterial hypertension in patients with apparently lone atrial fibrillation (AF). Methods and Results. Out of 292 consecutive patients presented with permanent or paroxysmal AF, 32 patients were diagnosed as having lone AF according to strict criteria. Three patients were subjected to ablation of the ligament of Marshall, 14 patients to pulmonary vein isolation, and the remainder were treated with beta blockade. Patients were followed-up for a 1-3 year period. During follow-up, 14 patients were diagnosed as having arterial hypertension. Thirteen of them had recurrent AF despite ligament of Marshall ablation (1 patient), pulmonary vein isolation (4 patients) and beta blockade (8 patients). Cox regression analysis revealed that the only significant predictor of development of hypertension was complete or partial response to antiarrhythmic therapy (beta = 3.82, S.E. = 1.22, exp(b) = 45.63, 95% C.I. = 4.17-499.2, p = 0.001), independent of age (beta = -0.01, p = 0.74), sex (beta = -0.91, p = 0.28), left ventricular ejection fraction (beta = 0.06, p = 0.52), left atrial size (beta = 0.58, p = 0.7) and kind of antiarrhythmic therapy (ablation or drug therapy) (beta = 1.36, p = 0.09). In patients with lone AF that did not respond at all to antiarrhythmic therapy, there was a 45.6 times higher risk of diagnosing hypertension during the next 3 years as compared to responders. Conclusion. Approximately 44% of patients with an initial diagnosis of lone AF may represent occult cases of arterial hypertension. In these patients hypertension may affect AF recurrence and treatment outcomes, regardless of the mode of antiarrhythmic therapy used.

Abstract

Patients with beta-thalassaemia major frequently suffer from hypersiderosis which leads to hemochromatosis of major organs such as the heart and liver. Little information exists about the ultrastructural pathology of the human heart in beta-thalassaemia patients. Five Cypriot patients with elevated blood ferritin and intractable heart failure were investigated. Cardiac biopsies from these patients were studied by light and electron microscopy, as well as by X-ray microanalysis. Ultrastructural examination revealed the presence of disrupted myocytes showing loss of myofibers, dense nuclei, and a variable number of pleomorphic electron dense granules. These cytoplasmic granules or siderosomes consisted of iron-containing particles as confirmed by X-ray microanalysis. It is likely that the ultrastructural changes observed in myocytes of patients with beta-thalassaemia are largely due to iron deposition. 24 2 75 81

Abstract

INTRODUCTION: Isolation of all pulmonary veins (PV) is advocated for treatment of paroxysmal atrial fibrillation (PAF). However, the superior PVs are responsible for most AF triggers, whereas the inferior PVs carry the higher risk for ablation-induced ostial stenosis. The aim of this study was to compare a superior PV isolation approach with isolation of all PVs for treatment of PAF. METHODS AND RESULTS: Fifty-two patients with PAF were randomized to either left superior pulmonary vein (LSPV) isolation followed by additional isolation of the right superior pulmonary vein (RSPV) in case of AF recurrence (group A, n = 27) or isolation of all four PVs followed by a repeat procedure in case of recurrence (group B, n = 25). At 1-year follow-up, 11 patients (41%) in group A and 8 patients (32%) in group B had AF relapse (P = 0.55). No significant differences in AF relapse were detected between groups at 3 and 12 months (log rank = 0.36, P = 0.54) and by Cox proportional hazards model analysis (P = 0.62). Nonsignificant PV stenosis was detected in two patients from group B. Total radiofrequency energy delivery and fluoroscopy and procedure times were lower in group A: 8.9 +/- 1.4 minutes vs 25.6 +/- 3.7 minutes (P < 0.001), 22.2 +/- 6.8 minutes vs 62 +/- 10.3 minutes (P < 0.001), and 131.8 +/- 26.5 minutes vs 222.2 +/- 32.3 minutes (P < 0.001), respectively. CONCLUSION: A staged superior PVs isolation approach confers equal success rates but with reduced radiofrequency energy delivery and fluoroscopy and procedure times compared to isolation of all PVs at the initial ablation attempt.

16. Infective endocarditis on stenotic aortic valves.

Author

Delahaye, J. P., Loire, R., Milon, H., De Gevigney, G. Durand, Delahaye, F., Boissonnat, P., Zambartas, C., Etienne, J., and Malquarti, V.

Abstract

Charts were reviewed of 42 adult patients (27 men, 15 women, mean age 55 years, with 17 older than 60) hospitalized and/or autopsied between 1970 and 1986 with diagnosis of definite or highly probable infective endocarditis (IE) on pure aortic stenosis (AS). Ring and/or septal abscesses were found in 18/37 patients who were operated upon and/or autopsied. IE was recognized in 32 patients, undiagnosed in 10 (revealed at autopsy in seven, at operation in three). Infecting organisms were identified in 26 patients (Str. viridans, 16; Str. D, three; Staphylo., four; other, three). Twenty-seven patients were treated in our institution, 14 of them more than four weeks after the beginning of the symptoms. Echocardiograms were recorded in 17, with vegetations in only six. Severe cardiac failure was present in 17 cases. One patient was lost to follow-up. Fourteen patients died (mean delay between IE and death 22·4 months): eight of the 13 non-operated patients (cardiac failure, four; myocardial infarction, two; neurological complications, two) and six of the 14 operated patients (perioperative death, four; late sudden death, two). Twelve patients are alive (mean follow-up 51·6 months), eight of them in NYHA class 1. IE on pure AS is rare, difficult to recognize echocardiographically, and of poor prognosis. It usually requires rapid aortic valve replacement. [ABSTRACT FROM PUBLISHER]

17. The anatomical aspects of adult aortic stenosis.

Author

Normand, J., Loire, R., and Zambartas, C.

Abstract

Since the recent introduction of percutaneous balloon valvuloplasty, there has been a renewed interest in anatomical studies. This study was based on a retrospective analysis of 100 autopsy reports and 269 surgical reports from adult patients with AS. Valvular calcification, which was always found over the age of 50 years, plays an important part in the origin of aortic stenosis (AS). Congenital or acquired aortic valvular lesions are a common pre-condition for calcified AS.Three anatomical types were found: (i) calcified bicuspid valves with anterior and posterior cusps (more frequent than a left and a right cusp) were found in 41% of autopsy reports and 40% of surgical reports. The resultant rigidity due to calcification makes the valve stenotic; (ii) post rheumatic calcified AS with strong fusion of the commissures and calcified cusps was found in 30% of autopsy reports and 8% of surgery reports, and (iii) degenerative calcific aortic stenosis was the most frequent form found over 70 years of age. The sinuses of Valsalva were filled with calcium deposits. The three commissures were apparently free, but cusp fusion was found on the ventricular aspect of the valve (29% of autopsy cases and 52% of surgical reports). Percutaneous balloon valvuloplasty is more efficient in this anatomical type. [ABSTRACT FROM PUBLISHER]

Abstract

In the present study Doppler-echocardiography was used to evaluate the quality of mitral valve regurgitation (MVR) repair by Carpentier valvuloplasty. Between January, 1984 and June, 1987, this operation was performed in 51 patients (39 men, 12 women; mean age 58 +/- 10.9 years) presenting with mitral valve regurgitation; 25 were in class III and 14 in class IV of the NYHA classification. Two patients died soon after the operation and 2 others some time later. The 47 survivors were followed up for a mean period of 20.5 +/- 11.2 months: 3 of them required mitral valve replacement for residual MVR or mitral stenosis, one developed cerebral embolism. At the latest control, 18 patients were in NYHA class I and 26 in NYHA class II. Doppler velocimetry showed no or little mitral valve dysfunction; the residual MVR was below grade 1 in 37 of the 44 survivors who were not reoperated upon. Mitral function was satisfactory after Carpentier valvuloplasty, with a mean transmitral gradient of 3.3 +/- 1.3 mmHg and a mean mitral valve area of 2.9 +/- 0.98 cm2. In 3 patients an intraventricular gradient of 10 to 20 mmHg, reflecting moderate ventricular obstruction, was detected by Doppler velocimetry. These data obtained with the combined Doppler-echocardiographic method confirm that the quality of mitral function is excellent after Carpentier mitral valvuloplasty.

Abstract

The aim of this study was to investigate exercise-induced ST-segment depression in subjects with a 120-ms or shorter PR segment and normal coronary arteries. A population of 86 individuals who demonstrated ST-segment depression of 1.5 mm or more on treadmill testing and had a subsequent normal coronary arteriography was classified into two groups. Group A (n = 71) comprised those with a normal PR interval on baseline electrocardiogram 160.9 +/- 14.8 ms (mean +/- 1 SD), and group B (n = 15) comprised those with a 120-ms or shorter PR interval 113 +/- 8.8 ms (mean +/- 1 SD). All subjects had undergone a symptom-limited treadmill test by the standard Bruce protocol (mainly for evaluation of chest pain or angina-like pain), during which they demonstrated ST depression of 1.5 mm or more in either lead II, lead V2, or lead V5. All had normal or near normal coronary arteries on angiography. In the subjects with short PR segments and angiographically normal coronaries, a trend of greater ST-segment depression during treadmill testing as compared with control subjects was observed in lead V5. In the same group, ST-segment depression at the 9th minute of exercise was more prevalent in lead V5 than in lead II or V2.

Abstract

Members of a family have been investigated because of three sudden deaths among them. Two young sisters, aged 12 and 16, died suddenly while swimming and running, while their 19-year-old brother died suddenly during emotional stress. In no case did autopsies reveal any structural abnormalities. Their 39-year-old mother and her 19-year-old daughter gave a history of syncopes, while having a normal physical examination and normal ECGs. During a treadmill test, multiple ventricular extrasystoles and bursts of polymorphic ventricular tachycardia were provoked. Patient-members of this family have undergone echocardiography, catheterization of the left and right sides of the heart, endomyocardial biopsy, and electrophysiologic studies. A differential diagnosis of an inherited long QT interval syndrome, catecholamine-induced arrhythmias, and arrhythmogenic right ventricular dysplasia have been suggested. Patients were given atenolol and were followed up for 18 months. This therapy has greatly reduced the exertional arrhythmias as assessed by serial treadmill tests.

Abstract

A 61-year-old woman with chronic asthma sustained an episode of dyspnea and chest heaviness and was brought to the emergency department. Her examination revealed tachypnea, tachycardia, hypotension, and diffuse prolonged respiratory wheezing. Arterial blood gas analysis showed severe hypoxemia and hypercapnia. A 12-lead electrocardiogram showed marked, downsloping ST-segment depression, with deep, negative T waves in leads I, II, III, and aVF and precordial leads V3-V6. After 15 minutes of therapy with oxygen, beta-agonists, and corticosteroids, the electrocardiographic abnormalities subsided and 2 hours later they had disappeared. Subsequent coronary angiography and ventriculography revealed normal coronary arteries and good left ventricular ejection fraction. It is concluded that an acute asthmatic paroxysm may produce transient myocardial ischemia even with angiographically documented normal coronary arteries.

Abstract

This paper studies the factors associated with perioperative myocardial infarction after coronary bypass surgery and assesses the medium-term prognosis of these patients. Four hundred and seventy patients underwent coronary bypass surgery between January 1983 and December 1986. The appearance and persistence of pathological Q waves, absent on the preoperative ECG, was the unique criterion of perioperative infarction. This complication was observed in 36 patients (7.65%). A comparison of these patients with a random group of 144 of teh 434 patients without perioperative infarction showed that they had a higher incidence of crescendo angina (55% vs 21%; p less than 0.001), ST-T wave changes on the resting ECG (78% vs 46%; p less than 0.001) and poor distal left anterior descending network (33% vs 13%; p less than 0.001): in addition, the group with infarction had a lower left ventricular ejection fraction (0.58 vs 0.64, p less than 0.01), incomplete myocardial revascularisation procedures (58% vs 32%; p less than 0.01), longer cardiopulmonary bypass times (86 mn vs 69 mn; p less than 0.001) and longer aortic clamping times (44.5 mn vs 37.4 mn p less than 0.05). The acute phase of the perioperative infarct was characterised by a higher incidence of major cardiac complications such as low output states (30.5% vs 2.02%; p less than 0.001). The hospital mortality was higher in the infarct group (8.3% vs 2.01%) but this was not statistically significant. After an average follow-up of 44 +/- 3 months, the 5 year survival rate was 95.4 +/- 2.1 per cent in patients without infarction and 76.5 +/- 6.9 per cent in those with perioperative infarction (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract

An original model for estimating myocardial ischaemia from coronary arteriography is proposed. Four parameters are taken into consideration: anatomical variations, the myocardial mass perfused, the degree of reduction of basal flow across the stenosis, the eventual summation of several successive stenotic lesions. This scoring system was tested by simulation on a computer and evaluated in 100 anginal patients. Analysis of our preliminary results shows statistically significant differences in the score between the following groups of patients: patients with normal and those with abnormal LV wall motion; patients with and those without previous myocardial infarction; patients with Class II stable angina and those with other forms (III, IV and unstable angina).

Abstract

In the present study Doppler-echocardiography was used to evaluate the quality of mitral valve regurgitation (MVR) repair by Carpentier valvuloplasty. Between January, 1984 and June, 1987, this operation was performed in 51 patients (39 men, 12 women; mean age 58 +/- 10.9 years) presenting with mitral valve regurgitation; 25 were in class III and 14 in class IV of the NYHA classification. Two patients died soon after the operation and 2 others some time later. The 47 survivors were followed up for a mean period of 20.5 +/- 11.2 months: 3 of them required mitral valve replacement for residual MVR or mitral stenosis, one developed cerebral embolism. At the latest control, 18 patients were in NYHA class I and 26 in NYHA class II. Doppler velocimetry showed no or little mitral valve dysfunction; the residual MVR was below grade 1 in 37 of the 44 survivors who were not reoperated upon. Mitral function was satisfactory after Carpentier valvuloplasty, with a mean transmitral gradient of 3.3 +/- 1.3 mmHg and a mean mitral valve area of 2.9 +/- 0.98 cm2. In 3 patients an intraventricular gradient of 10 to 20 mmHg, reflecting moderate ventricular obstruction, was detected by Doppler velocimetry. These data obtained with the combined Doppler-echocardiographic method confirm that the quality of mitral function is excellent after Carpentier mitral valvuloplasty.

Abstract

The purpose of this retrospective study of 28 cases of staphylococcal endocarditis on cardiac valve prosthesis was to evaluate the prognosis of that disease and the possible causes of its recent improvement. Between March 1977 and May 1987, 69 patients were treated for bacterial endocarditis on cardiac valve prosthesis. Among these, 28 patients (19 men, 9 women, mean age 53.2 +/- 14.3 years) had staphylococcal endocarditis (Staph. epidermidis in 18 cases, Staph. aureus in 10 cases) of early (10 cases) or late (18 cases) onset. Complications were present in no less than 27 out of 28 patients, the most frequent being heart failure, embolism or neurological disorders. The mortality rate was high (61 p. 100). Among the clinical variables studied, only a state of shock seemed to be predictive of death. Mortality was higher in the group treated medically (100 p. 100) than in the group treated surgically (50 p. 100). Since 1984, however, a significant decrease of mortality was noted; it coincided with the systematic use of vancomycin but also with surgical treatment in all cases. As a result of this study, we suggest that all patients with staphylococcal endocarditis on cardiac valve prosthesis should be operated upon and that this should be done as soon as possible, before the end of the classical antibiotic therapy period.

Abstract

In order to determine the value of a positive exercise test (ET) (i.e. ischaemic ST depression) without chest pain observed after a myocardial infarction (MI), 102 ET's were reviewed. ET was performed without anti-ischaemic drugs. The mean time-lag between MI and ET was 51 +/- 55 months. The MI was inferior in 26 cases, inferior and/or posterior in 74 cases and of undetermined location in 2 cases. Thirty patients had both ST depression and chest pain (group 1); 35 had electrocardiographic signs of ischaemia without pain (group 2), and 37 had neither chest pain nor signs of ischaemia (group 3). Age, sex ratio, site of infarction and time-lag between MI and ET were similar in all three groups. The post-ET follow-up period was 33 +/- 18 months (range: 6 to 66 months); 2 patients in group 3 were lost sight of. There was no significant difference between groups 1 and 2 as regards total duration of ET, workload attained, heart rate, systolic arterial pressure, pressure-rate product and amplitude of ST depression at maximum exercise level. Group 3 differed from the other 2 groups in workload attained (p less than 0.05) and in pressure-rate product (p less than 0.05 vs group 1, p less than 0.01 vs group 2). There was no significant difference between groups 1 and 2 as regards post-ET events (recurrent angina, reinfarction, coronary bypass, transluminal angioplasty).(ABSTRACT TRUNCATED AT 250 WORDS)
