Abstract
Plasma biomarkers have emerged as promising tools for identifying amyloid beta (Aβ) pathology. Before implementation in routine clinical practice, confounding factors modifying their concentration beyond neurodegenerative diseases should be identified. We studied the association of a comprehensive list of demographics, comorbidities, medication and laboratory parameters with plasma p-tau181, glial fibrillary acidic protein (GFAP) and neurofilament light chain (NfL) on a prospective memory clinic cohort and studied their impact on diagnostic accuracy for discriminating CSF/amyloid PET-defined Aβ status. Three hundred sixty patients (mean age 66.5 years, 55% females, 53% Aβ positive) were included. Sex, age and Aβ status-adjusted models showed that only estimated glomerular filtration rate (eGFR, standardized β -0.115 [-0.192 to -0.035], p = 0.005) was associated with p-tau181 levels, although with a much smaller effect than Aβ status (0.685 [0.607-0.763], p < 0.001). Age, sex, body mass index (BMI), Charlson comorbidity index (CCI) and eGFR significantly modified GFAP concentration. Age, blood volume (BV) and eGFR were associated with NfL levels. p-tau181 predicted Aβ status with 87% sensitivity and specificity with no relevant increase in diagnostic performance by adding any of the confounding factors. Using two cut-offs, plasma p-tau181 could have spared 62% of amyloid-PET/CSF testing. Excluding patients with chronic kidney disease did not change the proposed cut-offs nor the diagnostic performance. In conclusion, in a memory clinic cohort, age, sex, eGFR, BMI, BV and CCI slightly modified plasma p-tau181, GFAP and NfL concentrations but their impact on the diagnostic accuracy of plasma biomarkers for Aβ status discrimination was minimal.

Abstract
BACKGROUND Gerstmann-Sträussler-Scheinker (GSS) is a rare prion disease with heterogeneous clinical presentation. Although sleep-related abnormalities are prominent and well-known in other prion diseases such as fatal familial insomnia and Creutzfeldt-Jakob disease, information on sleep is limited in GSS. METHODS We evaluated sleep in three genetically confirmed GSS cases using clinical history, sleep scales and video-polysomnography. In addition, patients underwent neurological assessment, neurological scales, neuropsychological testing, lumbar puncture, brain MRI and brain 18F-FDG-PET. RESULTS Two patients reported sleep maintenance insomnia attributed to leg stiffness and back pain while the remaining patient did not report sleep problems. Video-polysomnography showed normal sleep staging in all of them. Findings such as reduced sleep efficiency in two patients, a confusional arousal in one patient, obstructive apneas in one patient, and periodic legs movements in sleep in two patients were observed. CONCLUSIONS In contrast to fatal familial insomnia, the normal sleep staging in GSS may suggest dissimilar involvement of the neuronal structures that regulate sleep. We found non-specific sleep alterations in GSS such as obstructive apneas and periodic leg movements in sleep which are of unknown origin and of uncertain clinical relevance. Studies including a larger number of patients, serial sleep evaluations and incorporating neuropathological assessment will further help to understand sleep in GSS.

Abstract
BACKGROUND AND OBJECTIVES Blood-based biomarkers have emerged as minimally invasive options for evaluating cognitive impairment. Most studies to date have assessed them in research cohorts, limiting their generalization to everyday clinical practice. We evaluated their diagnostic performance and clinical applicability in a prospective, real-world, memory clinic cohort. METHODS All patients referred with suspected cognitive impairment between July 2019 and June 2021 were prospectively invited to participate. Five plasma biomarkers (tau phosphorylated at threonine 181 [p-tau181], glial fibrillary acidic protein [GFAP], neurofilament light chain [NfL], total tau [t-tau], and ubiquitin C-terminal hydrolase L1 [UCH-L1]) were determined with single-molecule array. Performance was assessed in comparison to clinical diagnosis (blinded to plasma results) and amyloid status (CSF/PET). A group of cognitively unimpaired (CU) controls was also included. RESULTS Three hundred forty-nine participants (mean age 68, SD 8.3 years) and 36 CU controls (mean age 61.7, SD 8.2 years) were included. In the subcohort with available Alzheimer disease (AD) biomarkers (n = 268), plasma p-tau181 and GFAP had a high diagnostic accuracy to differentiate AD from non-neurodegenerative causes (area under the receiver operating characteristic curve 0.94 and 0.92, respectively), with p-tau181 systematically outperforming GFAP. Plasma p-tau181 levels predicted amyloid status (85% sensitivity and specificity) with accurate individual prediction in approximately 60% of the patients. Plasma NfL differentiated frontotemporal dementia (FTD) syndromes from CU (0.90) and non-neurodegenerative causes (0.93), whereas the discriminative capacity with AD and between all neurodegenerative and non-neurodegenerative causes was less accurate. A combination of p-tau181 and NfL identified FTD with 82% sensitivity and 85% specificity and had a negative predictive value for neurodegenerative diagnosis of 86%, ruling out half of the non-neurodegenerative diagnoses. In the subcohort without AD biomarkers, similar results were obtained. T-tau and UCH-L1 did not offer added diagnostic value. DISCUSSION Plasma p-tau181 predicted amyloid status with high accuracy and could have potentially avoided CSF/amyloid PET testing in approximately 60% of subjects in a memory clinic setting. NfL was useful for identifying FTD from non-neurodegenerative causes but behaved worse than p-tau181 in all other comparisons. Combining p-tau181 and NfL improved diagnostic performance for FTD and non-neurodegenerative diagnoses. However, the 14% false-negative results suggest that further improvement is needed before implementation outside memory clinics. CLASSIFICATION OF EVIDENCE This study provides Class I evidence that plasma p-tau181 correlates with the presence or absence of AD and a combination of plasma p-tau181 and NfL correlates moderately well with a diagnosis of FTD.

Abstract
BACKGROUND AND PURPOSE Several diagnostic biomarkers are currently available for clinical use in early-onset cognitive impairment. The decision on which biomarker is used in each patient depends on several factors such as its predictive value or tolerability. METHODS There were a total of 40 subjects with early-onset cognitive complaints (<65 years of age): 26 with Alzheimer's disease (AD), five with frontotemporal dementia and nine with diagnostic suspicion of non-neurodegenerative disorder. Clinical and neuropsychological evaluation, lumbar puncture for cerebrospinal fluid (CSF) AD core biochemical marker determination, medial temporal atrophy evaluation on magnetic resonance imaging, amyloid-positron emission tomography (PET) and 18 F-fluorodeoxyglucose-PET were performed. Neurologists provided pre- and post-biomarker diagnosis, together with diagnostic confidence and clinical/therapeutic management. Patients scored the tolerability of each procedure. RESULTS Cerebrospinal fluid biomarkers and amyloid-PET increased diagnostic confidence in AD (77.4%-86.2% after CSF, 92.4% after amyloid-PET, P < 0.01) and non-neurodegenerative conditions (53.6%-75% after CSF, 95% after amyloid-PET, P < 0.05). Biomarker results led to diagnostic (32.5%) and treatment (32.5%) changes. All tests were well tolerated. CONCLUSIONS Biomarker procedures are well tolerated and have an important diagnostic/therapeutic impact on early-onset cognitive impairment.

Abstract
Background and study aims Colorectal cancer (CRC) risk after a positive fecal immunochemical test (FIT) and negative colonoscopy is unknown. We aimed to ascertain the cumulative incidence of post-colonoscopy colorectal cancer (PCCRC) and the manifestation of other lesions that could explain the test positivity in individuals with a negative colonoscopy in a population screening program. Patients and method Observational study in participants from the first round of a CRC screening program (2010 - 2012) with positive-FIT (≥ 20 μg/g of feces) and negative colonoscopy (without neoplasia). A 42- to 76-month follow-up was performed searching in the National Health Service database and by a brief structured telephonic interview. Results Of 2659 FIT-positive individuals who underwent colonoscopy, 811 (30.5 %) had a negative colonoscopy. Three PCCRC (0.4 %) were detected within 11 - 28 months and accelerated carcinogenesis was ruled out. Among those with normal colonoscopy, 32 (5 %) relevant lesions were detected at follow-up. One-third of them (11/32) were significant neoplasias: a gastric cancer, a small-bowel lymphoma, six advanced colorectal adenomas, and the three PCCRC. The 21 remaining lesions were inflammatory, vascular disorders, or non-advanced colorectal adenomas. Conclusions The vast majority (95 %) of individuals did not present any subsequent lesion that could explain the FIT positivity. The very low incidence (0.4 %) and characteristics of PCCRC observed in our cohort reinforce the concept that, although a positive FIT preselects high risk individuals, a high quality colonoscopy is the paramount factor in preventing PCCRC. Improving quality standards of colonoscopy are required to strengthen the current CRC screening strategies.

Abstract
The variability of total PSA (tPSA) and free PSA (fPSA) results among commercial assays has been suggested to be decreased by calibration to World Health Organization (WHO) reference materials. To characterize the current situation, it is necessary to know its impact in the critical cutoffs used in clinical practice. In the present study, we tested 167 samples with tPSA concentrations of 0 to 20 μg/L using seven PSA and six fPSA commercial assays, including Access, ARCHITECT i2000, ADVIA Centaur XP, IMMULITE 2000, Elecsys, and Lumipulse G1200, in which we only measured tPSA. tPSA and fPSA were measured in Access using the Hybritech and WHO calibrators. Passing-Bablok analysis was performed for PSA, and percentage of fPSA with the Hybritech-calibrated access comparison assay. For tPSA, relative differences were more than 10 % at 0.2 μg/L for ARCHITECT i2000, and at a critical concentration of 3, 4, and 10 μg/L, the relative difference was exceeded by ADVIA Centaur XP and WHO-calibrated Access. For percent fPSA, at a critical concentration of 10 %, the 10 % relative difference limit was exceeded by IMMULITE 2000 assay. At a critical concentration of 20 and 25 %, ADVIA Centaur XP, ARCHITECT i2000, and IMMULITE 2000 assays exceeded the 10 % relative difference limit. We have shown significant discordances between assays included in this study despite advances in standardization conducted in the last years. Further harmonization efforts are required in order to obtain a complete clinical concordance.

Abstract
CEA, CA 125, SCC, CYFRA 21-1 and NSE were prospectively studied in 211 patients with non-small cell lung cancer and compared with clinical parameters (age, sex, Karnofsky Index, symptoms and smoking status), histopathological parameters (stage, histology, tumor size and nodal involvement), biological parameters (LDH and albumin) and the therapy used (surgery, chemotherapy or radiotherapy). Tumor marker sensitivity was CYFRA 21-1: 76%, CA 125: 55%, CEA: 52%, SCC: 33% and NSE: 22%. One of the tumor markers was abnormally high in 87% of the patients with locoregional disease and in 100% of the patients with metastases. Except for NSE, all tumor markers showed a clear relationship with tumor stage and histology and therefore enabled a better histological diagnosis. Abnormal CEA serum levels were mainly found in adenocarcinomas, CA 125 in large-cell lung cancers (LCLC) and adenocarcinomas and SCC in squamous tumors. Eighty-five percent of the patients with SCC levels >2 ng/ml had squamous tumors. Likewise, CA 125 levels <60 U/ml or CEA <10 ng/ml excluded adenocarcinoma or LCLC with a probability of 82 and 91%, respectively.

Abstract
OBJECTIVES The mechanisms of cardiac allograft vasculopathy and its predisposing factors are multifactorial and as yet not well established. To determine the influence of endothelial dysfunction on the development of intimal thickening, we prospectively analyzed the vasomotor response to acetylcholine and nitroglycerin, as well as other donor and recipient variables. Findings were correlated with the coronary intimal thickness, which was evaluated by means of intravascular ultrasonography. METHODS Nineteen patients who had undergone heart transplantation 4.89 +/- 2.35 years previously and who had angiographically normal coronary arteries were included. Endothelial function was analyzed by quantitative coronary analysis of the vasomotor response of the left anterior descending artery to acetylcholine. An intimal thickness index, reflecting the percentage of intima obstructing the coronary lumen, was calculated. RESULTS Nine (47%) patients showed endothelial dysfunction, and the remaining 10 (53%) patients had a normal response. Four (44%) of 9 patients with a weight gain of greater than 20% after the operation showed endothelial dysfunction compared with none of the 10 patients with normal responses (P <.04). The severity of the intimal thickness correlated with the years after transplant (r = 0.45, P <.05). Patients with endothelial dysfunction had more intimal thickening than those without (32% +/- 17% vs 17% +/- 12%, respectively; P <.05). Furthermore, the degree of intimal thickening correlated with the magnitude of the vasomotor response to acetylcholine (r = -0.60, P =.006). No relationship was found between intimal thickness and the vasodilatory response to nitroglycerin. As independent variables for intimal thickness, multivariate analysis detected the magnitude of the response to acetylcholine (P =.0005), years after transplant (P =.01), and ischemic time (P =.03). CONCLUSIONS Cardiac allograft vasculopathy is a multifactorial disease the severity of which increases over time. Endothelial dysfunction is a predictive factor of intimal thickening severity. Predisposing factors that provoke endothelial injury, such as perioperative ischemic time and obesity, may contribute to the development of allograft vasculopathy.

Abstract
The results of the Registry of the Working Group on Hemodynamics and Interventional Cardiology of the Spanish Society of Cardiology for 2000 are presented. Date came from 100 centers representing all the cardiac catheterization laboratories in Spain; 93 centers performed mainly adult catheterization and 7 carried out only pediatric procedures. In 2000, 88,339 diagnostic catheterization procedures were performed (73,382 coronary angiograms), representing a total increase of 12.5% over 1999. The population-adjusted rate was 1,825 coronary angiograms per 106 inhabitants. With a total of 26,993 procedures and a rate of coronary interventions per 106 inhabitants of 671, coronary intervention increased by 17% over figures for 1999. Coronary stents were the devices used most often, with 29,504 implanted in 2000; stenting accounted for 77.2% of procedures, a 30.5% increase over 1999. The increase in direct stenting without predilatation was noteworthy. Direct stenting was done in 8,778 procedures (38.9% of the total), an increase of 131% compared to 1999. IIb-IIIa glycoprotein were used in 4,700 coronary interventions (17%). Angioplasty, performed in 3,128 cases of acute myocardial infarction, accounted for 11.6% of coronary interventions 33.5% more than in 1999. A decrease of 6.5% in valvuloplastics occurred, attributable to the performance of fewer mitral valve repairs (493 vs 525 in 2000 and 1999, respectively). Pediatric procedures increased by 20.5%, from 678 to 817 cases. In conclusion, we would like to underline the high rate of reporting by laboratories, through which the Registry has been able to compile data that are highly representative of the hemodynamic activity in Spain.

Abstract
INTRODUCTION AND OBJECTIVES To present the initial Spanish experience with the Tenax coronary stent, a laser sculpted from high-precision 316L stainless steel coated with hydrogen rich amorphous silicon carbide that reduces thrombogenecity and improves biocompatibility. PATIENTS AND METHODS From July 1998 to July 1999, 206 patients (62 +/- 5 years) underwent implantation of 231 Tenax stents in 9 centers as the only revascularization procedure. The most frequent clinical indication was unstable angina (66%), and most of the lesions were complex (class B2 and C). The target vessels were the left anterior descending (51%) and right coronary arteries (36%). The ejection fraction was < 0.5 in 19% cases. RESULTS Revascularization was complete in 70%, elective in 80%, and the implantation was direct in 25% of the cases. The procedure was successful in all the lesions, reducing stenosis from 62 +/- 16 to 16 +/- 10% and increasing the minimal luminal diameter from 0.81 +/- 0.40 to 2.61 +/- 0.59 mm. The TIMI flow was reduced in 30%, but normalized after the stent in all but one case. The incidence of cardiac events was minimal: 1 acute thrombosis (0.5%) resolved by a new angioplasty and 1 non-Q myocardial infarction (0.5%). At the 6-month clinical follow-up 10% of the patients presented complaints of angina greater than class II, and a new angioplasty was carried out in 1.9% of these cases. CONCLUSION Clinical and angiographic data suggest that the hydrogenated silicon carbide coating of the Tenax coronary stent may indeed play a beneficial role in patient outcome, and should therefore be evaluated by prospective clinical trials.

Abstract
A female with mitral valvular disease presented an acute myocardial infarction. She suddenly complained of recurrent chest pain with symptoms of pulmonary edema. The angiogram evidenced multiple coronary thromboemboli. A combined strategy using intracoronary thrombolysis, a platelet glycoprotein IIb/IIIa antagonist (abciximab) and percutaneous transluminal coronary angioplasty to help disrupt the thrombus was performed. Clinical and angiographic signs of coronary reperfusion were rapidly achieved. No bleeding complications appeared.

Abstract
The cutting balloon is a new device for coronary angioplasty, which, by the combination of incision and dilatation of the plaque, is believed to minimize arterial wall trauma, the neoproliferative response, and subsequent restenosis. In this study, we sought to determine predictors of the restenosis using this technique. Seventy-seven patients underwent successful coronary angioplasty with cutting balloon alone. In 67 of these patients (87%), we performed a control angiogram at 6-month follow-up. Pre-, post-, and late angiographic results were evaluated by quantitative coronary analysis. Clinical and angiographic variables were correlated with restenosis as a binary variable and a continuous variable (late loss and late minimum luminal diameter). Univariate analysis showed that the immediate postprocedure minimum luminal diameter (MLD) was smaller in the restenotic group (defined as MLD > 50% by quantitative coronary angiography) than in the nonrestenotic group (1.90 +/- 0.47 mm vs. 2.19 +/- 0.56 mm, P < 0.05). In addition, the immediate percentage of stenosis was higher in the restenotic group than in the nonrestenotic group (37% +/- 10% vs. 27% +/- 11%, P < 0. 003). Multivariate analysis identified the immediate postcutting balloon percentage of stenosis as an independent determinant of binary restenosis (P < 0.008). When restenosis was defined as a continuous variable, the immediate postprocedure MLD was an independent predictor of late loss (P < 0.02) and of late MLD (P < 0. 0002). No clinical, preprocedure angiographic, or technical variables tested were associated with restenosis. The degree of postprocedural residual stenosis after cutting balloon angioplasty is predictive of late restenosis.

Abstract
A patient with an angiographically unrecognized minor coronary dissection in a stent-covered coronary segment in which a type D spiral dissection extended submedially to the distal artery is described. This complication occurred 6 months after stent implantation and was ascribed to injury of the stented vessel wall during an intravascular ultrasound study.

Abstract
Myocardial bridging of the epicardic coronary arteries is not an uncommon finding in angiographic or necropsic studies. Patients who have symptoms usually improve with medical treatment. However, in refractory patients a surgical myotomy of overlying myocardium and/or a coronary bypass may be needed. We report two patients with long myocardial bridges in the mid-left anterior descending coronary artery, who had recurrent angina refractory to conventional treatment. In both patients two consecutive coronary stents were successfully implanted. At five and six months follow-up they are asymptomatic and with good exercise tolerance.

Abstract
We studied 2 groups of patients with (n = 14) and without (n = 42) minor coronary dissections following cutting balloon angioplasty. Patients with a minor dissection had a longer length of lesion, higher percentage of stenosis, and greater acute gain after angioplasty; at 6-month follow-up both groups had a similar net gain and restenosis rate, suggesting that minor dissection after cutting balloon angioplasty has no influence on restenosis.

Abstract
INTRODUCTION AND OBJECTIVES The Multi-Link intracoronary stent is a balloon-expandable stainless steel stent with an interconnected ring structure designed to provide a high degree of compressive resistance while preserving longitudinal flexibility. We present the results of our initial experience with the implantation of this stent. PATIENTS AND METHODS From May 1996 to April 1997, 124 Multi-link stents were implanted in 97 patients. Mean age 62.2 +/- 11 years. All patients included had a coronary artery diameter > 2.7 mm. Clinical presentation includes stable angina in 20, unstable angina in 72, and myocardial infarction in 5 patients. According to the ACC/AHA classification 6 lesions were type A, 72 type B and 19 type C. The implantation of the stent was for "de novo" lesions in 85 patients and for restenosis in 12. Patients were treated after the procedure with a combination of aspirin and ticlopidine, except six of them who received aspirin and acenocumarol. 16 patients were treated additionally with Abciximab. The degree of stenosis was determined by quantitative angiography. RESULTS The delivery of the stent was successful in all patients. The degree of stenosis before the procedure was 79.6 +/- 13.1%, and after the stent deployment was 17.7 +/- 11.4%. Three patients presented a non-Q-wave myocardial infarction, two patients had a subacute stent thrombosis, one of them died due to heart failure. During a follow-up of 4.7 +/- 2.6 months five patients were readmitted with recurrent angina (4 due to restenosis and one for vessel occlusion) and one patient with heart failure after myocardial infarction died suddenly three weeks after the dilatation. CONCLUSIONS The Multi-Link stent was implanted successfully in all patients with a low incidence of complications, showing at the follow-up a reduced rate of clinical restenosis.

Abstract
OBJECTIVES We sought to determine the prevalence, intensity and evolving changes of myocardial damage detected by myocardial uptake of antimyosin antibodies in patients with alcohol-induced dilated cardiomyopathy, alcohol addicts attending a detoxification unit and healthy subjects with short-term alcohol consumption. BACKGROUND Evidence of alcohol-induced myocardial damage may be provided by myocardial uptake of indium-111-labeled monoclonal antimyosin antibodies. The spectrum of such damage in patients who are heavy drinkers (> 100 g for > 10 years), with or without cardiomyopathy, and the impact of short-term alcohol ingestion on antimyosin antibody uptake have not been adequately explored. METHODS One hundred twenty antimyosin studies were performed in 56 patients with dilated cardiomyopathy (group I), 15 alcohol addicts attending a detoxification unit (group II) and 6 volunteers for short-term alcohol ingestion (group III). Estimation of antibody uptake was calculated through a heart/lung ratio (HLR) (normal < 1.55). RESULTS The 56 patients in group I (54 men, 2 women; mean [+/-SD] age 46 +/- 11 years) had consumed 123 +/- 60 g/day of alcohol for 21 +/- 9 years, for a cumulative intake of 914 +/- 478 kg. Mean duration of symptoms was 46 +/- 49 months. Mean left ventricular end-diastolic diameter was 71 +/- 10 mm, and mean ejection fraction was 28 +/- 12%. No differences in New York Heart Association functional class, ventricular size or ejection fraction were noted between 28 active and 28 past consumers, except for the prevalence and intensity of antibody uptake (75% vs. 32%, p < 0.001) and HLR (1.75 +/- 0.26 vs. 1.49 +/- 0.17, p = 0.0001). In 19 patients in the active group restudied after alcohol withdrawal, antibody uptake decreased (from 1.76 +/- 0.17 to 1.55 +/- 0.19, p < 0.001), and ejection fraction improved (from 30 +/- 12% to 43 +/- 16%, (p < 0.001). No changes occurred in the 15 past consumers restudied. The 15 male patients in group II (mean age 36 +/- 4 years) had consumed 156 +/- 59 g/day for 17 +/- 5 years, for a cumulative alcohol intake of 978 +/- 537 kg, an amount similar to that in patients in group I, but antimyosin antibody uptake was detected in only 3 (20%) of 15 patients. None of six group III subjects developed antibody uptake after short-term ethanol ingestion. Despite the small sample size, the power to detect clinically relevant differences in most variables that did not reach statistical significance was amply sufficient. CONCLUSIONS In alcohol-induced dilated cardiomyopathy, alcohol withdrawal is associated with the reduction or disappearance of myocardial damage and improvement of function. The difference in prevalence of antimyosin antibody uptake in patients with and without cardiac disease who consume similar amounts of alcohol suggests the presence of those with different myocardial susceptibilities to alcohol. Short-term ethanol ingestion in healthy subjects does not induce detectable uptake of antimyosin antibodies.

Abstract
The present report describes three patients with iatrogenic left main coronary artery after aortic valve replacement. All three patients were successfully treated by percutaneous transluminal coronary angioplasty. No clinical or angiographic signs of restenosis were seen during the long-term follow-up (4, 6, and 11 years). These patients show the feasibility of percutaneous transluminal coronary angioplasty in iatrogenic left main coronary artery stenosis as alternative of coronary artery bypass surgery. However, it should be only considered in patients who would otherwise be deemed inoperable, refused reoperation, and are willing to take the risk involved.

Abstract
OBJECTIVES This study aimed to compare indium-111 (111In)-monoclonal antimyosin antibody uptake in patients with dilated cardiomyopathy before heart transplantation with the histologic findings in the explanted hearts. BACKGROUND A high prevalence of 111In-monoclonal antimyosin antibody uptake has been described in patients with dilated cardiomyopathy, suggesting the presence of active, ongoing myocyte damage; however, no correlation between monoclonal antimyosin antibodies and histologic findings is available in these patients. METHODS A consecutive series of 21 patients with dilated cardiomyopathy awaiting heart transplantation were studied with monoclonal antimyosin antibodies before the operation, and the results were compared with the histologic analysis of the explanted hearts. The interval between monoclonal antimyosin antibody studies and transplantation was 1 to 90 days (mean 58 +/- 31). RESULTS Using a semiquantitative method (heart/lung ratio), monoclonal antimyosin antibody uptake was present in 15 (71%) of 21 patients, but active myocarditis in the explanted hearts was detected in only 7. In 11 patients, intense monoclonal antimyosin antibody uptake coexisting with absent myocyte damage or cellular infiltration of explanted hearts was noted. One patient who showed preoperative monoclonal antimyosin antibody uptake underwent transplantation 11 h later, and ex vivo diffuse myocardial antimyosin uptake was detected, but active myocarditis was seen only at cardiectomy in only a small area of the heart; the rest of the myocardium showed no signs of myocyte damage. CONCLUSIONS In dilated cardiomyopathy, monoclonal antimyosin antibody uptake cannot be equated with the presence of an inflammatory response detected in the myocardium of the explanted heart.

Abstract
A 46-year-old female, who underwent an orthotopic heart transplantation 5 years ago, presented an occlusive coronary artery disease with severe stenosis of the left anterior descending artery and a large septal perforator. An isonitrile scintigraphy showed a decreased uptake involving the anterior and inferior segments of the left ventricle. Percutaneous transluminal coronary angioplasty was successfully performed in both lesions. Three months after dilatation, improvement of the uptake in both myocardial segments was detected. The results of the percutaneous transluminal coronary angioplasty published in the literature are reviewed.

Abstract
Dysfunction of a prosthesis implanted in tricuspid position is a severe complication that may develop with minimal symptoms. A patient who presented clinical manifestations of heart failure for two weeks due to obstruction of a mechanical prosthesis in tricuspid position is described. Fibrinolytic treatment was given unsuccessfully, therefore prosthetic replacement was performed. In the removed prosthesis, a fibrotic pannus which developed in the strut and disc was seen. We review the clinical manifestations, the diagnosis and treatment of the dysfunction of a prosthesis implanted in tricuspid position.

Abstract
Haemodynamics and plasma catecholamine responses to isometric exercise were evaluated invasively in 11 orthotopic heart transplant recipients and seven control subjects. Differences in haemodynamic responses between the two groups were already apparent after one min of handgrip at 30% of maximal voluntary contraction, and very pronounced at the end of the fourth minute. At this point transplanted patients showed smaller increments in heart rate (4.8 +/- 3.2 vs 20.4 +/- 14.1 beats.min-1, P less than 0.001), mean arterial pressure (13.7 +/- 7.2 vs 31.5 +/- 12.2 mmHg, P less than 0.001) and cardiac index (0.51 +/- 0.22 vs 1.02 +/- 0.53 L.min-1.m-2, P less than 0.01), whereas left ventricular end-diastolic pressure increased to a greater extent (8.8 +/- 4.9 vs 2.2 +/- 1.8 mmHg, P less than 0.01). Stroke volume index increased similarly (3.8 +/- 1.8 vs 2.0 +/- 3.5 ml beat-1.m-2, NS) and systemic vascular resistance remained unchanged in both groups. The slopes of the left ventricular function curves (ratio of change in left ventricular work to change in left ventricular end-diastolic pressure) indicated depressed left ventricular function in the transplanted patients. The two groups showed similar increments in mixed venous plasma norepinephrine and epinephrine indicating normal sympathoadrenal activation in the transplanted patients. In conclusion, transplanted hearts respond to handgrip with attenuated increases in heart rate, cardiac output and arterial pressure and by increasing left ventricular filling pressure, suggesting a poor contractile reserve probably due to denervation. Circulating catecholamines, especially epinephrine, probably contribute to the cardiac responses to isometric exercise.

Abstract
A 32-year-old man with Hodgkin's disease presented an acute myocardial infarction following mediastinal irradiation. A complete occlusion at the level of the proximal segment of the right coronary artery and a moderate stenosis of the left circumflex coronary artery was demonstrated by selective coronary angiography. An inferior hypokinesia was seen by the ventricular angiography. We discuss the possible role of the mediastinal irradiation in the induction of coronary heart disease as well as the importance of an early diagnosis.

Abstract
Ninety-six coronary angiographies of 30 orthotopic heart transplant recipients were studied. Eleven coronary artery fistulas to right ventricle were seen in 7 (23.3%) patients; five involved the left anterior descending artery, four the right coronary artery, and two the circumflex artery. All the coronary arterial fistulas appeared within the first year after transplantation, when endomyocardial biopsies were more frequent. In the review of the histologic samples, we found coronary arterioles greater than 0.15 mm of diameter in 3 of 7 patients with coronary arterial fistula; on the contrary, those were not found in any of the 69 histologic samples of 23 heart transplant patients without coronary fistula (p less than 0.001). Neither clinic nor hemodynamic abnormalities were seen in any patient during the follow-up. The coronary fistula had a benign course, with a tendency to decrease in size and to close spontaneously.

The long-term clinical course and results of biopsies in 21 patients studied with monoclonal antimyosin antibodies more than 12 months after heart transplantation according to the presence and degree of antimyosin-antibody uptake is described. Eighteen men and three women aged 20-52 years (39 +/- 9 years) were studied with antimyosin antibodies 12-40 months (mean, 22 +/- 9 months) after heart transplantation, and followed for a mean of 18 months (10-28 months). The number of biopsies performed during follow-up was 102. Results showed normal antimyosin-antibody studies in nine patients and abnormal studies in 12 patients. Myocyte damage was identified in 18 of the 102 biopsies (17.6%), one in the normal antimyosin-antibody group of patients and 17 in those patients with myocardial antimyosin-antibody uptake. Patients who developed rejection comprised 11% and 67% of each respective group; the mean number of rejection episodes per patient was 0.11 +/- 0.33 and 1.41 +/- 1.41, respectively (p less than 0.01). A trend was noted by which higher heart-to-lung ratios were associated with greater probability of rejection. Conclusively, 1) antimyosin-antibody studies performed after more than 1 year after heart transplantation indicate the presence and level of rejection activity, 2) groups of patients at risk for developing rejection at biopsy during long-term follow-up may be detected by antimyosin-antibody study, and 3) surveillance for rejection and the degree of immunosuppression should be tailored to meet individual patient needs.

Abstract
A patient with a single coronary artery originating in the right coronary sinus is presented. The condition was diagnosed during aortic valve replacement surgery and later confirmed by coronary angiogram. The clinic significance in relation to the anomalous course of the coronary artery and the importance of correct diagnosis prior to cardiac surgery is discussed.

Abstract
The first 67 consecutive patients (77 lesions) who underwent successful coronary angioplasty (PTCA) at our hospital were clinically followed with serial exercise testing over a 5-year (4 to 7) observation period. Two sequential angiographic controls were performed 6.9 +/- 4.6 (64 patients) and 49.5 +/- 21.6 (42 patients) months after PTCA. The 5-year risk of cardiac death was 8%, of myocardial infarction 2%, or coronary artery bypass grafting 16% and of repeat PTCA 8%. At 5 years, 67% of the patients remain asymptomatic. Restenosis greater than or equal to 70% diameter was observed within the first year after PTCA in 30% of the patients. Progression of coronary artery disease (CAD) was observed in 13 patients (20%). In the first angiographic control, CAD progression was 4% (3/77) in dilated and 3% (3/115) in non-dilated arteries (ns). In the second angiographic control, it was 7% (3/45) and 10% (8/81), respectively (ns). Thus good clinical and angiographic results are still observed after 5 years. Restenosis is an early, self-limited, time-restricted phenomenon that occurs in 30% of patients. Angioplasty does not appear to accelerate CAD progression.

Abstract
Four patients who underwent heart transplantation, in whom coronary obstruction was seen early after transplantation, are described. Repeated acute rejection episodes were detected within the first 2 months in each patient. Coronary obstruction or ischemia was shown through a combination of T1-201 isotopic study findings, evidence of vasculitis of a small coronary arteriole seen at endomyocardial biopsy, or coronary angiographic results. Vigorous treatment for rejection (antithymocyte globulin and bolus methylprednisolone) was given, and coronary artery lesions or myocardial ischemia resolved after treatment. Rejection-induced coronary obstruction should be considered in patients with repeated acute rejection episodes who are predisposed to the development of vascular rejection. Early after transplantation such obstruction is caused by diffuse vasculitis of small and medium-sized vessels and may be reversed with increased immunosuppression.

Abstract
A randomized, double-blind, placebo-controlled trial was performed in 209 patients to evaluate the efficacy of a low dose of aspirin plus dipyridamole or that of a new antiplatelet agent (triflusal) plus dipyridamole in the prevention of aortocoronary vein-graft occlusion. An angiographic control performed in 161 patients 9 days after surgery showed no significant differences between groups, but a new control on 138 of those patients 6 months later did show significant linear trends towards fewer distal anastomosis occlusions (P = 0.027) from the placebo (24%, 22/91) to the aspirin (16%, 17/106) and to the trifusal groups (12%, 10/86), and towards fewer new occlusions (P = 0.056) from 12% (9/78) to 10% (10/99) and to 2.6% (2/78), respectively, in the same groups. A multivariate logistic regression model, used to determine the effect of 33 variables on distal anastomosis occlusion at 6 months control, demonstrated that diameter of distal bed (P = 0.006), moderately to severely atherosclerotic distal bed (P = 0.003) and the interactions between poor distal bed and triflusal (P = 0.005) were independent predictors of occlusion. Thus, triflusal plus dipyridamole appeared superior to low-dose aspirin plus dipyridamole in the prevention of vein-graft occlusion, independently of coronary and vein-graft determinants of occlusion.

Abstract
To establish the accuracy of Doppler echocardiography in the assessment of chronic aortic regurgitation (AR), 87 patients were included in a two-step prospective study. In a first consecutive series of 56 patients, two-dimensional directed M-mode echocardiography and pulsed wave Doppler (PWD) studies were performed within a 24-hour interval of a conventional contrast aortic angiography, which showed AR in 46 patients. Sensitivity and specificity of PWD in the detection of AR were both 100%. To quantitate AR, a left ventricular outflow tract (LVOT) PWD mapping was scored. Significant differences between 1, 2, and 3 to 4 angiographic grades of AR were obtained. As some overlap existed between groups, a multifactorial analysis of PWD and echocardiographic measurements was performed: optimal discrimination was obtained when a new score combining LVOT mapping by PWD, diastolic left ventricular diameter, and aortic root dimension was considered. A prospective validation of this combined echocardiographic-Doppler method was then applied on a second group of 31 catheterized patients with AR. Correlation obtained (r = 0.86; p less than 0.001) confirmed the accuracy of this new method in the prediction of the severity of AR.

Abstract
A study on the value of pulsed Doppler in the detection and quantitative assessment of tricuspid regurgitation (TR) has been conducted on 33 consecutive adult patients with valvular heart disease. Only 1 patient had to be excluded owing to a technically inadequate Doppler examination. Data for comparison were obtained from a right heart catheterization performed within a twenty-four-hour interval from the Doppler study. Sensitivity and specificity in the detection of the lesion were 88% and 100%, respectively. A previously undescribed pulsed Doppler method for the estimation of the degree of TR was tested, based on the consideration of two distinctive patterns of the regurgitant Doppler signal: type I: a protosystolic regurgitant signal with progressively fading intensity along systole; and type II: a homogeneously intense pansystolic signal. Correlation between these patterns and the angiographic degrees of TR showed that milder lesions correspond to the type I Doppler pattern, whereas significant regurgitations present a type II pattern, this allowing a clinically useful method of assessment of TR.

Abstract
Between May 1983 and April 1986, 318 patients underwent cardiac valve replacement with the Monostrut Björk-Shiley prosthesis. There were 136 aortic valve replacements, 128 mitral valve replacements, and 54 multiple replacements. A total of 373 valves were implanted. Associated procedures were done in 79 (25%) of the patients. Hospital (30-day) mortality rate was 5.6% (18 patients): 2.9% (n = 4) after aortic, 7.8% (n = 10) after mitrals and 7.4% (n = 4) after multiple valve replacement. Follow-up was obtained in all 300 operative survivors, for a total of 500 patient-years (mean 18 months). Actuarial survival rate, excluding operative deaths, at 4 years was 94.7% +/- 1.5% (mean +/- standard error of the mean). There were 16 thromboembolic episodes (3.2/100 patient-years). Freedom from all valve-related complications was 87% +/- 2.4% at 3 1/2 years. Neither valve thrombosis nor structural failure has been observed. Eighty percent of the patients are in New York Heart Association functional class I. Forty-two patients (26 with aortic and 16 with mitral valve replacement) underwent cardiac catheterization a mean of 6 1/2 months after the operation. In the aortic position, peak gradients were an average of 6.9 +/- 1.2 mm Hg. Mean systolic gradients were 12.4 +/- 6.3 mm Hg and did not increase with exercise. In the mitral position, end-diastolic gradients were an average of 2.1 +/- 2 mm Hg and mean gradients, 5.9 +/- 2 mm Hg. Discharge coefficient (estimated orifice area/geometric area) was 0.63 +/- 0.2 for the aortic and 0.53 +/- 0.2 for the mitral prostheses. Disc opening was maximal in most patients. These results indicate that the Monostrut prosthesis has a low rate of thromboembolic events, no structural failures or thrombotic obstructions and excellent hemodynamic performance, especially in the small aortic sizes (discharge coefficient for 19 and 21 mm valves, 0.77).
