RESUMO
Importance: Approximately one-third of patients considered for coronary revascularization have diabetes, which is a major determinant of clinical outcomes, often influencing the choice of the revascularization strategy. The usefulness of fractional flow reserve (FFR) to guide treatment in this population is understudied and has been questioned. Objective: To evaluate the usefulness and rate of major adverse cardiovascular events (MACE) of integrating FFR in management decisions for patients with diabetes who undergo coronary angiography. Design, Setting, and Participants: This cross-sectional study used data from the PRIME-FFR study derived from the merger of the POST-IT study (Portuguese Study on the Evaluation of FFR-Guided Treatment of Coronary Disease [March 2012-November 2013]) and R3F study (French Study of FFR Integrated Multicenter Registries Implementation of FFR in Routine Practice [October 2008-June 2010]), 2 prospective multicenter registries that shared a common design. A population of all-comers for whom angiography disclosed ambiguous lesions was analyzed for rates, patterns, and outcomes associated with management reclassification, including revascularization deferral, in patients with vs without diabetes. Data analysis was performed from June to August 2018. Main Outcomes and Measures: Death from any cause, myocardial infarction, or unplanned revascularization (MACE) at 1 year. Results: Among 1983 patients (1503 [77%] male; mean [SD] age, 65 [10] years), 701 had diabetes, and FFR was performed for 1.4 lesions per patient (58.2% of lesions in the left anterior descending artery; mean [SD] stenosis, 56% [11%]; mean [SD] FFR, 0.81 [0.01]). Reclassification by FFR was high and similar in patients with and without diabetes (41.2% vs 37.5%, P = .13), but reclassification from medical treatment to revascularization was more frequent in the former (142 of 342 [41.5%] vs 230 of 730 [31.5%], P = .001). There was no statistical difference between the 1-year rates of MACE in reclassified (9.7%) and nonreclassified patients (12.0%) (P = .37). Among patients with diabetes, FFR-based deferral identified patients with a lower risk of MACE at 12 months (25 of 296 [8.4%]) compared with those undergoing revascularization (47 of 257 [13.1%]) (P = .04), and the rate was of the same magnitude of the observed rate among deferred patients without diabetes (7.9%, P = .87). Status of insulin treatment had no association with outcomes. Patients (6.6% of the population) in whom FFR was disregarded had the highest MACE rates regardless of diabetes status. Conclusions and Relevance: Routine integration of FFR for the management of coronary artery disease in patients with diabetes may be associated with a high rate of treatment reclassification. Management strategies guided by FFR, including revascularization deferral, may be useful for patients with diabetes.

BACKGROUND: Fractional flow reserve (FFR) is not firmly established as a guide to treatment in patients with acute coronary syndromes (ACS). Primary goals were to evaluate the impact of integrating FFR on management decisions and on clinical outcome of patients with ACS undergoing coronary angiography, as compared with patients with stable coronary artery disease. METHODS AND RESULTS: R3F (French FFR Registry) and POST-IT (Portuguese Study on the Evaluation of FFR-Guided Treatment of Coronary Disease), sharing a common design, were pooled as PRIME-FFR (Insights From the POST-IT and R3F Integrated Multicenter Registries - Implementation of FFR in Routine Practice). Investigators prospectively defined management strategy based on angiography before performing FFR. Final decision after FFR and 1-year clinical outcome were recorded. From 1983 patients, in whom FFR was prospectively used to guide treatment, 533 sustained ACS (excluding acute ST-segment-elevation myocardial infarction). In ACS, FFR was performed in 1.4 lesions per patient, mostly in left anterior descending (58%), with a mean percent stenosis of 58±12% and a mean FFR of 0.82±0.09. In patients with ACS, reclassification by FFR was high and similar to those with non-ACS (38% versus 39%; P=NS). The pattern of reclassification was different, however, with less patients with ACS reclassified from revascularization to medical treatment compared with those with non-ACS (P=0.01). In ACS, 1-year outcome of patients reclassified based on FFR (FFR against angiography) was as good as that of nonreclassified patients (FFR concordant with angiography), with no difference in major cardiovascular event (8.0% versus 11.6%; P=0.20) or symptoms (92.3% versus 94.8% angina free; P=0.25). Moreover, FFR-based deferral to medical treatment was as safe in patients with ACS as in patients with non-ACS (major cardiovascular event, 8.0% versus 8.5%; P=0.83; revascularization, 3.8% versus 5.9%; P=0.24; and freedom from angina, 93.6% versus 90.2%; P=0.35). These findings were confirmed in ACS explored at the culprit lesion. In patients (6%) in whom the information derived from FFR was disregarded, a dire outcome was observed. CONCLUSIONS: Routine integration of FFR into the decision-making process of ACS patients with obstructive coronary artery disease is associated with a high reclassification rate of treatment (38%). A management strategy guided by FFR, divergent from that suggested by angiography, including revascularization deferral, is safe in ACS.

BACKGROUND: Penetration of fractional flow reserve (FFR) in clinical practice varies extensively, and the applicability of results from randomized trials is understudied. We describe the extent to which the information gained from routine FFR affects patient management strategy and clinical outcome. METHODS AND RESULTS: Nonselected patients undergoing coronary angiography, in which at least 1 lesion was interrogated by FFR, were prospectively enrolled in a multicenter registry. FFR-driven change in management strategy (medical therapy, revascularization, or additional stress imaging) was assessed per-lesion and per-patient, and the agreement between final and initial strategies was recorded. Cardiovascular death, myocardial infarction, or unplanned revascularization (MACE) at 1 year was recorded. A total of 1293 lesions were evaluated in 918 patients (mean FFR, 0.81±0.1). Management plan changed in 406 patients (44.2%) and 584 lesions (45.2%). One-year MACE was 6.9%; patients in whom all lesions were deferred had a lower MACE rate (5.3%) than those with at least 1 lesion revascularized (7.3%) or left untreated despite FFR≤0.80 (13.6%; log-rank P=0.014). At the lesion level, deferral of those with an FFR≤0.80 was associated with a 3.1-fold increase in the hazard of cardiovascular death/myocardial infarction/target lesion revascularization (P=0.012). Independent predictors of target lesion revascularization in the deferred lesions were proximal location of the lesion, B2/C type and FFR. CONCLUSIONS: Routine FFR assessment of coronary lesions safely changes management strategy in almost half of the cases. Also, it accurately identifies patients and lesions with a low likelihood of events, in which revascularization can be safely deferred, as opposed to those at high risk when ischemic lesions are left untreated, thus confirming results from randomized trials.

INTRODUCTION AND OBJECTIVES: The aim of the present paper is to report trends in Portuguese interventional cardiology from 2004 to 2013 and to compare them with other European countries. METHODS: Based on the Portuguese National Registry of Interventional Cardiology and on official data from the Directorate-General of Health, we give an overview of developments in coronary interventions from 2004 to 2013. RESULTS: In 2013, 36 810 diagnostic catheterization procedures were performed, representing an increase of 34% compared to 2007 and a rate of 3529 coronary angiograms per million population. Coronary interventions increased by 65% in the decade from 2004 to 2013, with a total of 13 897 procedures and a rate of 1333 coronary interventions per million population in 2013. Primary percutaneous coronary intervention (PCI) increased by 265% from 2004 to 2013 (1328 vs. 3524), an adjusted rate of 338 primary PCIs per million, representing 25% of total angioplasties. Stents were the most frequently used devices, drug-eluting stents being used in 73% in 2013. Radial access increased from 4.1% in 2004 to 57.9% in 2013. CONCLUSION: Interventional cardiology in Portugal has been expanding since 2004. We would emphasize the fact that in 2013 all Portuguese interventional cardiology centers were participating in the National Registry of Interventional Cardiology, as well as the growth in primary PCI and increased use of radial access.

Acute heart failure in patients with severe aortic stenosis and left ventricular systolic dysfunction is well known for its dire prognosis and limited therapeutic options. The authors describe the case of a man admitted for non-ST-elevation myocardial infarction. Diagnostic exams revealed severe aortic stenosis, with good left ventricular systolic function, and two-vessel coronary artery disease. The development of cardiogenic shock with left ventricular systolic dysfunction on day four led to changes in the therapeutic strategy. Percutaneous aortic balloon valvuloplasty coupled with complete myocardial revascularization was performed with a view to future surgical intervention. After discharge, the patient was readmitted with acute pulmonary edema, cardiogenic shock and cardiopulmonary arrest. Ventilator weaning was not possible due to acute heart failure and so it was decided to administer levosimendan, which resulted in substantial clinical and echocardiographic improvement. The patient subsequently underwent successful aortic valve replacement. This case highlights the challenge that characterizes the management of patients with concomitant coronary artery disease, left ventricular systolic dysfunction and severe aortic stenosis. Percutaneous aortic balloon valvuloplasty and levosimendan were safe and effective in the treatment of acute heart failure, acting as a bridge to surgery.

A 76-year-old female patient was referred to our institution because of typical chest pain. A continuous murmur was audible at the lower sternal border. A transthoracic echocardiogram showed non-dilated right and left ventricles with mild left ventricular inferior wall hypokinesia and an exercise stress test was positive for myocardial ischemia. A coronary angiogram showed no signs of atherosclerotic coronary artery disease, but it revealed a voluminous fistula between the proximal segment of the right coronary artery and a branch of the pulmonary artery, which was percutaneously closed using 3 embolization coils. Such late presentation of a voluminous coronary fistula is extremely rare and, to the best of our knowledge, very few case reports like this have been published.

INTRODUCTION: There is disagreement regarding the best method for assessing renal dysfunction in patients with myocardial infarction (MI). This study aims to compare two commonly used formulas for measuring glomerular filtration rate (GFR) (Cockcroft-Gault [CG] and modification of diet in renal disease [MDRD]) in terms of predicting extent of coronary artery disease (CAD) and short- and long-term cardiovascular risk. METHODS: We studied 452 patients admitted to a cardiac intensive care unit (ICU) with MI (age 69.01±13.64 years; 61.7% male, 38.5% diabetic) and followed for two years. CG and MDRD GFR estimates were compared in terms of prediction of CAD extent, in-hospital mortality risk and cardiovascular risk during follow-up. RESULTS: GFR <60ml/min/1.73 m(2) using the MDRD formula was associated with a tendency for more extensive CAD (2.70 affected segments vs. 2.20, p=0.052) and higher two-year mortality risk (p<0.001, OR 3.84, 95% CI 2.04-7.22) and risk for reinfarction (p<0.001, OR 4.09, 95% CI 2.00-8.39), decompensated heart failure (DHF) (p<0.001, OR 3.95, 95% CI 2.04-7.66) and combined cardiovascular endpoints (p=0.001, OR 2.47, 95% CI 1.47-4.17). Using the CG formula, GFR<60ml/min/1.73 m(2) only predicted higher risk for DHF (p=0.016, OR 4.5, 95% CI 1.11-16.57), despite a tendency for more overall combined cardiovascular endpoints (p=0.09, OR 2.84). Both formulas predicted in-hospital mortality. DISCUSSION/CONCLUSIONS: This study confirmed the value of GFR in predicting various cardiovascular endpoints in patients with MI. Compared to the CG formula, the MDRD formula was significantly more accurate in predicting the severity of CAD and two-year CV risk in patients admitted to the ICU with MI.

INTRODUCTION: Device closure of interatrial communications has become a well-established technique to treat left-to-right shunt associated with atrial septal defect (ASD) and to prevent paradoxical embolism in patients with patent foramen ovate (PFO). Guidance by transesophageal echocardiography (TEE) is the standard practice but intracardiac echocardiography (ICE) is a feasible and safe alternative for monitoring these procedures. OBJECTIVES: To report our experience in the percutaneous closure of ASD and PFO guided by ICE. METHODS: We retrospectively reviewed all patients with ASD or PFO who underwent percutaneous closure guided exclusively by ICE between January 2008 and December 2010. All patients were followed clinically with regular echocardiographic evaluation (at discharge, one month, three, six and twelve months) to exclude residual shunt and device malposition. RESULTS: A total of 127 patients (mean age 46.6 +/- 12.2 years; 71% female) underwent transcatheter device closure of ASD or PFO during the study period. Device deployment with ICE monitoring was 100% successful, with a low rate of complications and eliminating the need for additional imaging techniques. CONCLUSIONS: ICE provides anatomical detail of ASD/PFO and cardiac structures, facilitating congenital cardiac interventional procedures. It eliminates the major drawbacks associated with TEE and enables the interventional cardiologist to control all aspects of the procedure without relying on additional echocardiographic support.

AIMS: Ischemic Mitral Regurgitation (MR) has early prognostic impact in Myocardial Infarction (MI). Its medium-term importance, especially of mild MR, has not been established. PURPOSE: to determine new clinical/analytical predictors of MR in MI-patients and establish its prognostic value during two-year follow-up [endpoints: mortality, decompensated heart failure (dHF)]. METHODS AND RESULTS: 796 patients admitted for MI (age 68.8±13.4, 63.2% males, 44.6% STEMI). DATA: Admission analytical study, risk scores, coronariography, pre-discharge echocardiogram. Patients followed for two years. Clinical/analytical predictors of pre-discharge MR assessed. Predictive model for presence of pre-discharge MR included GRACE for intra-hospital mortality [IHM](OR=1.008, p<0.001), glomerular filtration rate (GFR)[OR=0.993, p=0.048], admission haemoglobin (OR=0.84, p=0.003). In univariate analysis, moderate-severe MR predicted 2-year mortality (OR=3.32, p<0.001), but not dHF. Two year mortality rate was proportional to severity of pre-discharge MR. Mild MR (vs. no MR) associated with higher risk for 2-year mortality (OR=2.04, p=0.014) and re-admission for dHF (OR=2.55, p=0.001). Predictive model for 2-year mortality included MR severity (OR=1.42, p=0.033) and GRACE for IHM (OR=1.023, p<0.001). CONCLUSION: GRACE score for IHM, GFR and admission haemoglobin independently predicted risk for pre-discharge MR. MR, including its milder form, was an independent predictor of 2-year mortality, adding prognostic power to GRACE score.

INTRODUCTION: Percutaneous coronary intervention (PCI) of heavily calcified lesions is a challenge for the interventional cardiologist and is associated with a high rate of restenosis and target lesion revascularization (TLR). Adequate lesion preparation by rotational atherectomy followed by drug-eluting stent implantation has shown favorable results. OBJECTIVE: To report the recent experience of our center with rotational atherectomy (RA) of complex and heavily calcified coronary lesions. METHODS: We retrospectively analyzed consecutive patients who underwent PCI with RA in our center between January 2009 and December 2010. A total of 42 patients were included, 65% of whom had been previously refused for coronary artery bypass grafting due to unfavorable coronary anatomy or high surgical risk. RA was performed using the standard Boston Scientific Rotablator(®) system. The procedure was performed ad-hoc in 50% of patients and transradial access was used in 35%. Data were collected on immediate post-procedural events and major cardiac events during follow-up - cardiovascular death, myocardial infarction, TLR and recurrent angina. RESULTS: Of 1650 PCIs performed in a 23-month period from January 2009, 42 (2.5%) involved RA, a total of 42 patients (mean age 70.3±10.1 years, 67% male, 55% diabetic), three of whom had left main disease, six had three-vessel disease, 18 had two-vessel disease and the other 15 had single-vessel disease. Of the lesions treated, 71% were >20 mm long and classified in 69% of cases as type C according to the ACC/AHA lesion classification, 4% being chronic total occlusions. The left anterior descending artery was treated in 56% of the procedures. The mean number of burrs used per lesion was 1.3 and a total of 69 stents were implanted, 81% of which were drug-eluting. During follow-up three patients had recurrent angina, one required TLR and two died due to a cardiovascular event. There was significant clinical improvement in 83% of patients. CONCLUSIONS: This study demonstrates that rotational atherectomy followed by stenting in heavily calcified lesions can nowadays be performed with high success rates and few complications, extending the possibility of coronary revascularization to a greater number of patients.

INTRODUCTION: Patients with coronary artery disease (CAD) are at increased risk of stroke. The aim of this study was to analyze the prognostic accuracy of selected clinical and laboratory variables in stroke risk prediction following discharge after myocardial infarction (MI). METHODS: We analyzed 404 consecutive patients (aged 68.1±13.7 years; 63.4% male; 37.4% with diabetes) without previous stroke who were discharged in sinus rhythm after being admitted for MI. The following data were collected: cardiovascular risk factors, admission blood glucose (BG), HbA1c, creatinine, peak troponin levels; glomerular filtration rate (GFR) by the MDRD formula; maximum Killip class; GRACE score for in-hospital and 6-month mortality; and extent of CAD. Patients were followed for two years and each variable was tested as a possible predictor of cerebrovascular events (stroke or transient ischemic attack [TIA]). RESULTS: During follow-up, 27 patients were admitted for stroke or TIA. The presence of diabetes, hypertension, dyslipidemia and previously known CAD, type of MI (STEMI vs NSTEMI) and extent of CAD did not predict cerebrovascular risk. The following variables were associated with higher stroke risk: GFR <60ml/min/m(2) (p=0.029, OR 2.65, 95% CI 1.07-6.55); maximum Killip class >1 (p=0.025, OR 2.71, 95% CI 1.10-6.69); GRACE in-hospital mortality >180 (p=0.001, OR 4.09, 95% CI 1.64-10.22); admission BG >140 mg/dl (p=0.001, OR 5.74, 95% CI 1.87-17.58); GRACE 6-month mortality >150 (p=0.001, OR 4.50, 95% CI 1.80-6.27); and peak troponin >42ng/ml (p=0.032, OR 2.64, 95% CI 1.06-6.59). Logistic regression analysis produced a model with the predictors GRACE 6-month mortality >150 (OR 3.26; p=0.014) and admission BG >7.7mmol/l (OR 4.09; p=0.017) that fitted the data well (Hosmer-Lemeshow: p=0.916). DISCUSSION/CONCLUSIONS: In patients with MI, variables known to be predictors of in-hospital mortality, including admission BG, renal function, acute heart failure and GRACE score, were found to be useful predictors of stroke during 2-year follow-up. While both GRACE score for 6-month mortality >150 and admission BG >7.7 mmol/l were independent predictors of stroke, CV risk factors, previously known CAD, and extent of CAD assessed by coronary angiography did not improve stroke risk prediction. This study highlights the need for even more aggressive secondary prevention in patients most at risk.

BACKGROUND: Fast and effective diagnosis of patients with acute myocardial infarction (AMI) in the Emergency Department (ED) is needed. Manchester Triage (MT) is based on identification of the patient's main complaint, establishing, through decision flowcharts, a target-time for first observation. This study aimed to evaluate the impact of MT on short-term mortality in AMI and detect potential improvements, and to analyse high-risk groups: diabetic patients, women and older patients. METHODS: 332 consecutive patients (69.0+13.6 years mean age; 34.9% women) with final diagnosis of AMI were assessed in the ED using MT. Data were analysed according to demographics and risk groups, as well as several AMI parameters, admission duration and intrahospital mortality (IHM). Independent predictors of mortality were determined. RESULTS: 82.8% of patients met the ideal goal of ≤10 min target-time for a first observation (ITTFO). This was higher (95%) in typical presentations ('chest pain'), versus 52% in other flowcharts; p<0.01. Patients ≥70 years old were less frequently screened with ITTFO ≤10 min (76.2% vs 90.0% in those under 70; p=0.001) or the 'chest pain' flowchart (66.9% vs 77.5%; p=0.031). IHM was 13.3%. Triage with ≤10 min ITTFO and the 'chest pain' algorithm seems to predict a lower mortality (0.33 OR; 95% CI 0.17 to 0.63; p=0.0005 and 0.49 OR; 95% CI 0.24 to 1.03; p=0.056). CONCLUSION: MT proved to be an effective system. Patients with typical AMI presentation, ST elevation myocardial infarction and less than 70 years old are protected by MT, with lower ITTFO and better short-term survival.

INTRODUCTION: Sudden cardiac death (SCD) is one of the most common causes of death in the young. It may be preceded by "red flags", but screening for these warning signs is not routinely performed. OBJECTIVE: To test a new questionnaire for fast clinical assessment of possible warning signs of serious heart disease in a young population. METHODS: We studied a population of 1472 university students and hospital employees (mean age 22.3 +/- 5.9 years; maximum age 40 years; 56.5% women), using a rapid-response questionnaire, evaluating major cardiac symptoms, past pathological and family history and medication: the Sudden Cardiac Death-Screening of Risk Factors (SCD-SOS) questionnaire. Descriptive statistical analysis and comparison of quantitative and nominal variables were performed using SPSS version 16.0. RESULTS: Of the questionnaires, 0.3% were blank and 3.5% had 1 to 3 missing answers (of a total of 8); 42.5% had no previous cardiac complaints, 27.8% had previous syncope and 24.5% chest pain; palpitations were reported by 23.5%, cardiac murmur by 5.9%, epilepsy or antiepileptic drugs by 1.6%, cardiovascular medication by 1.4% and family history of cardiac disease by 3.3%. A history of sudden unexplained or cardiovascular death in first- or second-degree family members was reported by 2.0%. Full analysis of the questionnaires identified 69 participants (4.7%) with at least one warning sign indicating need for cardiological evaluation, among whom 17 had two warning signs and three had three. CONCLUSIONS: SCD-SOS detected some cases requiring careful examination by a cardiologist. It could, however, be improved in some respects (characterization of chest pain, palpitations and family history of heart disease), in order to clearly identify possible high-risk patients. Applying this questionnaire together with an ECG may be a better way of risk stratifying this population.

A ocorrência de Hemopericárdio com Tamponamento Cardíaco é uma complicação da Valvoplastia Mitral Percutânea por balão (VMB), que apesar de pouco freqüente, pode ter graves conseqüências materno-fetais. Este artigo descreve o caso de um tamponamento cardíaco após VMB em uma mulher de 28 anos, com estenose mitral reumática severa na 20ª semana de gravidez.
The occurrence of hemopericardium with cardiac tamponade is a complication of percutaneous balloon mitral valvuloplasty (BMV) which, although uncommon, may have severe maternal and fetal consequences. This article describes a case of cardiac tamponade following BMV in a 28-year-old woman with severe rheumatic mitral stenosis in the 20th week of gestation.

The purpose of this study is to evaluate morphologic patterns of ostium secundum-type atrial septal defects (osASD) in the adult, analyzing their role in treatment decisions. The population was composed of 155 adults (age 43.3 +/- 18.9 years) consecutively diagnosed with osASD in our center, and confirmed by transthoracic and transesophageal echocardiography, between January 2000 and December 2007. Of these, 83 (53.5%) underwent successful percutaneous closure. Surgical closure was used in 31 patients (20.0%). The remaining 42 patients (27.1%) received conservative medical treatment. The mean diameter of the defects was 15.8 +/- 8.5 mm. The prevalence of mitral valve prolapse and severe pulmonary hypertension was also assessed. Based on the criteria in the literature, we detected 14 different morphologic patterns of osASD. There was a central defect in 45/155; 40/155 had a short rim and 20/155 two short rims, 24/155 were multifenestrated and 15/155 PFO-like, and 12/155 had three or more short rims. The different morphologic patterns in each treatment arm, as well as the criteria leading to their inclusion in each, are described. While percutaneously closed defects had a simpler morphology, those that were surgically closed were normally larger and had a more complex shape (with two or more deficient rims or multifenestrated, and thus not suitable for percutaneous closure).
