RESUMO

Heart failure (HF) has high event rates, mortality, and is challenging to manage in clinical practice. Clinical management is complicated by complex therapeutic strategies in a population with a high prevalence of comorbidity and general frailty. In the last four years, an abundance of research has become available to support multidisciplinary management of heart failure from within the hospital through to discharge and primary care as well as supporting diagnosis and comorbidity management. Within the hospital setting, recent evidence supports sacubitril-valsartan combination in frail, deteriorating or de novo patients with LVEF≤40%. Furthermore, new strategies such as SGLT2 inhibitors and vericiguat provide further benefit for patients with decompensating HF. Studies with tafamidis report major clinical benefits specifically for patients with ATTR cardiac amyloidosis, a remaining underdiagnosed and undertreated disease. New evidence for medical interventions supports his bundle pacing to reduce QRS width and improve haemodynamics as well as ICD defibrillation for non-ischemic cardiomyopathy. The Mitraclip reduces hospitalisations and mortality in patients with symptomatic, secondary mitral regurgitation and ablation reduces mortality and hospitalisations in patients with paroxysmal and persistent atrial fibrillation. In end-stage HF, the 2018 French Heart Allocation policy should improve access to heart transplants for stable, ambulatory patients and, mechanical circulatory support should be considered to avoid deteriorating on the waiting list. In the community, new evidence supports that improving discharge education, treatment and patient support improves outcomes. The authors believe that this review fills the gap between the guidelines and clinical practice and provides practical recommendations to improve HF management.

RESUMO

BACKGROUND: Natriuretic peptides have broad indications during heart failure and the detection of left ventricular dysfunction in high-risk patients. They can also be used for the diagnosis/management of other cardiac diseases. However, very little is known regarding their use in routine practice. METHODS: We examined all biological tests performed from February 2010 to August 2015 in two districts from the French Brittany, covering 13,653 km2 and including 22,265 physicians. We report the settings and conditions of N-terminal pro-B-type natriuretic peptide (NT-proBNP) measurements (the only locally natriuretic peptide available). RESULTS: From a total of 3,606,432 tests requested in 557,650 adult (older than 20 years) patients, only 56,653 (1.6%) included at least one NT-proBNP measurement. NT-proBNP measurements gradually increased, from 9188 in 2011 to 12,938 in 2014 (P < 0.001). Most NT-proBNP tests were measured in urban laboratories (72.7%) and in private (62.9%) non-hospital/clinics laboratories; they were mostly ordered by general practitioners (66% compared with 11% by cardiologists). The number of NT-proBNP measurements increased with age up to 80-90 years, and 70.3% of tests were measured in ≥75 years patients. Creatinine and electrolytes were not associated with NT-proBNP in 15.8% and 19.7% of tests, respectively. CONCLUSION: Among a very large cohort, we observed that natriuretic peptides remain largely undermeasured. NT-proBNP is mostly measured in elderly patients, and its interpretation may be hazardous in up to 16% of all individuals because no measurement of creatinine was associated to NT-proBNP.

RESUMO

In asymptomatic patients with type 2 diabetes (T2D), the prevalence of silent myocardial infarction on routine electrocardiograms is about 4% while for silent myocardial ischemia it is 20-30%. Some studies showed that silent myocardial infarction is associated with an increased risk of incident heart failure (HF), whereas no prospective study has ever reported such a risk in patients with silent myocardial ischemia. In patients with HF, however, previously unrecognized coronary artery disease (CAD) often seems to be involved. Brain natriuretic peptide (BNP) and N­terminal pro-BNP (NT-proBNP) levels represent first-line diagnostic tools for patients with suspected HF and might also serve as biomarkers for silent CAD. Echocardiography provides a detailed report of cardiac alterations that includes changes suggestive of ischemia, heart failure, and left ventricular dysfunction in addition to strong prognostic indices. Diabetic patients with silent myocardial infarction or silent myocardial ischemia should be screened for asymptomatic changes in left ventricular function or structure. In patients with silent CAD, all risk factors need to be better controlled and the choice of antihyperglycemic agents adjusted. In patients with congestive HF and no obvious cause of HF, invasive coronary angiography (or noninvasive computed tomography angiography) should be performed to detect CAD, since the finding of CAD may involve revascularization and requires additional treatments including antiplatelet agents and statins. Future research is needed to examine the cost effectiveness of screening for silent myocardial ischemia as part of HF risk assessment, and to identify preventive therapies to lower the risk of HF among patients with silent myocardial infarction.

RESUMO

AIM: To compare combined 2-[18F]-fluoro-2-deoxy-d-glucose (FDG)-positron-emission tomography (PET) and cardiac magnetic resonance imaging (CMR) for the diagnosis and therapy monitoring of cardiac sarcoidosis (CS). MATERIALS AND METHODS: Eighty patients with sarcoidosis and a suspicion of CS who underwent PET and CMR were included retrospectively. PET was undertaken after a low-carbohydrate-high-fat diet in all patients using a combined 16-section PET/computed tomography (CT) camera. PET was considered positive (PET+) in cases of focal or multifocal FDG uptake. CMR was considered positive (CMR+) in cases of subepicardial late gadolinium enhancement (LGE). A subgroup of 50 patients (50/80) was monitored during therapy and classified as responders or non-responders. RESULTS: Eighty-two percent of patients with PET+ (9/11) also had CMR+ imaging, with good spatial agreement (kappa=0,79; 95% confidence interval [CI]: 0.65-0.94). Twenty-seven percent (22/80) had residual physiological FDG uptake, with a standardised uptake value (SUV) not significantly different compared to the SUV from pathological uptake (6.4 versus 6 respectively, p=0,92). The clinical response was more frequent in patients with baseline PET+ compared to baseline PET- (80% versus 45%, p=0.07). PET findings improved in all cases under treatment (7/7), whereas LGE improved in only 33% of patients (3/9). CONCLUSION: Due to high risk of false-positive or undetermined findings, PET might be performed as a second-line study in cases of LGE, to assess inflammatory load. In addition, PET seems suitable to predict and assess response under therapy.

RESUMO

Systemic sclerosis (SSc) is a connective tissue disease characterised by widespread vascular lesions and fibrosis of the skin and internal organs. Cardiac involvement is recognised as a poor prognostic factor when clinically evident. Primary myocardial involvement is common in SSc. Increasing evidence strongly suggests that myocardial involvement is related to repeated focal ischaemia leading to myocardial fibrosis with irreversible lesions. Reproducible data have shown that this relates to microcirculation impairment with abnormal vasoreactivity, with or without associated structural vascular abnormalities. Consistently, atherosclerosis and macrovascular coronary lesions do not seem to be increased in SSc. Myocardial involvement leads to abnormal systolic and diastolic left ventricular dysfunction and right ventricular dysfunction. Sensitive and quantitative methods have demonstrated the ability of vasodilators, including calcium channel blockers and angiotensin converting enzyme inhibitors, to improve both perfusion and function abnormalities further emphasising the critical role of microcirculation impairment. Recent quantitative methods such as tissue Doppler echocardiography and magnetic resonance imaging have underlined these results.

RESUMO

BACKGROUND: Cardiac complications, such as myocardial disease and arrhythmias, are frequent and may be severe in patients with mitochondrial disease. We sought to determine the prevalence and the prognostic value of cardiac abnormalities in a series of patients carrying the m.8344 A>G mutation. METHODS: We retrospectively collected data concerning a cohort of patients carrying the m.8344A>G mutation. Patients systematically underwent neurologic examination, muscular biopsy, measurement of forced vital capacity, and cardiac evaluation including electrocardiogram, echocardiography, and 24-hour ambulatory electrocardiogram at diagnosis. Neurologic and cardiac evaluations were repeated during follow-up at least every 2 years. RESULTS: Eighteen patients (mean age 39.3 +/- 17.3 years, 10 women) from 8 families were investigated. Mean follow-up duration was 5.0 +/- 2.7 years. Cardiac abnormalities were identified at diagnosis in 8 patients (44.4%, age 39.1 +/- 17.7 years), including dilated cardiomyopathy in 4, Wolff-Parkinson-White syndrome in 3, incomplete left bundle branch block in 1, and ventricular premature beats in 1. Two additional patients developed left ventricular dysfunction during follow-up and 2 patients died due to heart failure. Subgroup analyses identified early age at disease onset as the only factor significantly associated with myocardial dysfunction. CONCLUSIONS: We identified a high prevalence of ventricular dysfunction and Wolff-Parkinson-White syndrome. Myocardial involvement was associated with an increased risk of cardiac death due to heart failure, suggesting that cardiac investigations should be systematically considered in patients carrying the m.8344A>G mutation.

RESUMO

OBJECTIVES: To measure the prevalence of, and factors associated with, left ventricular (LV) dysfunction in systemic sclerosis (SSc). METHODS: The EUSTAR database was first searched. A case-control study of a patient subset was then performed to further identify independent factors associated with LV dysfunction by simple and multiple regression. RESULTS: Of 7073 patients, 383 (5.4%) had an LV ejection fraction (EF) of <55%. By multiple regression analysis, age, sex, diffuse cutaneous disease, disease duration, digital ulcerations, renal and muscle involvement, disease activity score, pulmonary fibrosis and pulmonary arterial hypertension were associated with LV dysfunction. In the second phase, 129 patients with SSc with LVEF <55% were compared with 256 patients with SSc with normal LVEF. Male sex (OR 3.48; 95% CI 1.74 to 6.98), age (OR 1.03; 95% CI 1.01 to 1.06), digital ulcerations (OR 1.91; 95% CI 1.05 to 3.50), myositis (OR 2.88; 95% CI 1.15 to 7.19) and use of calcium channel blockers (OR 0.41; 95% CI 0.22 to 0.74) were independent factors associated with LV dysfunction. CONCLUSION: The prevalence of LV dysfunction in SSc is 5.4%. Age, male gender, digital ulcerations, myositis and lung involvement are independently associated with an increased prevalence of LV dysfunction. Conversely, the use of calcium channel blockers may be protective.

RESUMO

Heart involvement, including primary myocardial involvement, is very common in systemic sclerosis (SSc). When clinically evident, cardiac involvement is recognized to be a very poor prognostic factor. Thus pre-clinical identification is highly encouraged. Echocardiography, including pulsed tissue Doppler echocardiography, is the cornerstone of routine heart assessment as it allows the detection of reduced systolic/ diastolic function, as well as the measurement of pulmonary artery pressure, and the possible detection of valvular or pericardial involvement. Myocardial perfusion may be also assessed by single photon emission computed tomography, and if available, by cardiac magnetic resonance imaging. Since the introduction of routine assay for natriuretic peptides, and their initial application for the diagnosis of acute heart failure, B-type natriuretic peptide assays are now recommended for a wide number of applications and have been introduced as a major tool, in particular in primary care, in worldwide guidelines. Within the context of SSc, recent studies have demonstrated that BNP and NT-proBNP are highly relevant for the diagnosis and the prediction of pulmonary hypertension occurrence. Moreover, NT-proBNP allows the detection of both reduced left ventricular/right ventricular contractility, or pulmonary hypertension, suggesting its potential role as a first line tool in primary care setting for the overall cardiac assessment of SSc in which cardiovascular complications are a burden.

RESUMO

BACKGROUND: Cardiac involvement, a common and often fatal complication of systemic sclerosis (SSc), is currently detected by standard echocardiography enhanced by tissue Doppler echocardiography (TDE). OBJECTIVE: The performance of the biomarker of cardiovascular disease, N-terminal pro-brain natriuretic peptide (NT-proBNP), in the detection of cardiac involvement by SSc was examined. METHODS: A total of 69 consecutive patients with SSc (mean (SD) age 56 (13) years, 56 women) were prospectively studied with standard echocardiography and TDE measurements of longitudinal mitral and tricuspid annular velocities. Plasma NT-proBNP was measured in all patients. RESULTS: Overall, 18 patients had manifestations of cardiac involvement, of whom 7 had depressed left ventricular and 8 depressed right ventricular myocardial contractility, and 8 had elevated systolic pulmonary arterial pressure. Patients with reduced contractility had increased mean (SD) NT-proBNP (704 (878) pg/ml versus 118 (112) pg/ml in patients with normal myocardial contractility, p<0.001). Similarly, NT-proBNP was higher in patients with (607 (758) pg/ml) than in patients without (96 (78) pg/ml) manifestations of overall cardiac involvement (p<0.001). Receiver operating characteristic analysis showed NT-proBNP reliably detected depressed myocardial contractility and overall cardiac involvement (area under the curve 0.905 (95% CI 0.814 to 0.996) and 0.935 (95% CI 0.871 to 0.996), respectively). Considering patients with SSc with normal echocardiography and TDE as controls, and using a 125 pg/ml cut-off concentration, sensitivity and specificity were 92% and 71% in the detection of depressed myocardial contractility, and 94% and 78% for overall cardiac involvement. CONCLUSIONS: NT-proBNP reliably detected the presence of cardiac involvement and appears to be a very useful marker to risk stratify patients presenting with SSc.

RESUMO

Primary myocardial involvement is common in SSc. Increasing evidence strongly suggests that this involvement is related to repeat focal ischaemic injury causing irreversible myocardial fibrosis. Clinically evident cardiac involvement is recognized to be a poor prognostic factor, thus pre-clinical identification is highly encouraged. Echocardiography, if possible coupled to pulsed tissue Doppler, is the cornerstone of heart assessment even if radionuclide ventriculography remains the gold standard for evaluation of ventricular function. Myocardial perfusion may be assessed by single photon emission CT, but cardiac MRI will probably supplant this technique; it, furthermore, offers the possibility to concomitantly determine, ventricular function, myocardial perfusion and tissular parameters (i.e. myocarditis or burden of fibrosis). Conduction system abnormalities are common but not serious, while arrhythmias may be life-threatening, necessitating 24-h ambulatory Holter ECG. Natriuretic peptides have been used mainly when the heart has been involved secondary to pulmonary arterial hypertension, but may also be useful for the identification of early heart dysfunction. Their predictive value should also be investigated when there is primary heart involvement.

RESUMO

BACKGROUND: Since the early reports on the incidence of mechanical complications of acute myocardial infarction (AMI) assessed by echocardiography published in the 1980s, the management of patients with AMI has changed considerably, in particular with the progressive development of early revascularisation. METHODS: The aim of this multicentre study was to assess the incidence of mechanical complications of AMI in the reperfusion era. Nine-hundred and eight consecutive patients were included. Echocardiography was performed on admission and at discharge. Seventy-eight percent of patients were revascularised at the acute phase. RESULTS: The following incidence rates of mechanical complications were observed: mitral regurgitation 28%, secondary to left ventricular (LV) remodelling (43%) or papillary muscle dysfunction (57%); pericardial effusion 6.6%, more frequent after anterior AMI and associated with a lower ejection fraction (EF); LV thrombus 2.4%, mainly after anterior AMI and associated with a lower EF (38+/-10% vs. 48+/-12%; p<0.001); early infarct expansion 4%; septal rupture 0.6%; and acute free wall rupture 0.8%. The following factors were independently associated with the occurrence of mechanical complications by multivariate logistic regression analysis: lack of early revascularisation (OR 3.48, 95%CI 1.36-8.95; p<0.001), LV-EF<50% (OR 1.95, 95%CI 1.42-2.67; p<0.001), Killip class>II (OR 1.91, 95%CI 1.27-2.87; p<0.002) and age > or =70 years (OR 1.42, 95%CI 1.03-1.97; p<0.03). CONCLUSION: This study demonstrates the favourable prognostic influence of early revascularisation as shown by the low incidence of mechanical complications after AMI, and underlines the persistent relationship between the development of these complications and depressed LV function.

RESUMO

OBJECTIVE: To evaluate predictors of pulmonary arterial hypertension (PAH) in a prospective cohort of patients with systemic sclerosis (SSc). METHODS: Routine clinical assessments as well as measurements of the diffusing capacity for carbon monoxide/alveolar volume (DLCO/VA) ratio and N-terminal pro-brain natriuretic peptide (NT-proBNP) level were performed in a prospective cohort of 101 SSc patients who did not have PAH or severe comorbidities. After a planned 36-month followup, we evaluated the predictive value of these parameters for the development of precapillary PAH, as demonstrated by cardiac catheterization, disease progression, and death. Criteria for cardiac catheterization were a systolic pulmonary artery pressure (PAP) of >40 mm Hg on echocardiography, a DLCO value of <50% without pulmonary fibrosis, and unexplained dyspnea. RESULTS: Eight patients developed PAH, 29 had disease progression, and 10 died during a median followup of 29 months. Kaplan-Meier analysis identified the following baseline parameters as being predictors of PAH: DLCO/VA ratio <70% or <60% (P<0.01 for each comparison), elevated plasma NT-proBNP level (>97th percentile of normal; P = 0.005), echocardiographically estimated systolic PAP >40 mm Hg (P=0.08), and erythrocyte sedimentation rate >28 mm/hour (P=0.015). In multivariate analyses, an elevated baseline NT-proBNP level (hazard ratio [HR] 9.97 [95% confidence interval (95% CI) 1.69-62.42]) and a DLCO/VA ratio <60% (HR 36.66 [95% CI 3.45-387.6]) were predictors of the occurrence of PAH during followup. An increased NT-proBNP level together with a decreased DLCO/VA ratio of <70% was highly predictive of the occurrence of PAH during followup (HR 47.20 [95% CI 4.90-450.33]). CONCLUSION: This prospective study identified a decreased DLCO/VA ratio and an increased NT-proBNP as predictors of PAH in SSc. Use of these markers should result in improved PAH risk stratification and allow earlier initiation of therapy.

RESUMO

Becker's muscular dystrophy is an X-linked hereditary disorder characterised by progressive muscle weakness and possible cardiac disease. Cardiac involvement is assumed to be rare in young patients. Early diagnosis could lead to earlier treatment at an infra-clinical stage of the disease. The object of the study was to evaluate systolic and diastolic cardiac function of young patients with Becker's disease by echocardiography and using Doppler tissue imaging. Consecutive patients under 20 years of age with Becker's disease confirmed genetically were included and compared with paired normal subjects. Subendocardial and subepicardial myocardial velocities were obtained by Doppler tissue imaging and the corresponding velocity gradients were measured. Twelve patients were included (17.4 +/- 2.5 years). None of them had disabling muscle disease. No significant difference was observed from normal subjects with respect to: ventricular dimensions, wall thickness, fractional shortening, E/A ratio measured by transmitral Doppler. Nevertheless, patients with Becker's disease had lower systolic and diastolic intra-myocardial velocity gradients: 2.2 +/- 1.1 vs. 4.7 +/- 2.4 s(-1), p = 0.006, and 3.6 +/- 2.0 vs. 5.6 +/- 1.3 s(-1), p = 0.048, respectively, compared with the control group. These results show that myocardial disease is possible in patients with Becker's muscular dystrophy under the age of 20. Myocardial Doppler tissue imaging is a sensitive method for detecting these early abnormalities and should be recommended in the young patients.

RESUMO

The incidence of side effects increases dramatically with age. It is estimated that almost one third of side effects could be avoided by an appropriate prescription. On the other hand, age is the main factor associated to the non-prescription of major pharmacological classes, which have evidenced their efficacy in younger patients with coronary artery disease. The estimation of the benefit/risk ratio is therefore highly important in the old/very old patient. It seems important to integrate the results of studies and registries including old patients, evidencing the efficacy of the majority of pharmacological classes validated in younger patients, especially antiplatelets, beta-blockers and statins. The assessment of the benefit/risk ratio should also take into account the tolerance profile of the drug and the patient. The prescription should be adapted to the "age-related" changes of pharmacokinetics and pharmacodynamics.

RESUMO

A 24-year-old woman, with known antiphospholid antibodies (APS), presented with an acute myocardial infarction (AMI) that occurred three months after delivery. No risk factors for arteriosclerosis and no past history of arterial/venous thrombosis were noted. During pregnancy, aspirin prophylaxis was prescribed and followed by steroids after caesarian section. Steroids withdrawal was followed by AMI. Immediate coronary angiography revealed thrombotic occlusion of the left descending coronary artery; PTCA was successfully performed. She was discharged with an antiplatelet and anticoagulant regimen. No recurrent coronary event occurred during follow-up.
