Abstract
Abstract
Background
In clinical practice, as stated in the ASE guidelines, the echocardiographic estimation of right atrial pressure (RAP) is based on the size of the inferior vena cava (IVC) and its inspiratory collapse. However, this method has proven to have limits of reliability and reproducibility. The use of a recently developed software that with a semi-automatic technique highlight the edges of the IVC could help to standardize the echocardiographic assessment of RAP.
Aim of the study: The aim of the study was to assess feasibility and accuracy of a new semi-automated approach to estimate the RAP.
Standard acquired echocardiographic images were processed with a semi-automatic technique, indexes related to the collapsibility of the vessel during inspiration (Caval Index, CI), during the whole respiratory cycle (Respiratory Caval Index, RCI) and through the heart cycle transmitted movements’ (Cardiac Caval Index (CCI) were derived (figure 1).
Using these indexes, we developed two models:
a) the Binary Tree Model (BTM), further divided in BTM3 and BTM5 (RAP estimated in 3 and 5 classes, respectively);
b) the Regression Model (RM), further divided in RM linear (continuous model) and RM3 and RM5 (RAP estimated in 3 and 5 classes respectively).
RAP assessed using these innovative techniques were compared with two standard estimation (SE) echocardiographic methods A and B.
Direct RAP measurements obtained during a right heart catheterization (RHC), performed within 6 hours, were used as reference.
Results
62 consecutive ‘all-comers’ patients that had a RHC were enrolled; 13 patients were excluded for technical reasons. Therefore 49 patients were included in this study (26 males and 23 females; mean age of 62.2 ± 15.2 years, 75.5% pulmonary hypertension, 34.7% severe left ventricular dysfunction and 51% right ventricular dysfunction). The two SE methods showed poor accuracy for RAP estimation (method A: ME = 51%, R2= 0.22; method B: ME = 69%, R2= 0.26). Instead, the new semi-automatic methods BTM3 and BTM5 based on parameters derived from IVC edge tracking (mean IVC diameter, CI, CCI and RCI) had a misclassification error of only 14% (R2 = 0.47) and 22% (R2 = 0.61), respectively, to classify RAP. The accuracy was lower for RM than BTM (RM3: ME = 61%, R2 = 0.39; RM5: ME = 55%, R2 = 0.39). However, the RM showed the lowest mean bias in estimating RAP: 0.23 [-8.34; 8.81] mmHg.
Conclusions
A multi-parametric approach using the new indexes, such as CCI and RCI, derived from a semi-automated edge tracking of the IVC is a promising tool for a more accurate estimation of RAP. This study proposes an innovative method for the non-invasive estimation of the RAP, which requires confirmation on larger population.

Abstract
OBJECTIVE The objective was to provide an exhaustive characterization of ECG features in a large cohort of dilated cardiomyopathies (DCMs) and then investigate their possible prognostic role in the long term. BACKGROUND ECG is an accessible, reproducible, low-cost diagnostic and prognostic tool. However, an extensive description of ECG features and their long-term prognostic role in a large cohort of DCM is lacking. METHODS All available baseline ECGs of DCM patients enrolled from 1992 to 2013 were systematically analysed. Patients underwent to a complete clinical-laboratory evaluation. The study outcome measures were death or heart transplant (D/HT) and sudden death or malignant ventricular arrhythmias (SD/MVA). RESULTS Four hundred and fourteen DCM patients were enrolled. During a median follow-up of 125 months, 55 and 57 patients experienced D/HT and SD/MVA, respectively. At multivariate analysis, left ventricular hypertrophy (P = 0.017), heart rate (HR, P = 0.005) and anterolateral T-wave inversion (P = 0.041) predicted D/HT. Regarding SD/MVA, S wave amplitude in V2 (P = 0.008), R wave amplitude in DIII (P = 0.007), anterolateral T-wave inversion (P = 0.017) emerged as predictors. At receiver-operating curve analyses, the addition of ECG models to the clinical-laboratory evaluation significantly increased the area under the curve both for D/HT (from 0.68 to 0.74, P = 0.042) and SD/MVA (from 0.70 to 0.77, P = 0.048). CONCLUSION The exhaustive systematic evaluation of ECG has an incremental impact in the prognostication of a large cohort of DCM patients, also regarding the arrhythmic stratification.

Abstract
BACKGROUND Pericardial effusion is frequent in the acute phase of ST-segment elevation myocardial infarction. However, its prognostic role in the era of primary percutaneous coronary intervention is not completely understood. METHODS We investigated the association between pericardial effusion, assessed by transthoracic echocardiography, and survival in a large cohort of ST-segment elevation myocardial infarction patients treated with primary percutaneous coronary intervention, enrolled in the Trieste primary percutaneous coronary intervention registry from January 2007 to March 2017. Multivariable analysis and a propensity score approach were performed. RESULTS A total of 1732 ST-segment elevation myocardial infarction patients were included. Median follow-up was 45 (interquartile range 19-79) months. Pericardial effusion was present in 246 patients (14.2%). Thirty-day all-cause mortality was similar between patients with and without pericardial effusion (7.8% vs. 5.4%, P=0.15), whereas crude long-term survival was worse in patients with pericardial effusion (26.2% vs. 17.7%, P≤0.01). However, at multivariable analyses the presence of pericardial effusion was not associated with long-term mortality (hazard ratio 1.26, 95% confidence interval 0.86-1.82, P=0.22). Matching based on propensity scores confirmed the lack of association between pericardial effusion and both 30-day (hazard ratio 1, 95% confidence interval 0.42-2.36, P=1) and long-term (hazard ratio 1.14, 95% confidence interval 0.74-1.78, P=0.53) all-cause mortality. Patients with pericardial effusion experienced a higher incidence of free wall rupture (2.8% vs. 0.5%, P<0.0001) independently of the entity of pericardial effusion. CONCLUSIONS In acute ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention, the onset of pericardial effusion after ST-segment elevation myocardial infarction is not independently associated with short and long-term higher mortality. Free wall rupture has to be considered rare compared to the fibrinolytic era and occurs more frequently in patients with pericardial effusion, suggesting a close monitoring of these patients in the early post-primary percutaneous coronary intervention phase.

Abstract
Abstract
Background
Genotype-phenotype correlations in dilated cardiomyopathy (DCM) and in particular the effects of gene variants on clinical outcomes remain poorly understood.
Purpose
To investigate the prognostic role of genetic variant carrier status in a large cohort of DCM patients.
Methods
We analyzed 487 DCM patients by next-generation sequencing and categorized the disease genes into functional gene groups. The following composite outcome measures were assessed: 1) all-cause mortality, heart transplantation or left ventricular assist device (D/HTx/VAD); 2) sudden cardiac death or malignant ventricular arrhythmias (SCD/MVAs); 3) heart failure related death, heart transplantation or left ventricular assist device implantation (DHF/HTx/VAD).
Results
A total of 187 pathogenic/likely pathogenic variants were found in 180 patients (37%): 55 (11%) TTN; 19 (4%) LMNA; 24 (5%) structural cytoskeleton-Z disk genes; 16 (3%) desmosomal genes; 47 (10%) sarcomeric genes; 8 (2%) ion channels genes; 11 (2%) other genes. The occurrence of D/HTx/VAD was no different between variant carriers and non-carriers (p=0.17). However, carriers of desmosomal and LMNA variants experienced the highest rate of SCD/MVA, which was independent of the left ventricular ejection fraction.
Conclusions
Desmosomal and LMNA gene variants identify the subset of DCM patients at greatest risk for SCD and life-threatening ventricular arrhythmias, regardless the left ventricular ejection fraction.

Abstract
PURPOSE Patients with symptomatic heart failure (HF), reduced left ventricular ejection fraction (LVEF), and high-grade functional mitral regurgitation (MR) may benefit from percutaneous edge-to-edge mitral valve repair (PMVR). However, patient selection still remains a central issue. We sought to investigate the potential role of the global longitudinal strain- (GLS-) based left ventricular contractile reserve (LVCR) at dobutamine stress echocardiography (DSE) in this setting. METHODS Thirty-three stable HF patients (MR grade ≥ 3+; median LVEF, 29%; median GLS, -8.3%) who were candidates for PMVR were prospectively enrolled. All patients underwent DSE to assess LVCR (LVEF increase ≥ 5%; GLS increase ≥ 2%; stroke volume [SV] increase ≥ 20% of the measured SV value). RESULTS After DSE, a positive LVCRLVEF was detected in 21 patients (64%), positive LVCRGLS in 12 patients (36%), and positive LVCRSV in 14 patients (42%). LVCRGLS was associated with better symptom relief, MR improvement, and LV reverse remodeling in a short-term follow-up. A significant improvement of GLS during DSE (hazard ratio [HR], 0.549; 95% CI, 0.395-0.765; P < .001), along with history of HF hospitalization (HR, 1.48; 95% CI, 1.119-1.967; P = .006) and beta-blocker therapy (HR, 0.146; 95% CI, 0.046-0.462; P = .001), were independently associated with risk of death/heart transplantation/HF-related hospitalizations. CONCLUSIONS LVCR, assessed by speckle-tracking DSE, is associated with better results after PMVR in the setting of advanced HF. Improvement of longitudinal function emerged, beyond the ejection fraction, as an independent predictor of outcomes and could improve the selection of best candidates for the percutaneous correction of functional MR.

Abstract
Background Limited data are available on mid-range ejection fraction (mrEF) patients with dilated cardiomyopathy. We sought to define the characteristics, evolution, and long-term prognosis of dilated cardiomyopathy patients with mrEF at diagnosis. Methods and Results We analyzed all dilated cardiomyopathy patients consecutively evaluated in the Trieste Heart Muscle Disease Registry from 1988 to 2013. mrEF and reduced ejection fraction (rEF) were defined as baseline left ventricular (LV) ejection fraction values between 40% and 49% and <40%, respectively. All-cause mortality or heart transplantation, sudden cardiac death, or major ventricular arrhythmias were considered as outcome measures. Worsening LV ejection fraction (reduction to <40%) during follow-up was also considered to identify possible predictors of adverse remodeling. Among 812 enrolled patients, 175 (22%) presented with mrEF at presentation. At baseline, as compared with the rEF group, mrEF patients had lower rates of moderate-severe mitral regurgitation and restrictive LV filling pattern. During a median follow-up period of 120 (60-204) months, the mrEF group presented a lower rate of death/heart transplantation (9% versus 36%, P<0.001) and sudden cardiac death or major ventricular arrhythmias (4.5% versus 15%, P<0.001) than rEF patients. Moreover, 29 out of 175 mrEF patients (17%) evolved to rEF. Restrictive LV filling pattern emerged as the strongest predictor of rEF development following multivariable analysis. Conclusions mrEF identified a consistent subgroup of dilated cardiomyopathy patients diagnosed in an earlier stage with subsequent apparent better long-term evolution. However, 17% of these patients evolved into rEF despite the use of medical therapy. A baseline restrictive LV filling pattern was independently associated with subsequent evolution to rEF.

Abstract
Early marginal bone loss (MBL) is a non-infective remodeling process of variable entity occurring within the first year after implant placement. It has a multifactorial etiology, being influenced by both surgical and prosthetic factors. Their impact remains a matter of debate, and controversial information is available, particularly regarding implants placed subcrestally. The present multicenter prospective clinical study aimed to correlate marginal bone loss around platform-switched implants with conical connection inserted subcrestally to general and local factors. Fifty-five patients were enrolled according to strict inclusion/exclusion criteria by four clinical centers. Single or multiple implants (AnyRidge, MegaGen, South Korea) were inserted in the posterior mandible with a one-stage protocol. Impressions were taken after two months of healing (T1), screwed metal-ceramic restorations were delivered three months after implant insertion (T2), and patients were recalled after six months (T3) and twelve months (T4) of prosthetic loading. Periapical radiographs were acquired at each time point. Bone levels were measured at each time point on both mesial and distal aspects of implants. Linear mixed models were fitted to the data to identify predictors associated with MBL. Fifty patients (25 male, 25 female; mean age 58.0 ± 12.8) with a total of 83 implants were included in the final analysis. The mean subcrestal position of the implant shoulder at baseline was 1.24 ± 0.57 mm, while at T4, it was 0.46 ± 0.59 mm under the bone level. Early marginal bone remodeling was significantly influenced by implant insertion depth and factors related to biological width establishment (vertical mucosal thickness, healing, and prosthetic abutment height). Deep implant insertion, thin peri-implant mucosa, and short abutments were associated with greater marginal bone loss up to six months after prosthetic loading. Peri-implant bone levels tended to stabilize after this time, and no further marginal bone resorption was recorded at twelve months after implant loading.

Abstract
The relationship between left ventricular ejection fraction (LVEF) and outcomes after cardiac rehabilitation (CR) is not well established; therefore we assessed the prognostic role of LVEF at the end of ambulatory CR program in patients (pts) who received coronary revascularization. LVEF was evaluated at hospital discharge and re-assessed at the end of CR in all ST-elevation myocardial infarction and coronary artery bypass graft pts, while in pts with non-ST-elevation MI or elective percutaneous coronary intervention the echocardiography was repeated if they had an impaired LVEF at discharge. New hospitalizations for cardiovascular causes at 1-year, and cardiovascular mortality during long-term follow-up were analyzed. We enrolled in CR 3078 pts, 86% showed LVEF ≥40% and 9% LVEF <40%. Of those with a discharge LVEF <40%, 56% improved LVEF (LVEF ≥40%) after CR. At 1-year, heart failure was the main cause of new hospitalizations in LVEF <40% group compared with LVEF ≥40% group (5% vs 0.4%, p <0.01). During a mean follow up of 48 ± 25 months, cardiovascular death occurred in 9% of pts with LVEF <40% and in 2% with LVEF ≥40% (p = 0.014). At Cox multivariate analysis, LVEF <40% at the end of CR and age were independent predictors of hospitalization and mortality for cardiovascular causes, while coronary artery bypass graft was a protective factor. In conclusion, during CR the improvement of LVEF occurs in a relevant proportion of patients, the re-assessment of LVEF at the end of the CR is helpful for risk stratification because left ventricle dysfunction at the end of CR is associated with worse cardiovascular outcomes.

Abstract
BACKGROUND Cardiac rehabilitation (CR) is a model of care proven to reduce mortality and morbidity in patients with coronary artery disease. The aim of this study is to describe the ambulatory CR model of the Cardiovascular Department of Trieste (Italy), analyzing the outcome of the population. METHODS We analyzed clinical and instrumental characteristics of all consecutive patients after ST-elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI), coronary artery bypass graft with or without valve surgery (CABG/CABGV), or planned percutaneous coronary intervention (PCI), referred for CR from January 1, 2009, to December 31, 2015. All patients were included in a registry. During CR and at 1-year follow-up, the incidence of new hospitalizations due to cardiovascular causes was assessed. Total and cardiovascular mortality was also evaluated at longer follow-up. RESULTS Overall, 3088 patients (28% female, mean age 70 ± 11 years; 35% older than 75 years) were referred for CR, 30% after STEMI, 23% after NSTEMI, 29% after CABG/CABGV, and 19% after PCI. At enrollment, 9% of patients had an ejection fraction <40%, 76% were hypertensive, 61% dyslipidemic, 19% diabetics, and 27% smokers. CR lasted 5 ± 4 months. At the end of the CR program, 96% of patients were on antiplatelets, 79% on beta-blockers, 73% on angiotensin-converting enzyme inhibitors, 25% on angiotensin II receptor blockers, and 87% on statins with achievement of the following secondary prevention targets: LDL cholesterol 85 ± 30 mg/dl, glycated hemoglobin 7.2 ± 4%, heart rate 64 ± 11 bpm, systolic/diastolic blood pressure 137 ± 32/78 ± 14 mmHg. During CR, new hospitalizations occurred in 11% of patients, 1% within 1 year after CR. At a mean follow-up of 4.4 ± 2 years, 11% of patients died, 3% for cardiovascular causes, 0.7% within 1 year. Cardiovascular mortality was significantly higher in elderly patients (6 vs 2%, p=0.000), women (4 vs 3%, p=0.038), diabetics (5 vs 3%, p=0.004), and in patients with left ventricular dysfunction (8 vs 3%, p=0.000). CONCLUSIONS Our findings show the feasibility of a CR program in an unselected population, characterized by advanced age, risk factors and comorbidities. A critical analysis of the registry data allowed us to achieve good results in secondary prevention and outcomes.

Abstract
Abstract
Background
To evaluate if procalcitonin (PCT) measurements made using the new point-of-care testing (POCT) ichroma™ are interchangeable with those made using Kryptor.
Methods
Serum samples (n = 117) were processed sequentially on Kryptor and ichroma™. Statistical analysis was performed using Passing-Bablok (PB) regression and the Bland-Altman (BA) test. Cohen’s kappa statistic was used to calculate the concordance at the clinically relevant cutoffs.
Results
PB regression did not show a significant deviation from linearity; proportional and constant differences were observed between ichroma™ and Kryptor. The 95% confidence interval (CI) of the mean bias percentage was very large, exceeding the maximum allowable total error (TE) (approximately 20%) and the clinical reference change value (about 60%). However, the concordance between methods at the clinically relevant cutoffs was strong, with the exception of the 0.25 ng/mL cutoff, which was moderate.
Conclusions
Our data suggest that ichroma™ is not interchangeable with Kryptor, so cannot be mixed; one must choose one instrument only and be consistent. However, while the strong concordance at the clinically relevant cutoffs allows us to consider ichroma™ a suitable option to Kryptor to support clinicians’ decision-making, nevertheless the moderate agreement at the 0.25 ng/mL cutoff recommends caution in interpreting the data around this cutoff.

Abstract
Right ventricular involvement in inferior myocardial infarction (MI) was historically associated with a poor prognosis. However, few studies addressed the impact of right ventricular (RV) dysfunction in the primary percutaneous intervention (pPCI) era. Our aim was to assess the prognostic significance of RV dysfunction in right coronary artery (RCA) related MI treated with pPCI. METHODS A total of 298 patients with a RCA related MI undergone pPCI between January 2011 and June 2015 were included. RV dysfunction was defined by a RV-FAC <35% at echocardiographic examination and further divided into mild (RV-FAC between 35 and 25%) and moderate-severe (RV-FAC <25%). RV function before discharge was reassessed in 95% of the study cohort. The primary endpoint was overall mortality. Median follow-up was 29 months. RESULTS In RCA related MI, moderate-severe (HR 5.882, p = 0.002, 95% CI 1.882-18.385) but not mild RV dysfunction independently predicted lower survival at follow-up along with age (HR 1.104, p <0.001, CI 1.045-1.167). Importantly, patients recovering RV function at discharge showed a lower mortality (p = 0.001) vs patients with persistent moderate-severe RV dysfunction) that approached the risk of patients without RV dysfunction at presentation. CONCLUSION In RCA related MI treated with pPCI, RV dysfunction was one of the strongest independent predictor of lower overall survival. However, patients with only transient RV dysfunction showed a better prognosis compared to patients who had persistent RV dysfunction. The focus on intensive support management of the RV in the first hours after pPCI may be important to overcome the acute phase and to promote RV recovery.

Abstract
Aims: Despite continuous efforts in improving the selection process, the rate of non-responders to cardiac resynchronization therapy (CRT) remains high. Recent studies on intraventricular blood flow suggested that the alignment of hemodynamic forces (HDFs) may be a reproducible biomarker of mechanical dyssynchrony. We aimed to explore the relationship between pacing-induced realignment of HDFs and positive response to CRT. Methods and results: We retrospectively analyzed 38 patients from the CRT database of our institution fulfilling the inclusion criteria for HDFs-related echocardiographic assessment early pre and post CRT implantation, with available mid-term follow-up (≥ 6 months) evaluation. Standard echocardiographic and deformation parameters early pre and post CRT implantation were integrated with the measurement of HFDs through novel methods based on speckle-tracking analysis. At midterm follow-up 71% of patients were classified as responders (reduction of Left Ventricular Systolic Volume Indexed ≥ 15%). Patients did not display significant changes between close evaluations pre and post-implant in terms of ejection fraction and strain metrics. A significant reduction of the ratio between the amplitudes of transversal and longitudinal force components was found. The variation of this ratio strongly correlates (R2 =0.60) with Left Ventricular (LV) end-systolic volume variation at mid-term follow up. Conclusion: Pacing-induced realignment of HDFs is associated with CRT efficacy at follow up. These preliminary results claim for dedicated prospective clinical studies testing the potential impact of HDFs study for patient selection and pacing optimization in CRT.

Abstract
BACKGROUND Persistent left ventricular (LV) systolic dysfunction in patients with acute lymphocytic myocarditis (LM) is widely unexplored. OBJECTIVES To assess the frequency and predictors of persistent LV dysfunction in patients with LM and reduced LVEF at admission. METHODS AND RESULTS We retrospectively evaluated 89 consecutive patients with histologically-proven acute myocarditis enrolled at three Italian referral hospitals. A subgroup of 48 patients with LM, baseline systolic impairment and an available echocardiographic assessment at 12 months (6-18) from discharge constituted the study population. The primary study end-point was persistent LV dysfunction, defined as LVEF <50% at 1-year, and was observed in 27/48 patients (56.3%). Higher LV end-diastolic diameter at admission (odds ratio [OR] 1.22, 95% confidence interval [CI] 1.04-1.43, p = 0.002), non-fulminant presentation (OR 8.46, 95% CI 1.28-55.75, p = 0.013) and presence of a poor lymphocytic infiltrate (OR 12.40, 95% CI 1.23-124.97, p = 0.010) emerged as independent predictors of persistent LV dysfunction at multivariate analysis (area under the curve 0.91, 95% CI 0.82-0.99). Pre-discharge LVEF was lower in patients with persistent LV dysfunction compared to the others (32%±8 vs. 53%±8, p <0.001), and this single variable showed the best accuracy in predicting the study end-point (area under the curve 0.95, 95% CI 0.89-1.00). CONCLUSIONS More than half of patients presenting with acute LM and LVEF <50% who survive the acute phase show persistent LV dysfunction after 1-year from hospital discharge. Features of subacute inflammatory process and of established myocardial damage at initial hospitalization emerged as predictors of this end-point.

Abstract
BACKGROUND The administration of endovenous immunoglobulins in patients with septic shock could be beneficial and preparations enriched with IgA and IgM (ivIgGAM) seem to be more effective than those containing only IgG. In a previous study Berlot et al. demonstrated that early administration of ivIgGAM was associated with lower mortality rate. We studied a larger population of similar patients aiming either to confirm or not this finding considering also the subgroup of patients with septic shock by multidrug-resistant (MDR) pathogens. METHODS Adult patients with septic shock in intensive care unit (ICU) treated with ivIgGAM from August 1999 to December 2016 were retrospectively examined. Collected data included the demographic characteristics of the patients, the diagnosis at admission, SOFA, SAPS II and Murray Lung Injury Score (LIS), characteristics of the primary infection, the adequacy of antimicrobial therapy, the delay of administration of ivIgGAM from the ICU admission and the outcome at the ICU discharge. Parametric and nonparametric tests and logistic regression were used for statistic analysis. RESULTS During the study period 107 (30%) of the 355 patients died in ICU. Survivors received the ivIgGAM earlier than nonsurvivors (median delay 12 vs 14 h), had significantly lower SAPS II, SOFA and LIS at admission and a lower rate of MDR- and fungal-related septic shock. The appropriateness of the administration of antibiotics was similar in survivors and nonsurvivors (84 vs 79%, respectively, p: n.s). The delay in the administration of ivIgGAM from the admission was associated with in-ICU mortality (odds ratio per 1-h increase = 1.0055, 95% CI 1.003-1.009, p < 0.001), independently of SAPS II, LIS, cultures positive for MDR pathogens or fungi and onset of septic shock. Only 46 patients (14%) had septic shock due to MDR pathogens; 21 of them (46%) died in ICU. Survivors had significantly lower SAPS II, SOFA at admission and delay in administration of ivIgGAM than nonsurvivors (median delay 18 vs 66 h). Even in this subgroup the delay in the administration of ivIgGAM from the admission was associated with an increased risk of in-ICU mortality (odds ratio 1.007, 95% CI 1.0006-1.014, p = 0.048), independently of SAPS II. CONCLUSIONS Earlier administration of ivIgGAM was associated with decreased risk of in-ICU mortality both in patients with septic shock caused by any pathogens and in patients with MDR-related septic shock.

Early occurrence of drug intolerance as risk factor during follow-up in patients with acute coronary syndrome or coronary revascularization. EUROPEAN HEART JOURNAL. CARDIOVASCULAR PHARMACOTHERAPY 2018; 4:195-201. [PMID: 29846559 DOI: 10.1093/ehjcvp/pvy017] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/12/2018] [Accepted: 05/18/2018] [Indexed: 12/18/2022]
Abstract
Aims The occurrence of drug intolerance (DI) after an acute coronary syndrome (ACS) or percutaneous coronary intervention (PCI) is an important reason for quitting treatment. Nevertheless, the association between DI and major cardiac and cerebrovascular events (MACCE) is poorly reported in the literature, therefore, we analysed potential relationship between DI and MACCE (a composite of ACS, PCI, heart failure, and stroke) during follow-up. Methods and results From 1 January 2014 to 31 December 2015, 891 consecutive patients after ACS or coronary revascularization were referred to cardiac rehabilitation (CR) programme and included in a dedicated registry where DI was analysed and treatment appropriately tailored. Three hundred and nine patients (34.7%) developed DI, 26.9% of them were female. Angiotensin-converting enzyme (ACE) inhibitors and statins were the most frequent drugs which caused DI, followed by beta-blockers and calcium channel blockers, in 13.1%, 12.8%, 7.5%, and 5.5% of patients, respectively. During a median follow-up of 18 (interquartile range 11-24) months after CR, MACCE occurred in 14.1% of patients with DI and 8.1% without DI (P = 0.007). At multivariable model, DI to 1 drug [odds ratio (OR) 1.8, 95% confidence interval (CI) 1.01-3.18; P = 0.043] or to 2 drugs (OR 2.56, 95% CI 1.27-5.17; P = 0.008) were independently associated to MACCE. Regarding the association of specific class of prognostic drugs to MACCE, only DI to ACE-inhibitors was independently associated with MACCE (OR 2.31, 95% CI 1.14-4.65; P = 0.019). Conclusion DI was frequently encountered in real-world clinical practice and was significantly associated with MACCE during follow-up. This study suggests that early occurrence of DI could be considered to be an adjunctive cardiovascular risk factor during secondary prevention.
