RESUMO
AIM: To investigate the association between previous periodontal treatment and recurrent events after first-time myocardial infarction (MI). MATERIALS AND METHODS: From the Danish nationwide registries, patients with first-time MI between 2000 and 2015 were divided into three groups according to oral health care within 1 year prior to first-time MI. A multiple logistic regression model provided adjusted odds ratios (ORs) with 95% confidence intervals (CIs) to assess the 3-year risk of major adverse cardiovascular events (MACE). RESULTS: A total of 103,949 patients were included. Patients with treated periodontitis (PD) prior to first-time MI had an adjusted 3-year risk of MACE similar to patients presumed periodontally healthy (OR 0.97 [95% CI 0.92-1.03]). Patients with no prior dental visits were significantly older, had more comorbidities and showed significantly increased adjusted 3-year risks of MACE (OR 1.47 [95% CI 1.42-1.52]), cardiovascular death (OR 1.71 [95% CI 1.64-1.78]) and heart failure (OR 1.13 [95% CI 1.07-1.20]) compared with patients presumed periodontally healthy. CONCLUSIONS: Patients with treated PD 1 year prior to first-time MI had a similar risk of recurrent cardiovascular events as patients presumed periodontally healthy. No dental visit prior to first-time MI was an independent risk factor for recurrent events.

BACKGROUND: Anthracycline-based chemotherapy has improved the prognosis of various malignancies, but increases the long-term risk of heart failure (HF). Identification of patients at risk prior to treatment initiation is warranted. Therefore, the aim of this study was to evaluate if a familial predisposition to HF increases the risk of anthracycline related HF. METHODS: Using nationwide Danish registries, all patients treated with anthracycline from 2004 to 16 were identified. The primary outcome was long-term HF risk. First-degree relatives were identified in the Danish Family Registry and exposure was defined as a first-degree biological relative with prior HF. Risk of HF was evaluated in a cumulative incidence function and the association in a multivariable Cox regression model. RESULTS: A total of 11,651 patients (median age 49.1 years (IQR: 43.6-53.7), 12.2% male) were included after exclusion of 46 with preanthracycline HF. Median follow-up was 3.8 years (IQR 1.9-6.4). In the group with a first-degree relative with HF (n = 1,608) 35 patients (2.2%) were diagnosed with HF vs 133 (1.3%) in the group without a first-degree relative with HF (n = 10,043), corresponding to incidence rates per 1,000 patient-years of 5.2 (CI:3.8-7.3) vs 3.0 (CI:2.5-3.5). The cumulative incidence of HF after 10 years was higher in the first-degree relative group (3.2% vs 2.0%, P = .004); adjusted hazard ratio 1.53 (CI:1.05-2.23, P = .03). CONCLUSION: In this nationwide register-based study having a first-degree relative with HF was associated with increased risk of anthracycline related HF, suggesting that attention towards family predisposition may be warranted when estimating the risk of anthracycline related cardiotoxicity.
RESUMO
BACKGROUND: In the POET (Partial Oral Endocarditis Treatment) trial, oral step-down therapy was noninferior to full-length intravenous antibiotic administration. The aim of the present study was to perform pharmacokinetic/pharmacodynamic analyses for oral treatments of infective endocarditis to assess the probabilities of target attainment (PTAs). METHODS: Plasma concentrations of oral antibiotics were measured at day 1 and 5. Minimal inhibitory concentrations (MICs) were determined for the bacteria causing infective endocarditis (streptococci, staphylococci, or enterococci). Pharmacokinetic/pharmacodynamic targets were predefined according to literature using time above MIC or the ratio of area under the curve to MIC. Population pharmacokinetic modeling and pharmacokinetic/pharmacodynamic analyses were done for amoxicillin, dicloxacillin, linezolid, moxifloxacin, and rifampicin, and PTAs were calculated. RESULTS: A total of 236 patients participated in this POET substudy. For amoxicillin and linezolid, the PTAs were 88%-100%. For moxifloxacin and rifampicin, the PTAs were 71%-100%. Using a clinical breakpoint for staphylococci, the PTAs for dicloxacillin were 9%-17%.Seventy-four patients at day 1 and 65 patients at day 5 had available pharmacokinetic and MIC data for 2 oral antibiotics. Of those, 13 patients at day 1 and 14 patients at day 5 did only reach the target for 1 antibiotic. One patient did not reach target for any of the 2 antibiotics. CONCLUSIONS: For the individual orally administered antibiotic, the majority reached the target level. Patients with sub-target levels were compensated by the administration of 2 different antibiotics. The findings support the efficacy of oral step-down antibiotic treatment in patients with infective endocarditis.

Background: Patients with hypertrophic cardiomyopathy (HCM) are generally regarded as having increased risk of arrhythmia, stroke, heart failure, and sudden cardiac death, but reported mortality rates vary considerably and originate from selected populations. Study objective: We aimed to investigate the long-term mortality rate in a nationwide cohort of patients with HCM compared to a matched cohort from the general Danish population. Methods: All patients with a first-time HCM diagnosis in Denmark between January 1, 2007 and December 31, 2018 were identified through nationwide registries. In the main analysis, two visits in an outpatient clinic were required in order to increase specificity. Patients were matched to controls from the background population in a 1:3 ratio based on age, sex, selected comorbidities and date of HCM. Mortalities were compared using Kaplan Meier estimator and multivariable Cox regression models. Results: We identified 3126 patients with a first-time diagnosis of HCM. 1197 patients had at least two visits in the outpatient clinic (43 % female, median age 63.1 [25th-75th percentile 52.1-72.1] years). All-cause mortality was significantly higher in HCM patients than in matched controls: 10-year probabilities of death were 36.4 % (95 % CI 30.2-43.5 %) for HCM patients and 19.4 % (95 % CI 16.8-22.5 %) for controls. After adjusting for additional comorbidities and medications, a diagnosis with HCM was associated with an increased mortality rate (HR 1.48 (95 % CI 1.18-1.84, p = 0.001)). Conclusion: Compared to matched controls from the background population, presence of HCM was associated with a significant increase in mortality rate.
RESUMO
AIMS: Native valve aortic stenosis is associated with adverse remodelling of the left ventricle and remodelling is stopped or even reversed with aortic valve replacement (AVR). However, the degeneration of bioprostheses and development of structural valve deterioration (SVD) may affect this. METHODS AND RESULTS: To assess the association with SVD, remodelling and outcome 451 patients from a single surgical centre who had undergone AVR with a Mitroflow pericardial bioprosthesis were studied. All patients were assessed in 2014 and a subgroup of patients (N = 327) were re-exanimated again after at least 18 months [median time of 27 (interquartile range, IQR 26-33) months] including echocardiography, measurements of N-terminal pro-brain natriuretic peptide, and assessment of functional status. SVD was based on echocardiography. Moderate SVD was present in 63 patients (14%) and severe SVD in 19 (4%), in the subgroup with follow-up echocardiography 48 patients (15%) patients had moderate to severe SVD at first examination. Patients with SVD had significantly greater increase in left ventricular (LV) mass index [21.6 g/m2 (IQR 5.7-48.3 g/m2) vs. 9.1 g/m2 (-8.6 to 27.3 g/m2), P = 0.01]. Further, patients with SVD had lower LV ejection fraction [55% (IQR 51-62%) vs. 60% (IQR 54-63%), P = 0.01] at follow-up. During follow-up, 94 patients (21%) met the composite endpoint of death or reoperation due to SVD and 41 patient readmitted for heart failure. In multivariable Cox regression analysis, severe SVD [hazard ratio (HR) 2.64 (1.37-5.07), P = 0.004] was associated with composite endpoint, and readmission for heart failure [HR 3.82 (1.53-9.51), P = 0.004]. CONCLUSION: SVD in aortic bioprostheses is associated with adverse LV remodelling and adverse outcome.

AIM: Schizophrenia is associated with high cardiovascular mortality predominantly as a result of acute coronary syndrome (ACS). The aim of this study is to analyze time trends of coronary procedures, guideline-based therapy, and all-cause mortality in patients diagnosed with schizophrenia. METHODS AND RESULTS: This Danish nationwide register-based study analyzed 734 patients with a baseline diagnosis of schizophrenia and an incident diagnosis of ACS in the period between January 1, 1996, and December 31, 2015. The 734 patients with schizophrenia were matched to 2,202 psychiatric healthy controls (PHC). No change over time was seen in the relative difference between the population with schizophrenia and the PHC in the use of coronary angiography, percutaneous coronary intervention, and coronary bypass grafting, nor in 1-year mortality or guideline-based therapy following ACS. Patients with schizophrenia had higher prevalence rates of diabetes, chronic obstructive pulmonary disease, and stroke, and a lower prevalence of hypertension (p < 0.05). CONCLUSION: The gap in the use of coronary procedures, guideline-based therapy, and all-cause mortality following ACS in patients with schizophrenia compared to those without has remained constant over the past 2 decades.

A new Cochrane metaanalysis has reviewed the literature on the use of angiotensin receptor blockers (ARB) in patients with heart failure and left ventricular systolic dysfunction. The conclusion supports the present recommendation from the European Society of Cardiology that angiotensin converting enzyme inhibitors (ACE-I) are first choice and that ARBs should be reserved to patients who are intolerant to ACE-Is. Neither ACE-Is nor ARBs are effective in the treatment of heart failure patients with normal left ventricular function.
