Hiatal Hernia: The Great Masquerade in the Emergency Department.

Chest pain and dyspnoea are among the most common complaints seen in the emergency room and each symptom calls for a broad differential diagnosis. Large hiatal hernias are infrequent, but they can lead to atypical symptoms mimicking different cardiovascular, pulmonary and neoplastic diseases. We present two cases of older patients with an apparent left atrial mass on transthoracic echocardiography, which was subsequently identified as hiatal hernia by other imaging modalities. A multidisciplinary team with multimodality imaging is necessary for diagnostic work-up of chest pain and dyspnoea of non-cardiac origin and especially for a suspected mass compressing the heart, causing chest discomfort. LEARNING POINTS: Hiatal hernia (HH) can mimic different cardiovascular, pulmonary and neoplastic diseases.HH has a typical echocardiographic (2DE) presentation as an amorphous, echolucent mass with the appearance of a left atrial space-occupying lesion.Oral ingestion of a carbonated drink may help to distinguish between a large HH and an atrial mass by 2DE.

Global longitudinal strain as a marker for systolic function in patients with pheochromocytomas.

Cardiomyopathy is a frequent complication of pheochromocytoma, and echocardiography is the most accessible method for its evaluation. The objective of this study was to assess the clinical significance of classical and novel echocardiographic parameters of cardiac function in 24 patients with pheochromocytomas (PPGL) compared to 24 subjects with essential hypertension (EH). Fourteen PPGL patients were reassessed after successful surgery. Left ventricular hypertrophy was four times more prevalent in patients with PPGL vs EH (75% vs 17%; P = 0.00005). Left ventricular mass index (LVMi) significantly correlated with urine metanephrine (MN) (rs = 0.452, P = 0.00127) and normetanephrine (NMN) (rs = 0.484, P = 0.00049). Ejection fraction (EF) and endocardial fractional shortening (EFS) were normal in all participants and did not correlate with urine metanephrines. Global longitudinal strain (GLS) was significantly lower in PPGL compared to EH group (-16.54 ± 1.83 vs -19.43 ± 2.19; P < 0.00001) and revealed a moderate significant positive correlations with age (rs = 0.489; P = 0.015), LVMi (rs = 0.576, P < 0.0001), MN (rs = 0.502, P = 0.00028) and NMN (rs = 0.580, P < 0.0001). Relative wall thickness (RWT) showed a strong positive correlation with urine MN (rs = 0.559, P < 0.0001) and NMN (rs = 0.689, P < 0.00001). Markedly decreased LVMi (118.2 ± 26.9 vs 102.9 ± 22.3; P = 0.007) and significant improvement in GLS (-16.64 ± 1.49 vs -19.57 ± 1.28; P < 0.001) was observed after surgery. ΔGLS depended significantly on the follow-up duration. In conclusion, classical echocardiographic parameters usually used for assessment of systolic cardiac function are not reliable tests in pheochromocytoma patients. Instead, GLS seems to be a better predictor for the severity and the reversibility of catecholamine-induced myocardial function damage in these subjects. RWT should be measured routinely as an early indicator of cardiac remodeling.

Efficacy and Safety of Ticagrelor Over Time in Patients With Prior MI in PEGASUS-TIMI 54.

BACKGROUND: Ticagrelor reduces ischemic risk in patients with prior myocardial infarction (MI). It remains unclear whether ischemic risk and the benefits of prolonged P2Y12 inhibition in this population remain consistent over time. OBJECTIVES: The study sought to investigate the pattern of ischemic risk over time and whether the efficacy and safety of ticagrelor were similar early and late after randomization. METHODS: The PEGASUS-TIMI (Prevention of Cardiovascular Events in Patients with Prior Heart Attack Using Ticagrelor Compared to Placebo on a Background of Aspirin-Thrombolysis In Myocardial Infarction) 54 trial randomized patients with prior MI (median 1.7 years prior) to ticagrelor 90 mg, ticagrelor 60 mg, or placebo on a background of aspirin. The rates of cardiovascular (CV) death, MI, and stroke as well as TIMI major bleeding were analyzed at yearly landmarks (years 1, 2, and 3). RESULTS: A total of 21,162 patients were randomized and followed for 33 months (median), with 28% of patients ≥5 years from MI at trial conclusion. The risk of CV death, MI, or stroke in the placebo arm remained roughly constant over the trial at an ∼3% annualized rate. The benefit of ticagrelor 60 mg was consistent at each subsequent landmark (year 1 hazard ratio [HR]: 0.82; 95% confidence interval [CI]: 0.67 to 0.99; year 2 HR: 0.90; 95% CI: 0.74 to 1.11; and year 3 HR: 0.79; 95% CI: 0.62 to 1.00). TIMI major bleeding was increased with ticagrelor 60 mg at each landmark, but with the greatest hazard in the first year (year 1 HR: 3.22; year 2 HR: 2.07; year 3 HR: 1.65). CONCLUSIONS: Patients with a history of MI remain at persistent high risk for CVD, MI, and stroke as late as 5 years after MI. The efficacy of low-dose ticagrelor is consistent over time with a trend toward less excess bleeding.

ScreenPro FH - Screening Project for Familial Hypercholesterolemia in Central, Southern and Eastern Europe: Rationale and Design.

Familial hypercholesterolemia (FH) is a genetic disorder with well-known genetic transmission and clinical course. Despite great recent progress, FH is still underestimated, under-diagnosed and thus undertreated. Furthermore it represents a significant healthcare challenge as a common risk factor for the premature development of coronary heart disease. The ScreenPro FH Project is an international network project aiming at improving complex care - from timely screening, through diagnosis to up-to-date treatment of familial hypercholesterolemia in Central, Eastern and Southern Europe. An important task for the project is to harmonise and unify diagnostic and therapeutic approaches in participating countries, where the situation differs from country to country. Countries with more experience should serve as a model for countries developing the FH network.Key words: diagnosis - familial hypercholesterolemia - screening - treatment optimization.

ScreenPro FH - Screening Project for Familial Hypercholesterolemia in Central, Southern and Eastern Europe: Basic Epidemiology.

INTRODUCTION: Despite great recent progress, familial hypercholesterolemia (FH) is still underestimated, under-diagnosed and thus undertreated worldwide. We have very little information on exact prevalence of patients with FH in the Central, Eastern and Southern Europe (CESE) region. The aim of the study was to describe the epidemiological situation in the CESE region from data available. METHODS: All local leaders of the ScreenPro FH project were asked to provide local data on (a) expert guess of FH prevalence (b) the medical facilities focused on FH already in place (c) the diagnostic criteria used (d) the number of patients already evidenced in local database and (e) the availability of therapeutic options (especially plasma apheresis). RESULTS: With the guess prevalence of FH around 1 : 500, we estimate the overall population of 588 363 FH heterozygotes in the CESE region. Only 14 108 persons (2.4 %) were depicted in local databases; but the depiction rate varied between 0.1 % and 31.6 %. Only four out of 17 participating countries reported the the LDL apheresis availability. CONCLUSION: Our data point to the large population of heterozygous FH patients in the CESE region but low diagnostic rate. However structures through the ScreenPro FH project are being created and we can hope that the results will appear soon.Key words: diagnosis - epidemiology - familial hypercholesterolemia - screening.

Efficacy and safety of ticagrelor for long-term secondary prevention of atherothrombotic events in relation to renal function: insights from the PEGASUS-TIMI 54 trial.

AIMS: We evaluated the relationship of renal function and ischaemic and bleeding risk as well as the efficacy and safety of ticagrelor in stable patients with prior myocardial infarction (MI). METHODS AND RESULTS: Patients with a history of MI 1-3 years prior from PEGASUS-TIMI 54 were stratified based on estimated glomerular filtration rate (eGFR), with <60 mL/min/1.73 m(2) pre-specified for analysis of the effect of ticagrelor on the primary efficacy composite of cardiovascular death, MI, or stroke (major adverse cardiovascular events, MACE) and the primary safety endpoint of TIMI major bleeding. Of 20 898 patients, those with eGFR <60 (N = 4849, 23.2%) had a greater risk of MACE at 3 years relative to those without, which remained significant after multivariable adjustment (hazard ratio, HRadj 1.54, 95% confidence interval, CI 1.27-1.85, P < 0.001). The relative risk reduction in MACE with ticagrelor was similar in those with eGFR <60 (ticagrelor pooled vs. placebo: HR 0.81; 95% CI 0.68-0.96) vs. ≥60 (HR 0.88; 95% CI 0.77-1.00, Pinteraction = 0.44). However, due to the greater absolute risk in the former group, the absolute risk reduction with ticagrelor was higher: 2.7 vs. 0.63%. Bleeding tended to occur more frequently in patients with renal dysfunction. The absolute increase in TIMI major bleeding with ticagrelor was similar in those with and without eGFR <60 (1.19 vs. 1.43%), whereas the excess of minor bleeding tended to be more pronounced (1.93 vs. 0.69%). CONCLUSION: In patients with a history of MI, patients with renal dysfunction are at increased risk of MACE and consequently experience a particularly robust absolute risk reduction with long-term treatment with ticagrelor.

Osteoprotegerin predicts progression of chronic heart failure: results from CORONA.

BACKGROUND: Osteoprotegerin (OPG) may be implicated in the pathogenesis of heart failure (HF), and circulating levels predict survival in patients with postinfarction HF. Our primary goal was to determine whether OPG provided independent prognostic information in patients with chronic HF, and to examine its potential interactions with statin therapy. METHODS AND RESULTS: OPG as a risk factor for the primary end point (cardiovascular death, nonfatal myocardial infarction, nonfatal stroke; n=318), all-cause mortality (n=329), and all-cause mortality/hospitalization for worsening of heart failure (WHF; n=475) was investigated in 1464 patients (≥60 years, New York Heart Association class II to IV, ischemic systolic HF, optimal pharmacological therapy) in the Controlled Rosuvastatin Multinational Trial in HF (CORONA) population, randomly assigned to 10 mg rosuvastatin or placebo. In multivariate analyses, OPG (continuous variable) added no significant predictive information for risk estimation of the primary end point (adjusting for left ventricular ejection fraction, New York Heart Association class, age, body mass index, diabetes, sex, intermittent claudication, heart rate, serum creatinine, apoA1, and N-terminal pro-B-type natriuretic peptide). However, OPG added independent predictive information for WHF hospitalization (hazard ratio [HR] 1.10 [1.04 to 1.16], P<0.001) and all-cause mortality/WHF hospitalization (HR 1.06 [1.01 to 1.11]). The HR indicated a reduced risk for all-cause mortality in the rosuvastatin group in those with lowest OPG values (tertile 1, HR=0.66 unadjusted [P=0.025]; HR=0.71 Cox adjusted [P=0.025]; interaction by treatment effect for the tertiles P=0.086). CONCLUSIONS: OPG added no predictive information for the primary end point, but independently predicted WHF hospitalization in older patients with advanced chronic systolic HF of ischemic etiology.

Right atrial thrombus from inferior vena cava after acute cardiotoxicity of 5-fluorouracil.

We reported a case of large right atrial thrombus which migrated from the inferior vena cava after acute left ventricular dysfunction due to 5-Fluorouracil cardiotoxicity. The patient had recurrent episodes of chest pain and dyspnea suggestive of pulmonary thromboembolism and several days later control echocardiography showed that the right atrial thrombus had disappeared. The patient was discharged with oral anticoagulant therapy with no further clinical sequelae during an 11 month period but died because of progression of metastatic processes. We hypothesized that initial congestive heart failure had been a provocative factor for thromboembolic events from previous thrombus formation at the inferior vena cava.

Effects of low dose hormone replacement therapy on markers of inflammation in postmenopausal women.

OBJECTIVE: Concentrations of soluble fractions of cell adhaesion molecules [sCAM], C-reactive protein (CRP) and serum amyloid A (SAA) are predictive for future cardiovascular events in postmenopausal women. The effect of hormone replacement therapy (HRT) on these inflammatory markers is not uniform. In the presented study the effect of a low-dose HRT preparation, on sCAM, CRP and SAA in healthy postmenopausal women was evaluated. METHODS: Serum levels of intracellular adhesion molecules (sICAM-1), vascular cell adhesion molecules (sVCAM-1), P-selectin, CRP and SAA were measured at baseline and after 12 weeks of treatment with continuous combined HRT containing 1 mg micronized 17beta-estradiol and 0.5 mg norethisterone acetate. The concentrations of total cholesterol, triglycerides LDL-cholesterol and HDL-c were measured as well. RESULTS: The studied low dose continuous combined therapy significantly reduced the concentration of sICAM-1, sVCAM-1 and P-selectin by 25.3, 20 and 34%, respectively. Despite statistically not significant the concentration of CRP and SAA increased by 35.6 and 9.4%, respectively. A statistically significant decrease in the triglycerides and TC/HDL-cholesterol ratio has been found. CONCLUSIONS: The outcomes of the presented study suggest that HRT with low dose continuous combined HRT containing 1 mg micronized 17beta-estradiol and 0.5 mg norethisterone acetate have divergent effects on studied parameters of vascular inflammation. These effects are similar to effects of other studied HRT combinations. To our best knowledge this is the first study evaluating the effect of HRT on the concentration of SAA.
