The brain-heart connection: a multiple sclerosis relapse presenting as Takotsubo Syndrome. A case report and literature review

We hereby report a puzzling case of multiple sclerosis (MS) relapse presenting as Takotsubo syndrome (TTS). Female, 42-years old, who presented herself to the Emergency Room of University Hospital "ASST Spedali Civili" of Brescia, Italy, for a severe headache and a non-ST-segment elevation acute coronary syndrome. Coronary angiogram showed no signs of coronary atherosclerosis. Upon further neurological evaluation, a diagnosis of MS relapse, related to TTS, was made, and treatment was started accordingly. The patient was discharged after 12 days after the admission, free of symptoms, and without signs of neurological and cardiological active disease. A hallmark of TTS is its association with a preceding stressful event. It may also be connected to a wide variety of diseases, including neurological ones, such as stroke, intracranial bleeding, head trauma, migraine, and seizures. However, up to our knowledge, only few cases of MS-induced TTS were previously described. Whether it is plausible to consider TTS as an uncommon extra-neurological manifestation of MS is still debated, however all the evidence points in that direction, considering the central role of catecholamines in TTS pathogenesis. With this case report the authors hope to encourage research on this field and on the intricate topic of brain-heart connections

Sodium–Glucose Cotransporter 2 Inhibitors in Heart Failure with Preserved Ejection Fraction: Rationale for and Practical Use of a Successful Therapy

Heart failure (HF) with preserved left ventricular ejection fraction is a common disease with a poor prognosis and rising prevalence in the community. The current paradigm of treatment includes symptomatic therapy, such as diuretics, and risk factor control and treatment of comorbidities. According to European guidelines, there is no effective therapy for patients with HF with left ventricular ejection fraction (LVEF) ≥50%, while drugs normally used in HF with reduced LVEF might also be effective for patients with mildly reduced LVEF (40–50%), with a IIB class of recommendation. The recently published EMPEROR-Preserved trial has challenged current guidelines, demonstrating improved outcomes in patients with HF and LVEF >40% with the sodium–glucose cotransporter 2 inhibitor (SGLT2I) empagliflozin, compared with placebo. This result was consistent in patients with and without diabetes as well as in those with LVEF below and above 50%. The authors describe the rationale for this therapy, presenting the main results of the EMPEROR-Preserved trial, and provide some recommendations for the everyday clinical management of HF with preserved left ventricular ejection with an SGLT2I

Is there a role for ivabradine beyond its conventional use

Summary Results of recent clinical trials in patients with stable angina and chronic heart failure have successfully demonstrated a beneficial role of use of ivabradine in addition to the conventional therapy. Based on the results of these trials, the aim of our review was to give an overview of the literature about the use of ivabradine in clinical settings outside its usual purpose

Red cell distribution width and chronic heart failure: prognostic role beyond echocardiographic parameters.

Aim. Red cell distribution width (RDW) is a measure of anisocytosis. Higher values are robustly associated to adverse outcome in several conditions, including chronic heart failure (HF). The present study aimed to compared its prognostic role with that of echocardiographic parameters in this kind of patients. Methods. 232 stable and optimally treated chronic HF patients were enrolled. We excluded subjects suffering from valvular diseases or atrial fibrillation. They underwent blood sampling and echocardiographic examination. The primary endpoint of the study was cardiovascular death and/or HF hospitalization in the first year after enrolment. Results. 49 patients reached the primary endpoint. RDW best cut-off at ROC curve was 14.45%. Univariate analysis associated mitral regurgitation grade, left ventricular ejection fraction (LVEF), posterior wall thickness (PWT), LV mass index, and RDW&gt;14.45% to the primary endpoint. Multivariate regression analysis showed that LVEF, PWT, and RDW&gt;14.45% predict the primary endpoint. Area under ROC curve was 0.808 for LVEF, 0.762 for NYHA class, and 0.761 for RDW. Conclusion. In chronic HF patients RDW is a better predictor of adverse outcome than several echocardiographic parameters associated to outcome itself (LV mass index, mitral regurgitation grade), predicts prognosis even adjusting for those parameters, age and NYHA class, and is associated to several echocardiographic measurements. In conclusion, RDW can expand our tool bag in order to better follow-up these patients.</p

The role of heart rate and ivabradine in acute heart failure.

Resting heart rate (HR) is considered a powerful predictor of mortality both in healthy subjects and in cardiovascular (CV) patients, including those affected by heart failure (HF). Its reduction below 70 bpm is the treatment target in chronic HF with reduced ejection fraction (HFrEF) when sinus rhythm is present. In acute HF (AHF) HR is usually elevated but its role as risk marker is still unknown. Notably, in unstable patients, beta-blockers can be reduced or stopped, thus enhancing this phenomenon. Moreover, some data in literature suggest that HR reduction during hospitalization or HR at discharge or in the vulnerable phase after it are more predictive of early-term events and may be therapeutic targets. On the other hand, ivabradine is a pure HR-lowering drug with no effects on inotropism. Its role in the AHF setting has been recently investigated and is the object of this review

Left ventricular function in rheumatoid arthritis during anti-TNF-α treatment: a speckle tracking prospective echocardiographic study

Aim. Rheumatoid arthritis (RA) shows a high risk for cardiovascular disease, including heart failure. Although TNF-α has been implicated in the pathogenesis of myocardial remodelling, TNF-α inhibition did not show any efficacy in patients with advanced heart failure and should be contraindicated in RA with cardiac complications. We aimed to assess global left ventricular (LV) systolic function using global longitudinal strain (GLS) as a measure of myocardial deformation, in a group of RA patients before and during anti-TNF-α treatment. Methods. 13 patients (female:male 7:6) affected by RA were prospectively followed for one year during anti TNF-α treatment. Every subject underwent echocardiography before starting anti-TNF-α drugs and after one year of treatment, to evaluate LV ejection fraction (EF), telediastolic diameter, telediastolic volume and global longitudinal strain (GLS) that was calculated using 2D speckle tracking as the mean GLS from three standard apical views (2, 3 and 4 -chambers). The patients showed a mean age of 43 years at RA onset (SD: 13) and a mean follow-up of 7.3 years (SD: 4.8). Steroid and methotrexate were used in 84.6% and 100%, respectively, in association with etanercept (6 cases), adalimumab (4 cases) and infliximab (3 cases). Results. Patients globally showed a normal EF before and after one year of treatment (mean: 65% and 65.7%, respectively). GLS did not differ before or after anti-TNF-α treatment (mean: -15.8% and -16.7%, respectively). Conclusion. Anti-TNF-α treatment did not significantly modify myocardial contractility after 12 months. </p

Wellens' syndrome: a case report with atypical features.

Wellens' syndrome is a pattern of electrocardiographic T-wave changes seen in the precordial leads in patients with unstable angina. Two different patterns have been described. Type A presents with biphasic T-waves in V2-V3 and type B presents with symmetrical deep T-wave inversions in V2-V3. The etiology is related to a critical stenosis in the proximal left anterior descending artery (LAD). We describe a patient who presented at our emergency department with intermittent chest pain and showing Wellens' pattern T-wave inversions in the precordial leads of the electrocardiogram. She was found to have 95% stenosis in mid LAD

A drastic complex atheromatous aorta A case report

Aortic atherosclerosis is the most common disease of the aorta. More than 50% of the plaques thicker than 4 mm are located along the descending aorta. The complex morphology of the plaque, such as ulceration or the presence of thrombi, is associated with increased embolic risk. The increasing use of transesophageal echocardiogram has enhanced the recognition of aortic atheromas. We describe a case of a male patient with complex atherosclerotic disease involving the coronary vessels and descending aortic tract with some embolic complications

Irreversible proteasome inhibition with carfilzomib as first line therapy in patients with newly diagnosed multiple myeloma: Early in vivo cardiovascular effects.

Patients who experienced cardiovascular side effects during cancer therapy with carfilzomib for multiple myeloma had relapsed multiple myeloma, so have be previously treated with other cancer therapies. The present is a single center cohort study to evaluate early cardiovascular effects of administration of irreversible proteasome inhibitor carfilzomib in naïve patients. We included 24 patients and collected cardiovascular side effects, echocardiographic parameters and endothelial function at baseline and after 4 cycles. At early follow up we observed increase in blood arterial pressure values (mean change in systolic pressure of 10 mmHg (P-value  0.01; diastolic arterial pressure and mean arterial pressure of 3.3 mmHg and 5.4 mmHg, both P-value  0.01). Reactive hyperemia PAT index was reduced in the whole cohort by a mean of 0.46 points (P-value  0.01); diastolic function was changed: E-wave-deceleration-time (EDT) was reduced by 49,96 ± 31 ms, P-value  0.05 and early diastolic tissue Doppler velocity (e') by a mean value of 1.46 cm/s, P - value 0.04. At early follow up we did not observe events of grade 3 or 4. We observe correlation between events and endothelial dysfunction at baseline and age (OR 1.9, CI 95% 0.05-5.804, P- value: 0.038 for RHI1.67; OR 1,4, CI 95%0.99-2.56, P- value: 0.04 for age). Our results suggest that therapy with carfilzomib when used as first line therapy is responsible for increase in systemic blood pressure, alteration of endothelium-mediated vascular dilatation and early myocardial diastolic dysfunction

An unusual case of myocardial infarction

Myocardial infarction may be the result of embolism of calcified material from the aortic valve or thrombotic formations adhering to the same. We report a case of late myocardial infarction secondary to embolization from a thrombus adherent to the aortic valve jutting out in the ostium of the left main coronary artery.
