AIM: To examine whether pulmonary artery balloon pulsation (PABP) could improve circulatory function in acute myocardial infarction (AMI) in pigs. METHODS/RESULTS: Ten downsize pigs were sedated and ventilated. AMI was induced by inserting a plug into the left anterior descending artery. A pulsation balloon was placed in the pulmonary artery in all animals. In the treatment group (TG), pulsations began when life-threatening arrhythmia or > 30% drop in mean blood pressure (MBP) or > 40% decrease in cardiac output compared to baseline occurred...

Extracorporeal shockwave myocardial revascularization (ESMR) is one of the new treatment options for refractory angina pectoris (RAP), and some studies have indicated its effectiveness. A single-arm prospective trial to assess the feasibility of ESMR using Cardiospec for patients with post-acute myocardial infarction (AMI) and RAP was designed and performed. The patients were treated with 9 sessions of ESMR to the ischemic areas for 9 weeks. The feasibility measures included echocardiography; cardiac magnetic resonance imaging; troponin T, creatine kinase-MB (CK-MB), and brain natriuretic peptide testing; and a Seattle Angina Questionnaire (SAQ) survey...

BACKGROUND: Treatment with renin-angiotensin system (RAS) inhibitors might restrain the structural/electrical remodeling associated with atrial fibrillation (AF). Limited evidence exists regarding the potential benefits of RAS inhibition post-acute myocardial infarction (AMI) in patients with AF. This study sought to assess the association between RAS inhibition and all-cause mortality and new-onset AF in patients with/without congestive heart failure (CHF) post-AMI. METHODS AND RESULTS: Patients hospitalized for AMI between 2006 and 2012 were identified in Swedish registries...

Cardiovascular diseases are a major public health problem because of their they impact on more than 30% of all deaths worldwide. In our country and in the Instituto Mexicano del Seguro Social (IMSS) are also the leading cause of death and the main cause of lost of healthy life years due to disability or premature death. 50% of deaths are premature; most of them are due to acute myocardial infarct. However, the investment for cardiovascular health is poor and there are no comprehensive cares programs focused on the treatment of this diseases or the control of their risk factors...

Rupture of the free wall of the left ventricle with the formation of a false aneurysm (pseudoaneurysm, PA) - is a rare complication of acute myocardial infarction. Given the high risk of rupture of the PA and other life-threatening consequences (progressive heart failure, thromboembolic events), as well as the absence of pathognomonic signs and the difficulty in determining treatment strategy (feasibility and timing of surgery), early diagnosis of this complication appears to be especially important. We present here an overview of literature data on prevalence, specific features of diagnostics, and problems related to selection of method of treatment of PA...

Hydrochlorothiazide became one of the most commonly prescribed first-line antihypertensive medication, though its use is often complicated with serious side-effects. A 66-year-old female patient with a history of hypertension had suffered a transient loss of consciousness, and referred to our cardiology unit with an ST-segment elevation and giant negative T-waves in V1-2 ECG leads, long QT-segment and elevated serum creatine-kinase (5392 U/L) and troponin I (4,357 ng/ml) levels. Acute myocardial infarction was not proven (later coronarography revealed preserved coronary circulation), but severe hyponatraemia and hypokalaemia was detected, explaining a possible symptomatic seizure, and which could be accounted for a 25 mg daily hydrochlorothiazide antihypertensive treatment and - as a precipitating insult - a one-week history of gastroenteritis...

Acute myocardial infarction (AMI) with development of ventricular fibrillation (VF) is a common cause of sudden cardiac death (SCD). At present, no pharmacological treatment has successfully been able to prevent VF in the acute stage of AMI. This study investigates the antiarrhythmic effect of inhibiting small conductance Ca(2+)-activated K(+) (SK) channels using the pore blocker N-(pyridin-2-yl)-4-(pyridin-2-yl)thiazol-2-amine (ICA) in AMI rats. Acute coronary ligation was performed in 26 anesthetized rats, and ECG, monophasic action potentials (MAPs), and ventricular effective refractory period (vERP) were recorded...

Several studies have identified the critical role of calcium-sensing receptors (CaSRs) in cardiac ischaemia/reperfusion injury and cardiac hypertrophy and have demonstrated that CaSRs induce myocardial apoptosis by activating MAPKs. Using acute myocardial infarction rat models, we found that a combination therapy of CaSR inhibition and embryonic stem cell (ESC) transplantation after acute myocardial infarction (AMI) leads to a dramatic reduction in the infarct size; a significant increase in the maximum rising and falling rate (+dp/dtmax and -dp/dtmax, respectively) of left ventricular pressure; a significant decrease in left ventricular end-diastolic pressure; a significant decrease in the mRNA expression level of CaSR, Bax, Bcl-2, cleaved caspase-3, cleaved caspase-9, p-ERK, p-JNK and p-P38 protein together with apoptosis indexes in the C and E groups; and a significant decrease in cTnT levels as well as LDH and CK activity...

Spontaneous coronary artery pseudoaneurysm (PSA, false aneurysm) is an extremely rare occurrence with the precise incidence unknown. It is defined as an outwardly bulging monolayer or double layer within the coronary artery that lacks all 3 layers (intima, media, and adventitia) of the arterial wall. Coronary PSA commonly occurs from arterial dissection or perforation induced by catheter intervention, infection, pregnancy, or trauma. Traumatic dissection or perforation of the coronary artery after a percutaneous coronary intervention (PCI) remains the most common cause...

Depression is a serious mental illness. To study the mechanisms of diseases and search for new, more effective therapies, animal models are used. Unfortunately, none of the available models does reflect all symptoms of depression. Zinc deficiency is proposed as a new animal model of depression. However, it has not been yet validated in a detailed manner. Recently, spectroscopic techniques are increasingly being used both in clinical and preclinical studies. Here we examined the effect of zinc deficiency and amitryptyline treatment on the phospholipid - protein balance in the blood serum of rats using Raman, Fourier Transform Infra Red (FTIR) and UV-vis technique...

Clinical outcomes in acute myocardial infarction (AMI) worsen with increasing delay between symptom onset and clinical presentation. Previous studies have shown that black patients with AMI have longer presentation delays. The objective of this analysis is to explore the potential contribution of community factors to presentation delays in black patients with AMI. We linked clinical data for 346,499 consecutive patients with AMI from Acute Coronary Treatment Intervention Outcomes Network Registry-Get With the Guidelines™ (2007-2014) to socioeconomic and community information from the American Community Survey...

BACKGROUND: Young women (≤55 years of age) with acute myocardial infarction (AMI) have higher mortality risk than similarly aged men. Elevated inflammatory markers are associated with an increased risk of cardiovascular outcomes after AMI, but little is known about whether young women have higher inflammatory levels after AMI compared with young men. METHODS AND RESULTS: We assessed sex differences in post-AMI inflammatory markers and whether such differences account for sex differences in 12-month health status, using data from 2219 adults with AMI, 18 to 55 years of age, in the United States...
