INTRODUCTION Myocardial infarction (MI) is the damage to the heart muscle, or myocardium, resulting from the lack of blood flow to the heart. MI patients experience mental and emotional problems such as depression and anxiety. These complications could cause delay in resuming work, decreased quality of life and increased risk of death. The role of education in facilitating adaptation is very im...
AIMS Sepsis-induced myocardial depression (SIMD), an early and frequent event of infection-induced systemic inflammatory response syndrome (SIRS), is characterized by reduced contractility irrespective of enhanced adrenergic stimulation. Phosphoinositide-3 kinase γ (PI3Kγ) is known to prevent β-adrenergic overstimulation via its scaffold function by activating major cardiac phosphodiesterases a...
BACKGROUND T-wave abnormalities are common during the acute phase of non-ST-segment elevation acute coronary syndromes, but mechanisms underlying their occurrence are unclear. We hypothesized that T-wave abnormalities in the presentation of non-ST-segment elevation acute coronary syndromes correspond to the presence of myocardial edema. METHODS AND RESULTS Secondary analysis of a previously e...
The mechanisms by which endotoxemia causes cardiac depression have not been fully elucidated. The present study examined the involvement of nitric oxide (NO) in this pathology. Rats were infused with lipopolysaccharide (LPS) or saline, and the plasma and myocardial NO(2)(-) and NO(3)(-) (NOx) concentrations were measured before or 3, 6, and 24 h after treatment. The hearts were then immediately...
The objective was to evaluate the influence of the Nursing Consultation Protocol in aspects of anxiety and depression in patients after myocardial revascularization using the Hospital Anxiety and Depression scale (HAD). A randomized clinical trial developed in the outpatient clinic of a public hospital in Fortaleza-Ceará. One hundred and forty six patients, who underwent myocardial revasculariz...

To ascertain whether exercise testing might predict multivessel coronary disease and left ventricular aneurysm after a myocardial infarction, 154 patients with a single documented myocardial infarction who had both exercise testing and coronary angiography were grouped according to whether they had greater than or equal to 1 mm ST depression, greater than or equal to 1 mm ST elevation, or neith...
