Comentário a «Será que a diferença na opacificação coronária corrigida medida por TC é preditora do fluxo coronário?»

Revista Portuguesa de Cardiologia, 2011
Objectives: A proof-of-concept study was undertaken to determine whether differences in corrected coronary opacification (CCO) within coronary lumen can identify arteries with abnormal resting coronary flow.

Does access to cardiac investigation and treatment contribute to social and ethnic differences in coronary heart disease? Whitehall II prospective cohort study [PDF]

, 2004
Objective: To determine whether access to cardiac procedures and drugs contributes to social and ethnic differences in coronary heart disease in a population setting. Design: Prospective study with follow up over 15 years.

Discovery of miRNAs unique to actively transcribed erythroparvovirus infection in heart failure patients

ESC Heart Failure, EarlyView.
Abstract Aims miRNAs, small non‐coding RNAs, play key roles in gene regulation, cell differentiation and tissue development. They influence viral infection outcomes by directly interacting with viral genomes or modifying the host microenvironment. This study demonstrates miRNAs' ability to selectively suppress transcriptionally active erythroparvovirus,

Roof‐dependent atrial flutter with epicardial conduction pathway masked by left atrium posterior wall debulking ablation

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
The 3D map shows a scarred area in the left atrial posterior wall. The left atrial posterior area and mitral isthmus line act as obstructions in the tachycardia. Propagation apparently shows a centrifugal pattern from LA inferoseptal area (yellow arrows).

Microvolt T‐wave alternans in early repolarization syndrome associated with ventricular arrhythmias: A case report

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Microvolt T‐wave alternans (MTWA) is a marker for the development of ventricular arrhythmias (VA), but its role in early repolarization (ER) syndrome remains unknown. MTWA was detected in a 90‐second 6‐lead electrocardiogram from an ER syndrome patient. On average, MTWA was 50 μV, higher than what was observed on healthy subjects.

Deep learning analysis of the myocardium in coronary CT angiography for identification of patients with functionally significant coronary artery stenosis

, 2017
In patients with coronary artery stenoses of intermediate severity, the functional significance needs to be determined. Fractional flow reserve (FFR) measurement, performed during invasive coronary angiography (ICA), is most often used in clinical ...

State of precision medicine for heart failure with preserved ejection fraction in a new therapeutic age

ESC Heart Failure, EarlyView.
Abstract Heart failure with preserved ejection fraction (HFpEF) is defined by heart failure (HF) with a left ventricular ejection fraction (LVEF) of at least 50%. HFpEF has a complex and heterogeneous pathophysiology with multiple co‐morbidities contributing to its presentation. Establishing the diagnosis of HFpEF can be challenging.

Identifying the culprit artery via 12‐lead electrocardiogram in inferior wall ST‐segment elevation myocardial infarction: A meta‐analysis

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Sometimes the easiest way is the best. Simple methods as ST‐segment elevation in III > II and ST‐segment depression in aVL > I are effective diagnostic test for identifying culprit artery in inferior wall ST‐segment elevation myocardial infarction. Complex algorithms are not superior to simple methods.

Randomized trial to assess worsening renal function by adding dapagliflozin for acute decompensated heart failure

ESC Heart Failure, EarlyView.
Abstract Aims Dapagliflozin (DAPA), a sodium‐glucose co‐transporter 2 inhibitor, has been shown to reduce cardiovascular mortality among patients with chronic heart failure. We aimed to evaluate the impact on a worsening renal function (WRF) by adding DAPA as compared to standard decongestive therapy with loop diuretics alone.

Association between the Tpeak‐Tend interval on admission and coronary microvascular dysfunction in Takotsubo syndrome

ESC Heart Failure, EarlyView.
Abstract Aims The Tpeak‐Tend interval on electrocardiogram may be a predictor of worse outcomes in Takotsubo syndrome (TTS), but the mechanisms have not been fully determined. This study aimed to investigate the relationships between the corrected Tpeak‐Tend (cTp‐e) interval and coronary microvascular‐dysfunction (CMD) assessed by the angiography ...
