Insights

Echocardiography can predict atrial fibrillation (AF) in patients with transient ischemic attack (TIA). Larger left atrial volumes and depressed left ventricular function identified via echocardiography may indicate AF risk.

Area of Science:

  • Cardiology
  • Neurology
  • Medical Imaging

Background:

  • Atrial fibrillation (AF) is a common arrhythmia that increases stroke risk.
  • Transient ischemic attack (TIA) is a warning sign for future stroke, often associated with AF.
  • Non-invasive methods to predict AF in TIA patients are crucial for timely intervention.

Purpose of the Study:

  • To investigate echocardiographic parameters for predicting AF in TIA patients.
  • To assess the relationship between left atrial (LA) and left ventricular (LV) function and AF detection.
  • To determine if echocardiography can guide AF monitoring strategies in TIA patients.

Main Methods:

  • 110 TIA patients without prior stroke or AF underwent echocardiography.
  • Patients were monitored using ECG, 72-hour Holter, and implantable cardiac monitors (ICM).
  • Echocardiographic parameters including LA volume, LA emptying fraction, LV ejection fraction, and LV global longitudinal strain were analyzed.

Main Results:

  • AF was detected in 14 patients (12.7%) during follow-up.
  • Patients with AF showed significantly larger LA volumes (2D and 3D) and depressed LA function (LA emptying fraction).
  • AF patients also exhibited depressed LV function, including lower LV ejection fraction and reduced LV global longitudinal strain.

Conclusions:

  • Echocardiographic assessment of LA and LV size and function can noninvasively predict AF in TIA patients.
  • These findings suggest echocardiography may help identify TIA patients at higher risk for AF.
  • Echocardiographic data could potentially guide the intensity and duration of AF monitoring in TIA patients.

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Amyloid Fibrils03:03

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Acid Attack on Concrete01:21

Acid Attack on Concrete

When acids come into contact with concrete, they initiate a chemical reaction that dissolves the hydrated cement paste. This process leads to softening and structural weakening of the concrete. This issue is commonly observed in environments such as chimneys, sewers, and industrial settings. The severity of the damage increases as the pH of the water interacting with the concrete drops below 6.5. In particular, a pH under 4.5 can cause significant concrete damage.
The rate at which hydrogen...
