Abstract

To investigate the similarities and differences of massive pulmonary embolism (MPE) diagnosed by hemodynamic or radiological criteria, and therefore to improve physician's awareness of MPE from different aspects. The data were collected from a prospective, multi-center study for pulmonary thromboembolism. Fifty-three cases of MPE diagnosed by hemodynamic criteria were enrolled into group A, which was defined as shock and/or hypotension [systemic arterial pressure < 90 mm Hg (1 mm Hg = 0.133 kPa) or a pressure drop > or = 40 mm Hg] for > 15 min without new-onset arrhythmia, hypovolemia, or sepsis. MPE based on radiological criteria were enrolled into group B (n = 176), which was defined as pulmonary artery obstruction with more than 2 lobes or 7 segments. The baseline data of the 2 groups showed no difference. Common clinical manifestations included dyspnea, increase of respiratory rate, and accentuation of P(2), no significant differences between the 2 groups. There were no differences in central pulmonary artery emboli, more than 50% pulmonary artery obstruction and pulmonary artery obstruction index by CTPA, and indirect signs of emboli by doppler echocardiography as well (P > 0.05). However, the incidences of palpitation, sy...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
