The spatial and temporal changes of weather factors depend on geographical location, seasons and the time of the day. Our study examines the relationships of meteorological factors and the incidence of acute myocardial infarction (AMI). A retrospective analysis of patients diagnosed with AMI between 2000 and 2004 in Hungary (n = 81,956 patients) was carried out. ⋯ A positive correlation was shown between front movements and the number of events per season (r = 0.053). Average barometric pressure changes, the number of front movements and the number of AMI events also showed a nearly similar seasonal deviation. Our findings show that certain meteorological factors may be related to the onset of AMI, however other factors also play an important role.

Paroxysmal Mobitz type-I atrioventricular block Luciani-Wenckebach conduction, acute myocardial infarction and severe three vessels coronary artery disease.
Paroxysmal atrioventricular block has been reported in patients without acute coronary syndrome and without significant coronary artery stenosis, in patients with acute coronary syndrome and without significant coronary artery stenosis, in patients without acute coronary syndrome and with significant coronary artery stenosis and in patients with acute coronary syndrome and significant coronary artery stenosis. Conflicting roles for alternating periods of second degree atrioventricular block (also known as Mobitz I or Luciani-Wenckebach periodicity) have been reported. Both hypotheses have been reported, that paroxysmal Wenckebach periods are compatible with a benign prognosis and that paroxysmal Wenckebach periods are associated with hemodynamic deterioration. We present a case of paroxysmal Mobitz Type-I atrioventricular block Luciani-Wenckebach conduction in a 75-year-old Italian man with acute myocardial infarction and severe three vessels coronary artery disease.

The recurrence of tako-tsubo cardiomyopathy complicated by cardiogenic shock: a case report.
Tako-tsubo cardiomyopathy is a stress-related cardiomyopathy which occurs in postmenopausal women after severe emotional stress. Although no evidence supporting specific treatment with tako-tsubo cardiomyopathy has been established, the prognosis is considered favorable with normalization of wall motion abnormalities within weeks. In addition, recurrence of this syndrome seems to be rare. Now, we report a recurrent case of tako-tsubo cardiomyopathy complicated by cardiogenic shock after repeated emotional stress.

Pheochromocytoma crisis presenting with shock and tako-tsubo-like cardiomyopathy.
Pheochromocytoma usually presents with hypertension but it may also be an unusual aetiology of cardiogenic shock in order to catecholamine induced myocardial dysfunction. We report the devastating course of a patient with tako-tsubo like apical cardiomyopathy during pheocytoma crisis who presented with classical transient left ventricular apical ballooning 6 months before.

Vasovagal syncope in the Canon of Avicenna: the first mention of carotid artery hypersensitivity.
Ibn Sina, known as Avicenna in the West, was a celebrated Persian thinker, philosopher, and physician who is remembered for his masterpiece, The Canon of Medicine. The Canon that served as an essential medical encyclopedia for scholars in the Islamic territories and Europe for almost a millennium consisted of 5 books. In the third book, Avicenna described patients with symptoms of carotid hypersensitivity syndrome. ⋯ In this paper, we presented a brief account of Avicenna's life and works and discuss his description of the so-called carotid hypersensitivity syncope. Notwithstanding his loyalty to the Greek theory of humoralism, Avicenna set forth his own version of "theory of spirits" to explain the mechanism of this disease. An account of the theory of spirits is also given.
