The main aim of our study was to evaluate the prognostic utility of vitamin D measured as serum 25-hydroxyvitamin D [25(OH D] in a Norwegian coastal coronary chest-pain population exposed to temperate sun activity at low altitudes and with a high consumption of fish as reflected by the omega-3 index.
We have previously shown that 2- and 5-year total and cardiac mortality is decreased in the highest as compared to the lowest quartile of vitamin D in a coronary chest-pain population living at altitudes exceeding 1000 meters in subtropical northern Argentina [ 16], and this relationship is stronger in females than in males [ 17].
This is probably due to important similarities between this group and patients with a diagnosis of UA, in which copeptin levels have not been shown as significantly different from those of patients with non-coronary chest pain in most of the previous studies.
They excluded anyone who reported any previous coronary artery disease, chest pain, stroke or cancer, leaving 9,569 men and 14,112 women in the group they analyzed.
To evaluate the accessibility of coronary arteries from chest CT examinations acquired without ECG gating or beta-blockade.
The proportion of assessable coronary arteries on chest CTs will foreseeably follow the same path, since CT techniques and image quality will continue to improve.
Whereas cardiac CT is mainly indicated for triaging patients suspected of having coronary artery disease, chest CT should screen for asymptomatic coronary artery disease on a target zone (i.e. proximal and mid segments [17]) with the same data set as that used for the evaluation of the underlying respiratory disease.
Subjects who underwent coronary angiography for chest pain were consecutively enrolled.
Of the eight patients who developed cardiac toxicity, three developed atrial fibrillation and five developed coronary vasospasm and chest pain.
Of 315 elderly patients (mean age: 77.39 ± 6.33 years) who had undergone coronary angiography for chest distress, 297 exhibited sinus rhythm (SR), whereas 18 patients exhibited chronic AF.
From July 2006 to June 2009, 814 consecutive unrelated subjects, including 309 type 2 diabetic patients and 505 non-diabetic control subjects, were recruited at Taipei Veterans General Hospital from the patients scheduled to undergo coronary angiography for chest pain and/or suspected coronary artery disease.
