Clinical Appropriateness of Coronary Angiography
Background: The study evaluates the appropriateness of coronary angiography and the agreement between the used method and the presence of coronary artery disease by the indications proposed from American College of Cardiology/American Heart Association (1999). Method: The guidelines allow us to associate to Class I and IIa the judgment of appropriateness, to the Class IIb of uncertainty; to Class III of inappropriateness. Result: On 761 coronary angiography 76.74% were appropriate, 23.13% unsuitable, 0.13% uncertain. The group with the greater value of appropriateness is that one with unstable angina (97.9% appropriate); that one with the lower value is the group with non-specific symptomat…
Microvascular angina in diabetic patients with uninjured coronary arteries
Received 14 March 2012; Accepted 26 July 2012 Abstract: Aims: The study aims at the evaluation, of patients with chest pain and uninjured coronary arteries, and the impact of diabetes mellitus on coronary microcirculation. Moreover we want to verify whether a correlation between myocardial scintigraphy results and coronary angiography or not. Methods: The study population included 316 patients (173 males,143 females) with uninjured coronary arteries. Patients with chest pain (208) were divided into two populations: diabetics (72) and non-diabetics (136).We compared 66 patients with a myocardial scintigraphy with results of angiographic indexes. On angiographic images we evaluated, on the th…
Effects of Essential Hypertension on coronary Microcirculation: Focus on a Population of Hypertensives Affected by Microvascular Angina
A correlation between essential hypertension and the establishmentof myocardial ischemia is nowadays universally accepted. Coronary atherosclerosis is deemed to be the most important process through which the capability of coronary district to supply a blood flow consistent with myocardial needs can be impaired, until the onset of an anginal syndrome. In this study, we verified whether hypertensives’ coronaries, seen by performing an angiographic study, are properly definable as normal, even in presence of an overt exertional angina, or if they should rather be barely defined as “macroscopically unharmed”, through the clues of a microvascular alteration
