“…Estos datos son corroborados por otros autores 23,[26][27][28][29] . Las variables independientes asociadas a eventos cardiacos fueron: edad, cirugía de emergencia, insuficiencia cardiaca clase funcional mayor o igual a 2 (IC ≥ 2), sobrecarga ventricular izquierda (SVE), revascularización del miocardio y extrasistolia ventricular, pero el tabaquismo no estuvo asociado de forma independiente.…”

“…Como se puede notar, cuanto mayor sea el número de sistemas agredidos en el preoperatorio, mayor será la probabilidad de muerte. Muchas de las variables descritas (edad, IC ≥ 2, SVE, alteraciones en los parámetros de laboratorio y cirugía de emergencia) se asocian a eventos cardiovasculares perioperatorios 21,31,[26][27][28][29] , que se asocian a la mortalidad. El antecedente de hepatopatía se relacionó a la mortalidad probablemente por aumentar las chances de infección, sepsis 33 e insuficiencia renal aguda 34 perioperatoria.…”

“…Los eventos cardiacos postoperatorios estudiados fueron infarto de miocardio 25,27 , angina inestable 28 , edema pulmonar y arritmias con inestabilidad hemodinámica. Esta última fue definida por la presencia de taquicardia o fibrilación ventricular o taquicardia supraventricular asociada a disnea, presión arterial sistólica < 90 mmHg o angina.…”

“…8 Cardiac events included cardiac death, non-fatal myocardial infarction, unstable angina and congestive heart failure defined as follows. 9,11 Cardiac death was defined as death as a result of myocardial infarction, heart failure or arrhythmias. The diagnostic criteria for myocardial infarction were based on changes in ECG and the serum creatine kinase value: new ECG Q-wave ≥1 mm or creatine kinase myocardial-bound ≥5% or both.…”

ardiac risk should be stratified in individual patients who are to undergo surgery, but it is difficult to assess the likelihood of perioperative cardiac events mainly because of complicated interrelationships between clinical risk factors and type of surgery. To overcome this problem, The American College of Cardiology/American Heart Association (ACC/AHA) Task Force published guidelines for perioperative cardiovascular evaluation for noncardiac surgery in 1996 and 2002. 1,2 MethodsThis retrospective cohort study examined data collected from patients referred for preoperative stress myocardial perfusion SPECT before non-cardiac surgery. Written informed consent was obtained from all patients concerning the examination protocol, possible side-effects and the use of SPECT data for research purposes. The form to obtain consent was approved by the institutional committee. Patient PopulationOur database for preoperative risk stratification with myocardial perfusion SPECT was used to identify 2,402 consecutive patients who underwent preoperative dipyridamole stress SPECT between January 1997 and October 2005. All 1,339 patients in the database meeting the following criteria were selected to participate in the current study: scheduled non-cardiac surgery of intermediate or low risk, and having intermediate or minor clinical risk factors. The classifications of operation risk and clinical risk factors were based on the ACC/AHA Guidelines. 1,2 Operation was cancelled or deferred after SPECT imaging in 119 patients, and 1,220 patients underwent surgery. The types of surgery and clinical risk of the 1,220 patients are indicated in Table 1 and demoCirc J 2007; 71: 1395 -1400 (Received January 15, 2007 revised manuscript received June 5, 2007; accepted June 6, 2007 1395 -1400)

“…[1][2][3][4][5][6][7][8][9] Preoperative myocardial perfusion imaging is useful for further stratification of the risk in moderate-and highrisk patients 3,4 because the redistribution findings can be used as predictive factors for cardiac events, and the technique has a high negative predictive value.

valuating the risk of perioperative cardiac events related to noncardiac surgery is important. [1][2][3][4][5][6][7][8][9] Preoperative myocardial perfusion imaging is useful for further stratification of the risk in moderate-and highrisk patients 3,4 because the redistribution findings can be used as predictive factors for cardiac events, and the technique has a high negative predictive value. [5][6][7][8] Moreover, recent studies suggest that the likelihood of cardiac events increases with the severity of the defect score on images evaluated semi-quantitatively 4,6-9 and guidelines for the perioperative cardiovascular evaluation of noncardiac surgery patients were recently published by the ACC/AHA, providing a framework for weighting the cardiac risk of noncardiac surgery based on patients' risk profiles and the type of operation. 10 Of the procedures, aortic surgery is claimed to be high-risk (the reported cardiac risk is often ≥5%), not only because it is highly invasiveness surgery but also because of the high prevalence of coronary artery disease in patients with aortic diseases. 10-12 However, there are few studies regarding preoperative risk stratification in Japanese patients who undergo aortic surgery. 13,14 Thus, the present study evaluated whether perioperative cardiac events related to aortic surgery can be predicted by preoperative pharmacologic stress myocardial perfusion imaging. Methods SubjectsThe subjects of this study were 302 consecutive patients who underwent elective aortic surgery after pharmacologic stress single-photon emission computed tomography (SPECT) between January 1998 and August 2003. SPECT study was performed in all patients unless contraindications such as bronchial asthma and advanced heart block were present. There were 261 men and 41 women, aged 71±10 years (35-86 years); 128 of them (42%) were aged 75 years or older. Medical history of angina pectoris was noted in 19 patients, myocardial infarction (MI) in 26, and heart failure in 5; 19 of them had undergone coronary revascularization. Hypertension was found in 217 patients, hypercholesterolemia in 73, diabetes mellitus (DM) in 55, and renal insufficiency defined as serum creatinine level ≥2.0 mg/dl in 20.The etiologies of the aortic diseases were type B aortic dissection in 56 patients, thoracic aortic aneurysm in 124, and abdominal aortic aneurysm in 122. The indication for aortic surgery was decided by cardiovascular surgeons based on the anatomical and pathological indications. [15][16][17][18] The type of surgery was conventional open surgery in 75 patients and endovascular surgery with stent -graft placement in 227. Aortic surgery including stent -graft placement was performed under general anesthesia. Approval to perform the endovascular surgery was obtained from the Ethical Committee of Tokyo Medical University. Written informed consent was obtained from all of the patients. Stress Myocardial ScintigraphyPharmacologic stress SPECT was performed ≥15 h after Background Aortic surgery is an invasive, high-risk noncard...
