These studies indicate that the only independent factor for silent ischemia is advanced age.
And people with silent ischemia-- which, translated into English, means they don't have any symptoms-- it takes even longer for them to get to the hospital.
Who utilized myocardial perfusion scintigraphy for detecting silent ischemia in asymptomatic diabetic patients.
And people with silent ischemia-- which, translated into English, means they don't have any symptoms-- it takes even longer for them to get to the hospital.
During the transoperative recording, 90% of the episodes of silent ischemia occurred at frequencies below 80 bpm Figure 1.
In May 2004, he was submitted to exercise testing due to fatigue complaints.The exam revealed ST segment changes that were interpreted as silent ischemia.
A potential limitation of this study was our failure to diagnose silent ischemia prior to AMI, as a possible equivalent of preinfarction angina.
In our study we analyzed coronary angiographies of patients with recurrence of symptoms or positive test for myocardial ischemia, which reduces the cases of silent ischemia.
Of the six patients who had silent ischemia preoperatively, only two of them repeated the episodes during the recording of the day of surgery.
Most of the episodes occurred in the absence of symptoms,thus characterizing the diagnosis of silent ischemia, a result that is consistent with other studies.
Furthermore, de may be a powerful marker of silent ischemia or atherosclerosis and thus is suggested as an atypical signal dac or as an equivalent risk for the disease.
The cases of myocardial ischemia without pain, the so-called asymptomatic or silent ischemia, it is more frequent in elderly patient.
Therefore, the pressure load per se did not interfere with the occurrence of episodes of myocardial ischemia in our sample,thus suggesting that other mechanisms should participate in the genesis of silent ischemia.
Ambulatory ECG Holter monitoring might have detected silent ischemia, but it was not possible to select patients prior to AMI, making this procedure impracticable.
In patients with diabetes,the CAC score helps identify the individuals most at risk, who could benefit from screening for silent ischemia and from more aggressive clinical treatment.
Several international guidelines have shown that screening for silent ischemia is not warranted in patients with diabetes and a CAC score< 100, although it is recommended in those with a CAC score> 400 18.
The present issue of Radiologia Brasileira includes a study developed by Oki et al. who utilized myocardial perfusion scintigraphy for detecting silent ischemia in asymptomatic diabetic patients.
The acute coronary syndromes(acs) cover a spectrum of diseases,which include the silent ischemia, unstable angina and acute myocardial infarction(ami) with or without st-segment elevation.
In addition, they were followed up for a very short period of time and we had no information on how they evolved in the following months,so we cannot affirm that the findings of silent ischemia in these cases have prognostic value.
Inclusion criteria included: evidence of myocardial ischemia, stable or unstable angina, silent ischemia or a positive functional study, or a reversible change in the ECG consistent with ischaemia.
All patients that had symptomatic or silent ischemia, shown by ST-segment depression on 24-hour holter monitoring, experienced the same symptoms during exercise stress test, demonstrating the excellent negative predictive value of this propedeutic method.
Nevertheless, various studies have demonstrated that death rates by myocardial infarction andsevere CAD are the same in patients with silent ischemia and those with symptomatic ischemia. .
In such study, the authors could demonstrate that one in every five asymptomatic diabetic patients may present silent ischemia associated with age above 60 years, peripheral neuropathy, nephropathy, retinopathy and positive stress electrocardiography test for ischemia. .
Diabetes leads to autonomic neuropathy, thereby disrupting a major component of cardiovascular regulation and contributing to an increased incidence of cardiovascular diseases in diabetic patients, such as heart attack,sudden cardiac death, and silent ischemia.
Deedwania and Nelson evaluated 25 patients receiving medication and with proven silent ischemia for 24 hours with simultaneous electrocardiography and blood pressure monitoring and concluded that increases in SBP, HR and DP precede the ischemic event, reaching a peak at the moment of ischemia. .
Despite the higher cardiovascular risk and higher prevalence of ischemia on functional tests,there is no evidence so far that routine screening for silent ischemia reduces mortality in this group of patients.
In this protocol, the Holter monitoring of male patients aged 65 years or older, with no cardiovascular symptoms and with normal electrocardiogram, revealed different types of cardiac arrhythmias, from rare to frequent,as well as episodes of silent ischemia.
According to the literature, other mechanisms than changes in ventricular electrical systole might be involved in the origin of ventricular arrhythmias during hemodialysis,such as ischemic heart disease silent ischemia and electrolytic changes, and might also influence ventricular electrical systole.
In contrast, in the follow-up of asymptomatic patients, although studies have demonstrated the ability of the MPS to predict future events, 6 the guidelines do not recommend ordering routine functional tests in a period of less than 2 years, with their performance being acceptable only within this interval in specific subgroups,such as those undergoing incomplete revascularization or with prior silent ischemia, in whom a new approach is feasible.2, 5.
In a general analysis, the results obtained in the current investigation, without similar results reported in the literature,indicate a disorder of the myocardial contraction synchronism is another factor of silent ischemia induced by exercise stress, efficiently treated using diltiazem calcium inhibitor.
