Ischemia with no obstructive coronary arteries (INOCA) is an increasingly recognized condition in patients presenting with angina and positive stress tests but without significant coronary artery stenosis. The paper discusses a potential interference between vasodilators used in trans-radial access and coronary spasm testing.
Ischemia with nonobstructive coronary arteries (INOCA) has high morbidity, mortality, and poor quality of life. Metabolic syndrome (MetS) is a complex of multiple cardiac metabolic riskfactors, significantly.
This EKG is diagnostic of transmural ischemia of the inferior wall. If it is angina, lowering the BP with IV Nitroglycerine may completely alleviate the pain and the (unseen) ECG ischemia. Transmural ischemia (as seen with the OMI findings on ECG) is not very common with demand ischemia, but is possible. Smith SW. .
In this phenomenon, a thrombus forms within the lumen of the stent graft component of the frozen elephant trunk prosthesis and puts the patient at risk for downstream embolization with visceral or lower limb ischemia.
Objective:Forward head posturing (FHP) has been associated with chronic anatomic vertebral artery disturbances possibly leading to posterior circulation ischemia. The data supporting FHP as a true riskfactor of posterior circulation stroke has not been well established.
The CAD Staging System is a noninvasive imaging-based investigational software device that analyzes important and actionable features of coronary atherosclerosis, stenosis and ischemia.
I quickly reviewed the patient’s records and saw that she was a 53 year old woman with a history of BMI 40, but no other identifiable riskfactors for coronary artery disease. This proves effective treatment of the recurrent ischemia. The patient had no further symptoms of ischemia. I performed bedside echocardiography.
Peripheral artery disease (PAD) continues to increase in prevalence worldwide due to riskfactors such as advanced age, diabetes mellitus, and obesity. Critical limb ischemia (CLTI) is the advanced form of PAD that can result in a lack of healing and limb loss as the most devastating consequence.
Precordial ST depression may be subendocardial ischemia or posterior STEMI. I have warned in the past that one must think of other etiologies of ischemia when there is tachycardia. Whether it is subendocardial ischemia or posterior STEMI, if you cannot get it to resolve, you must activate the cath lab. There is no ST elevation.
Given the consistency of the clinical profile with typical angina, associated riskfactors, and abnormal ECG findings, a cardiology consult was promptly requested. It should be known that each category can easily manifest the generic subendocardial ischemia pattern. What’s interesting is that the ECG can only detect ischemia.
A 39 yo otherwise healthy man with no riskfactors was walking at the mall when he developed chest pressure. Thus, there are some suspicious abnormalities, but no definite signs of ischemia. The difference is significant and highly suggests posterior ischemia. He was diaphoretic. It is very subtle but real.
He had some cardiac riskfactors including hypertension, on meds, but no previous coronary disease. There is about 1 mm of STE in aVR I con sidered but rejected subendocardial ischemia. Is it subendocardial ischemia, or inferior MI? A male in his 60's called 911 for chest pain. Here is his prehospital ECG: Diagnosis?
By Magnus Nossen This ECG is from a young man with no riskfactors for CAD, he presented with chest pain. young male no riskfactors and ST-elevation in several leads) As Dr. Smith has emphasized many times you diagnose pericarditis at your patient's and your own peril. How would you assess this ECG?
Hyperhomocysteinemia (Hhcy), a metabolic disorder is recognized as a riskfactor for ischemic stroke. Cerebral ischemia was induced by middle cerebral artery occlusion (60 min) in control and Hhcy rats. Stroke, Volume 55, Issue Suppl_1 , Page AWP322-AWP322, February 1, 2024.
5 ICSS‐ MRI study (International Carotid Stenting Study Magnetic Resonance Imaging Study), indicated that patients with periprocedural hemodynamic depression had decreased cerebral blood flow and increased the risk of new lesions in imaging.6 This is secondary to delayed postoperative cerebral ischemia and infarction caused by vasospasm.7
Background:Myocardial infarction with nonobstructive coronary artery disease (MINOCA) is a special syndrome with clear evidence of myocardial ischemia, but no clear stenosis of coronary artery imaging sign. Circulation, Volume 150, Issue Suppl_1 , Page A4143007-A4143007, November 12, 2024.
Introduction:Elevated Low-Density-Lipoprotein Cholesterol (LDL-C) blood levels are a riskfactor for atherosclerosis. Lipid-lowering therapies mitigate the risk of atherothrombotic events. Stroke, Volume 56, Issue Suppl_1 , Page ATP318-ATP318, February 1, 2025. were asymptomatic and 40.2% acute symptomatic.
This suggests further severe ischemia. There is 1 mm of ST segment elevation in lead aVR — which in the context of ST segment flattening in most other leads, suggests that there may be a component of subendocardial ischemia from underlying coronary disease. Detailed coronary artery evaluation not performed. Downstream vasospasm?
These ischemic lesions are associated with poor ICH outcomes, but riskfactors for their formation are unknown. Further work is needed to address the generalizability of our data and to clarify relationships of platelet unit characteristics, cerebral ischemia, and clinical outcomes after ICH. 217.94, p = 0.03).Conclusions:Major
In CRAO, the time between initial insult to presentation is significant because, analogous to ischemic stroke, the duration of ischemia is inversely related to viable retinal tissue. This article provides a narrative review of pathophysiological features, riskfactors, and current and emerging management techniques of CRAO.
Distilling this case into its most salient components, a man with multiple riskfactors for coronary disease is presenting with several days of chest pain and markedly elevated troponin with no other reason to explain the lab abnormality ( e.g. sepsis). High sensitivity troponin I (hsTnI) obtained around that time was 5548 ng/L (ref.
Recent studies have revealed increased plasma von Willebrand factor (VWF) levels and reduced ADAMTS13 activity (the riskfactors for stroke) in patients with RTIs, including COVID-19. However, it remains unclear whether an imbalance in the VWFADAMTS13 axis plays a causative role in the pathophysiology ofS. On day 6 (S.
Von Willebrand factor (VWF) plays a crucial role in hemostasis and thrombosis by promoting platelet adhesion to the subendothelial matrix and factor VIII stabilization. aureus-infected WT,Vwf-/-,Adamts13-/-mice were subjected to transient (30 min) middle cerebral artery ischemia using a filament model.
No riskfactors, leads a healthy lifestyle. No riskfactors, leads healthy lifestyle. After the hyperacute phase, the ST segments rise and only fall with either 1) reperfusion or 2) prolonged ischemia leading to irreversible infarction. BP 112/80, SpO2 100%. Patient appears only slightly anxious.
She had zero CAD riskfactors. Now you have ECG and troponin evidence of ischemia, AND ventricular dysrhythmia, which means this is NOT a stable ACS. It they are static, then they are not due to ischemia. This is better evidence for ischemia than any other data point. hours of substernal chest pressure.
remain hypo- or akinetic for some time even if not infarcted, just due to the profound ischemia incurred during the occlusive phase. Thus, an acute wall motion abnormality is not a sign of active or persistent ischemia, and thus is not necessarily an indication for emergent cath. Even many NOMI have wall motion abnormalities.
ET Main Tent (Hall B1) This session offers more insights from key clinical trials presented at ACC.24 24 and find out what it all means for your patients.
The patient’s angiogram should have been expedited, but the EKG change was not recognized as recurrence of transmural ischemia. Consider the scenario in today's CASE: This 56-year old man with riskfactors including diabetes and known coronary disease — presented to the ED on Day #1 with new weakness , fatigue , lethargy and confusion.
For post-stroke patients, arrhythmias represent a key riskfactor for complications and a worse prognosis. The authors of the study stated that rhythm disturbances may also lead to brain ischemia. “AF For post-stroke patients, arrhythmias represent a key riskfactor for complications and a worse prognosis.
In other words, the inferior ST segments in the first ECG show more straightening which is more concerning for ischemia. In this context, patient pain free — post-PCI and with the previous ECGs in mind— the large inferior T waves represent reciprocal change from lateral reperfusion T waves and are not hyperacute T waves of ischemia.
No thromboembolism risks, not pleuritic, no radiation to the back. No cardiac riskfactors, no cocaine use. T-wave inversion in V2 is inconsistent with early repol, and is typical of posterior ischemia. In addition, there is ST depression, diagnostic of ischemia, in V3-V6. History: Onset of CP 2.5
He had multiple cardiovascular riskfactors and the EM physician strongly suspected ACS. Ongoing ischemia (by symptoms, ECG, or troponin) despite maximal medical management is an indication for emergent cath lab activation. == MY Comment by K EN G RAUER, MD ( 8/15/2019 ): == Once again, the w rong q uestion was a sked in this case.
Syncope without prodrome is a significant riskfactor for cardiac syncope and poor outcome. These include rate-slowing medication recent ischemia/infarction hypothyroidism sleep apnea. Learning Points: 1. An AV node that is not transmitting impulses from atrial fibrillation is sick, and is the likely culprit in syncope.
RiskFactors: High Cholesterol. But ST depression is present in multiple leads, with ST elevation in lead aVR — a picture consistent with diffuse subendocardial ischemia from multi-vessel disease. So, I'm a follower of your blog, and I think I have a interesting case that I attended yesterday." Vitals Signs: Normal."
No history, meds, or riskfactors. 2) There are three causes of tall T waves; hyperkalemia, hyperacute ischemia and normal variant (Atlas of Electrocardiography by K. They gave him water with salt, as he thought he was dehydrated." When we arrived, he was alert, sweating, and felt weak. Ambulated to ambulance for eval.
A 40 something woman with a history of hyperlipidemia and additional riskfactors including a smoking history presented with substernal chest pain radiating to "both axilla" as well as the upper back. The source of this case is anonymous. She was reportedly "pacing in her room while holding her chest". TnI peaked at 67.10
He has no cardiovascular riskfactors except smoking for 10 pack-years. Ischemic ST-Segment Depression Maximal in V1-V4 (Versus V5-V6) of Any Amplitude Is Specific for Occlusion Myocardial Infarction (Versus Nonocclusive Ischemia). He says that the pain intensity was 10/10 at home but now about 4/10. His ECG is shown below.
The morphology of STE is not diagnostic of being due to acute transmural ischemia. Although this 70yo woman with cardiac riskfactors did have acute symptoms (ie, nausea, diaphoresis and syncope ) — she did not report any chest discomfort! The T-waves have significant amplitude but they are not "fat" enough to be hyperacute.
Food and Drug Administration (FDA) for its DynamX BTK System, a novel, adaptive implant for use in the treatment of narrowed or blocked vessels below-the-knee (BTK) in patients with chronic limb-threatening ischemia (CLTI). The natural history of untreated severe or critical limb ischemia. 2013;382(9901):1329-1340. J Vasc Surg.
The rate of composite outcome (in-hospital death, stroke/global ischemia, dialysis, and/or acute heart failure) was 41.2%, and 10-year mortality rate was 47.0%. These riskfactors may be valuable components for risk adjustment in the evaluation of surgical and anesthesiological strategies aiming to improve the results of surgery for TAAD.
However, as a specific subgroup of ACS, a significant proportion of patients with ACS without standard modifiable cardiovascular riskfactors (SMuRFs) are currently being identified. Background:Glycated albumin (GA) has been demonstrated to be associated with adverse outcomes in patients with acute coronary syndrome (ACS).
Implementation of a multispecialty care team approach, including expertise in riskfactor management, guideline directed medical therapies, wound and foot care and endovascular and surgical revascularization procedures, may improve outcomes for people with PAD. . - and Global Data From the American Heart Association.
Introduction:Ischemic stroke is one of the leading causes of death in the United States and is a known riskfactor for Alzheimers Disease (AD) development. Therefore, further studies are warranted to assess the interaction between ischemia and -amyloid peptide on histological injury and functional recovery.
