What does it mean when you think about a stroke?
A stroke – if you think about it as interruption of blood flow to the brain, either there isn't enough blood flow getting to the brain or there's too much.
How long does it take for a stroke to be treated with IV thrombolysis?
As is the case for most relative contraindications, the potential risks and benefits of IV thrombolysis in this subset of patients most likely varies considerably according to several factors. Twenty-one days has been arbitrarily chosen and in some cases may be unnecessarily cautious. Factors to consider include the time elapsed since hemorrhage, the severity of stroke deficits, the cause and severity of the hemorrhage, and what treatments were provided for the prior bleeding episode. Patients with severe stroke deficits who have had occult GI/GU hemorrhages or diffuse or multifocal lesions susceptible to bleeding may be safer candidates for the consideration of intra-arterial stroke therapy, as the risk of systemic IV thrombolysis may be prohibitive in these patients.
What is the exclusion criterion for IV RTPA?
Uncontrolled hypertension to values exceeding a systolic of 185 mm Hg or diastolic of 110 mm Hg is an exclusion criterion to IV rtPA according to the 2013 AHA guidelines and the drug label. 1 This is likely derived from an exclusion criterion for the National Institute of Neurological Disorders and Stroke (NINDS) trials. 6 The relationships between blood pressure (BP), antihypertensive treatment, and clinical outcomes in acute stroke are complex. Hypertension has been associated with increased risk of poor outcomes and ICH in several studies. 7 – 9 In the Safe Implementation of Treatments in Stroke (SITS) registry, higher systolic BP (SBP) after lysis was independently associated with worse outcomes and an increased risk of ICH. 7 The association between SBP and sICH was linear, while the association between SBP and clinical outcome was U-shaped. In a post hoc analysis of the NINDS trial, antihypertensive therapy given before thrombolysis was not associated with differences in outcomes. However, patients with hypertension who received antihypertensives after randomization were less likely to have a favorable outcome at 3 months. 10
What is an arterial puncture?
Arterial puncture of a noncompressible vessel within 7 days preceding acute stroke symptoms is a warning on the Activase (alteplase, rtPA) insert and is a relative contraindication to administering IV rtPA according to AHA guidelines. 1 This scenario is extremely rare and would most likely occur in critically ill patients who had recent catheterization of the subclavian or internal jugular veins. Other situations in which noncompressible veins are accessed are during placement of pacing or defibrillation leads, dialysis catheters, pulmonary artery catheters, or transcatheter heart valve placements. A patient undergoing one of these procedures may be less functional and more ill than the general population in which IV rtPA has been studied, and the ratio of risks to potential benefits in this subgroup may be substantially different as well. The common clinical observation of increased bleeding in anticoagulated patients who have central venous catheters placed and the potential consequence of uncontrollable and life-threatening hemorrhage likely justify this exclusion criterion, although there is no existing data in the published literature to support or oppose this recommendation.
What is the determinant of stroke outcome?
Initial severity of deficits is the main determinant of stroke outcome regardless of whether thrombolysis is administered. Severe strokes (variably defined as NIHSS >20 or >25) are typically caused by large infarctions, which may have a higher risk of hemorrhagic transformation. This is reflected in the FDA package insert for Activase (alteplase, rtPA) warning that the risks of ICH are higher in patients with severe stroke. However, there is solid evidence that IV thrombolysis is beneficial to patients with severe strokes and in fact these patients may derive the greatest benefit from the treatment.
How long after MI should I be on IV thrombolysis?
Based on this, it has been suggested that the time after MI to be considered a contraindication for IV thrombolysis should be shortened to 7 weeks. 85 The type of MI, in addition to the severity of stroke symptoms, should also factor in the decision-making process. Patients with non-STEMI, particularly those that do not involve the anterior cardiac wall, may be at lower risk of this complication, but there are no solid data to estimate risks or guide treatment in this subset of patients.
What is the blood glucose level for IV RTPA?
Measurement of blood glucose is a necessary requisite before the administration of IV rtPA. The main reason for this condition is exclusion of severe hypoglycemia, which can infrequently mimic stroke symptoms. Even more rarely, severe hyperglycemia can also produce focal neurological deficits. Previous versions of the AHA guideline for acute stroke treatment listed glucose levels below 50 mg/dL (2.7 mmol/L) and above 400 mg/dL (22.2 mmol/L) as contraindications for thrombolysis, but the most recent edition only keeps hypoglycemia as an exclusion. 1 Meanwhile, the Food and Drug Adminitration (FDA) package insert for Activase (alteplase, rtPA) recommends “special diligence” in making the diagnosis of stroke in patients whose glucose levels are <50 or >400 mg/dL.
How many patients were in the third stroke trial?
The third international stroke trial (IST-3), an international randomized controlled trial included 1617 patients older than the age of 80 years. 57 Patients were randomized to rtPA or placebo within 6 hours of symptom onset. The primary end point was the proportion of patients alive and independent at 6 months, which was not significantly different between the 2 groups (37% of the rtPA group and 35% of the control group [ P = .181]). In a subgroup analysis, a significant difference existed in the adjusted effect of treatment between patients >80 years and those younger, suggesting a greater benefit in the very elderly patients. In addition, a systematic review analyzing 7012 patients from 12 trials showed that patients older than80 years of age benefited similar to those younger, especially when treatment was initiated early.
