Why are acute ischemic stroke patients not receiving IV tPA?

As described in table 1, the most common documented reasons for not treating with tPA were mild or rapidly improving symptoms (51%); advanced age (7%); patient or family refusal (6%); CT findings of major infarct signs, intracerebral hemorrhage, or subarachnoid hemorrhage (6%); and platelets <100,000, partial …

Does tPA work for stroke?

TPA was the first and is still the only medicine approved by the U.S. Food and Drug Administration for treating strokes caused by clots that block blood flow to the brain.

What percentage of stroke patients get tPA?

Studies conducted in stroke registries and regional settings have found that only approximately 15% to 32% of patients presenting with ischemic stroke arrive within 3 hours of symptom onset, and of these, only about 40% to 50% are eligible for tPA clinically.

Why is TPA bad?

TPA treatment has risks. There is approximately a 3% chance of symptomatic bleeding (symptomotic hemorrhage) into the brain (because TPA thins the blood) compared to 0.2% if TPA is not given. If bleeding into the brain happens after TPA is given, it may cause your stroke symptoms to be worse and may result in death.

Can you take aspirin and ticagrelor for stroke?

Further trials including THALES (Acute Stroke or Transient Ischemic Attack Treated With Ticagrelor and Aspirin for Prevention of Stroke and Death) are ongoing and compare aspirin plus ticagrelor versus aspirin monotherapy.

Which is better for stroke aspirin or warfarin?

Strokes are a frequent complication of atrial fibrillation, and aspirin is ineffective compared to anticoagulation in reducing risk. 7 The ACTIVE W (Atrial fibrillation Clopidogrel Trial with Irbesartan for Prevention of Vascular Events) compared DAPT to warfarin.

Which is better for stroke aspirin or DAPT?

Use of DAPT is more controversial and only recently found effective in selective circumstances after ischemic stroke. DAPT with aspirin and clopidogrel was found effective in coronary artery disease but initial studies of chronic DAPT in stroke showed no additional benefit and increased bleeding over single antiplatelets.
