What causes reinfarction?

What causes reinfarction?

The most common cause of reinfarction after primary percutaneous coronary intervention is stent thrombosis, with the first 30 days being the greatest risk period. Reinfarction confers a ≈8-fold increased 3-year risk of cardiac mortality.

How long after a myocardial infarction is the risk for reinfarction the greatest?

As shown in Figure 1, the greatest risk of first reinfarction was within 30 days after PCI (≈1.8% of patients), with a steady increase thereafter through 3 years. after primary percutaneous coronary interven- tion in ST-segment–elevation myocardial infarction.

What is myocardial reinfarction?

Recurrent MI or reinfarction is defined as recurrence of clinical signs and symptoms of ischemia in patients with previously diagnosed MI, with accompanying electrocardiographic changes and raised serum biomarker levels consistent with myocardial necrosis [1].

What are the risks of PCI?

Complications can include:

  • Injury to the heart arteries, including tears or rupture.
  • Infection, bleeding, or bruising at the catheter site.
  • Allergic reaction to the dye or contrast used.
  • Kidney damage from the dye or contrast.
  • Blood clots that can lead to stroke or heart attack.

How is reinfarction diagnosed?

The term “reinfarction” is used for an acute MI that occurs within 28 d of a MI. If the cTn concentration is elevated, but stable or decreasing at the time of suspected reinfarction, the diagnosis of reinfarction requires a 20% or greater increase in the cTn measurement.

What is the best way to prevent reinfarction?

The clinical trials for prevention of reinfarction showed that the correction of risk factors and the use of anticoagulation and/or antiaggregation therapy, beta-blockers or Ca(++)-antagonist drugs, must be chosen in relation to the myocardial damage related to previous infarct.

What are the side effects after angioplasty?

The risks associated with angioplasty and stents include:

  • allergic reactions to medication or dye.
  • breathing problems.
  • bleeding.
  • blood clots.
  • infection.
  • kidney damage.
  • re-narrowing of your artery, or restenosis.
  • rupture of your artery.

How long is troponin elevated after MI?

Most patients who have had a heart attack have increased troponin levels within 6 hours. After 12 hours, almost everyone who has had a heart attack will have raised levels. Troponin levels may remain high for 1 to 2 weeks after a heart attack.

Which combination of medications are prescribed to the patient post MI to decrease the risk of a second MI?

Clopidogrel and ticagrelor are recommended for conservative medical management of MI in combination with aspirin (162 to 325 mg per day) for up to 12 months. Early administration of beta blockers is recommended during hospitalization after an MI.
