How long do coronary stents last?

Timu ya uhariri ya Medcasts

Modern drug-eluting stents (DES) have very low restenosis rates — 5–10% at 1 year, with rates dropping further over time. Newer-generation stents (Synergy, Xience, Promus) outperform older ones on both restenosis and stent thrombosis.

What matters more than 'how long' is medication adherence. Dual antiplatelet therapy (aspirin + a P2Y12 inhibitor like clopidogrel or ticagrelor) is required for at least 6 months, often 12 months, sometimes longer. Stopping early — including for surgery — has caused fatal stent thrombosis events.

If you're considering elective surgery within 6–12 months of stenting, coordinate with your cardiologist. Many surgeries can wait; some can proceed with bridging strategies.

Mbinu na viwango vya uhariri

Majibu yanaandikwa na timu ya uhariri ya Medcasts na kusasishwa bei, miongozo au sheria za viza zinapobadilika.

  1. Taarifa za hospitali. Ithibati, leseni na vifaa vinakaguliwa kwenye rejista za umma (JCI, NABH, orodha za leseni za wizara za afya) na nyaraka za hospitali, na kukaguliwa upya mara kwa mara.
  2. Sifa za madaktari. Elimu na utaalamu vinatoka kwenye wasifu wa daktari hospitalini na rejista za mabaraza ya madaktari ya kitaifa.
  3. Bei. Viwango vya bei vinatoka kwenye makadirio na vifurushi vya maandishi vya hospitali, si bei za matangazo.
  4. Maandishi ya kitabibu. Yanaandikwa na timu yetu ya uhariri na kukaguliwa dhidi ya miongozo ya sasa kabla ya kuchapishwa.
  5. Uhuru. Hospitali haziwezi kulipa ili kubadilisha nafasi yao kwenye kurasa zetu.
