Highlighted as a Late-Breaking Clinical Trial on April 4

— One-Year Data on the ABSORB(TM) Bioresorbable Vascular Scaffold to be

Abbott (NYSE: ABT) today announced the company's schedule of key data
presentations at the American College of Cardiology's (ACC) 60th Annual
Scientific Session and i2 Summit 2011, to be held April 2 - 5 in New Orleans.
Highlights include late-breaking two-year data from EVEREST II, the trial of
the investigational MitraClip(R) system, which is a first-of-its-kind,
catheter-based device for mitral valve repair. In addition, data for the
ABSORB(TM) bioresorbable vascular scaffold (BVS) will be presented as an
Interventional Featured Clinical Trial and the XIENCE V(R) Everolimus Eluting
Coronary Stent System will be featured in a pooled analysis of two-year data
from the SPIRIT II, III, IV and COMPARE trials.

"Over the course of this year, Abbott will continue to strengthen its
vascular leadership with a number of milestones across key areas of our
business, including important data that will be presented at ACC for our
MitraClip system, ABSORB bioresorbable vascular scaffold and market-leading
XIENCE V stent," said Robert Hance, senior vice president, vascular, Abbott.
"Anchored by our comprehensive portfolio of on-market vascular devices and an
industry-leading vascular pipeline, we continue to generate promising
advancements in our coronary, endovascular and structural heart technologies
- all of which have the potential to make a significant impact on patient
care."

Key presentations are as follows (all times are Central):

EVEREST II: Two-year results on the MitraClip system from EVEREST II will
be presented by Ted Feldman, M.D., FSCAI, director, Cardiac Catheterization
Laboratory, and The Mr. and Mrs. Charles R. Walgreen Chair in Interventional
Cardiology, NorthShore University HealthSystem, Evanston, Ill. The data will
be presented during the late-breaking clinical trials session on Monday,
April 4, at 8 a.m. in the Joint Main Tent: La Nouvelle of the Ernest N.
Morial Convention Center. The MitraClip system received CE Mark in 2008. In
the U.S., the MitraClip system is limited to investigational use only and is
not available for sale. The MitraClip system is currently under review for
approval by the U.S. Food and Drug Administration.

ABSORB: One-year data on 101 patients from the second phase of the ABSORB
trial, evaluating Abbott's ABSORB BVS, will be presented as an Interventional
Featured Clinical Trial on Sunday, April 3, at 6 p.m. in room 354 and 355 of
the Ernest N. Morial Convention Center. The ABSORB BVS restores blood flow by
opening a clogged vessel and then is slowly metabolized and resorbed by the
body. In January 2011, Abbott announced that it received CE Mark approval in
Europe for ABSORB, the world's first drug eluting BVS for the treatment of
coronary artery disease. ABSORB is not currently available for sale in the
U.S.

SPIRIT II, III, IV and COMPARE: Two-year pooled results from the SPIRIT
II, III, IV and COMPARE trials will be presented on Sunday, April 3, at 8
a.m. in room 353 of the Ernest N. Morial Convention Center. The analysis from
these four trials will examine predictors of artery re-blockage, cardiac
death or heart attack out to two years in nearly 7,000 patients, including
patients with complex disease, following treatment with XIENCE V or a
TAXUS(R) paclitaxel-eluting stent.

About XIENCE V

Abbott's XIENCE V drug eluting stent is marketed in the United States,
Europe, Japan and other international markets.

Everolimus, developed by Novartis Pharma AG, is a proliferation signal
inhibitor, or mTOR inhibitor, licensed to Abbott by Novartis for use on its
drug eluting stents. Everolimus has been shown to inhibit in-stent neointimal
growth in the coronary vessels following stent implantation, due to its
anti-proliferative properties.

XIENCE V is indicated for improving coronary luminal diameter in patients
with symptomatic heart disease due to de novo native coronary artery lesions
(lesions less than or equal to 28 mm) with reference vessel diameters of 2.5
mm to 4.25 mm. Additional information about XIENCE V, including important
safety information, is available online at www.xiencev.com or
