3. INTRODUCTION

4. • STEMI is a life threatening manifestation of CAD requiring timely
reperfusion
• incidence of STEMI is higher in the Indian population when compared
to developed countries
• Current recommendations maintain PCI as the treatment of choice ,
contingent upon rapid initiation of treatment at centers with a skilled
PCI laboratory within suggested timelines
• unavailability of primary PCI capable hospitals across India and
delays in transport -<10% of patients with STEMI-PCI in India

5. • patients who do reach the hospital early still have to deal with other issues, such
as arranging for finances, as most Indian patients pay out-of
pocket
• introduction of fibrin-specific lytic agents like tenecteplase (TNK) has improved
the IRA patency rates significantly.
• Rapid fibrinolytic treatment improved the outcomes in patients treated within
an hour of symptom onset, with tapering benefits after 3 hrs
• fibrinolysis -high rates of reocclusion of IRA
• initial bolus lysis followed by early CAG within 3–24 h
of fibrinolysis, with an appropriate PCI ='pharmacoinvasive strategy-good
alternative especially in a developing country such as India.

17. Comparison of primary angioplasty and pre-
hospital fibrinolysis in acute myocardial
infarction (CAPTIM) trial: a 5-year follow-up
• primary angioplasty (n = 421)VS pre-hospital fibrinolysis (rt-PA) with
immediate transfer to a centre with interventional facilities (n = 419)
all-cause mortality at 5 years
• 9.7% in the pre-hospital fibrinolysis group
• 12.6% in PPCI [ P = 0.18].
patients included within 2 h, 5 year mortality
• 5.8% in the pre-hospital fibrinolysis group
• 11.1% in PPCI [HR 0.50 ( P = 0.04],
Patients included after 2 h, 5 year mortality
• 14.5 vs 14.4% [ P = 0.92].

18. PRESENT STUDY
• prospective, observational, multicenter pilot study,
• between August 2011 and May 2013
• Study sites, which were capable of performing 24/7 primary
PCI, were selected from Tamilnadu,Karnataka , and Kerala
• 200 patients
• observational study, the treatment options were chosen entirely by
the patient and the attendants
• some patients who presented outside the recommended timelines
for thrombolysis have received lytic therapy .

19. AIM
• assess the safety, efficacy, and
feasibility of a pharmacoinvasive strategy in comparison to
primary PCI in STEMI

20. • primary endpoint
• set at 30 days
• composite of death, cardiogenic shock, reinfarction, repeat
revascularization, and congestive heart failure, and extended to 2
years
• Safety end points are bleeding assessed using the
TIMI classification at 30 day

21. • Baseline characteristics were no different between both groups,
except more patients in arm B were in killip's class I.
• 6.7% (n = 3) patients in arm A had insignificant disease; hence no
intervention was performed for them
• 100% of patients in arm B required angioplasty and stent
implantation.
pharmacoinvasive arm
(arm 'A') -
45 patients
PPCI arm (arm 'B') 155 patients

25. • Patients in arm A also had better TIMI flow at CAG (TIMI 3 flow in
27.9%), higher radial procedures (76.7%), more IRA patency
(82.2%), and less thrombus burden.
• In arm 'A', 12.1% -failed thrombolysis.

26. bleeding outcomes
• 2.2% vs. 2.6%, 'p' not significant).
• efficacy end points are studied at 30 days, 3 months, 6 months, 1 year, and 2
years-no difference
• There is trend of benefit for arm B in the initial few months
• Primary endpoint at 30 days -trend toward benefit in the primary PCI group
(11.1% vs.3.9%, p = 0.07, RR = 2.8).
• At the end of 2-year follow-up, the initial benefit from PPCI seems to be
narrowed as more events have occurred in PPCI group (A-17.8% vs. B-13.6%, p =
0.47, RR = 1.31;).
• The additions of events in the primary endpoint of PPCI group are mainly due to
death and repeat revascularization

27. • This may be partly due to the fact that 6.7%of patients in arm A did
not require a stent placement due to insignificant disease at the
angiogram, which means they are at no risk of stent thrombosis or
restenosis.
• non-urgent basis on which the angioplasty was performed in arm A
may also have influenced the primary endpoint over a period of
time, but this fact needs further large studies to provide
comprehensive evidence.
•

28. CONCLUSION
• fibrinolysis followed by an early coronary angiogram within 3–24 h
with PCI, if appropriate, resulted in similar outcomes when
compared to primary PCI in patients with STEMI at 2-year
follow-up.
• These findings lend further support to the adoption
of a pharmacoinvasive strategy where patient and system related
delays are inherent
