Written informed consentwas obtained from the patient for publication of this casereport and any accompanying images.Clinical reportAn 80 years old man, with history of hypertension andbenign prostatic hypertrophy noted chest pressure formild efforts and, some weeks later, he addressed to hisGeneral Practitioner for an appointment. After arriving tothe Community Health Department he suffered a cardiacarrest. Immediate Basic Life Support (BLS) was started,with chest compressions and bag mask ventilation, and arequest for an Advanced Life Support (ALS) team wasmade through the national emergency number (112).The initial evaluation made by the ALS team, about nineminutes after contact, confirmed the cardiac arrest in ven-tricular fibrillation. Defibrillation with 200J was per-formed (Fig. 1A) and BLS was continued.When an endotracheal tube was to be inserted, right afterdefibrillation, the patient presented masseter muscle con-traction, so BLS procedures were discontinued for reeval-uation. The rhythm was a wide QRS tachycardia withpulse (Fig. 1B) and the victim had regained spontaneousbreathing. The examination revealed blood pressure of133/62 mmHg, heart rate of 130 bpm and pulse oximetryof 97% with an inspiratory oxygen fraction of 50%. Therewas a partial regain of consciousness, with a GlasgowComa Score of 11 (eyes opening: 4, verbal response: 2,motor response: 5).Thirty minutes after the event, the patient had been trans-ferred to an emergency department. He remained hemo-dynamically stable without vasoactive support, withblood pressure of 96/50 mmHg, heart rate of 83 bpm, andpulse oximetry of 97%. Cardiopulmonary auscultationwas normal.There was a rapid improvement of the neurologic status(Glasgow Coma Score 15, with lacunar amnesia for theevent) but the patient complained of chest pain. The elec-trocardiogram showed sinus rhythm with heart rate of 75,right bundle branch block and ST segment depression inleads V4-V6 (Fig. 1C).Blood tests showed: creatine kinase (CK) 280 U/L, MBfraction 99 U/L, myoglobin 736 μg/L, cardiac troponin I0.78 μg/L and CK-MB mass 6.7 μg/L.An urgent coronary angiography revealed left main plusthree vessels coronary artery disease with an occlusion inthe middle left anterior descending (LAD) coronaryartery. (Fig. 2).The patient was referred to a cardiothoracic surgery centerand was submitted to urgent coronary artery bypass graft-ing, which was performed 18 hours after the cardiac arrest.Myocardial revascularization was obtained with four aor-tic coronary bypasses with left internal mammary artery toLAD, an inverted saphenous vein segment to diagonalbranch, and a sequential saphenous vein segment to sec-ond marginal and posterior descending arteries.During the surgery a fresh thrombus was removed fromthe proximal segment of the LAD, which was probably thecause of the ventricular fibrillation. There were no compli-cations after surgery, and the patient was discharged sevendays later.At 24-months follow-up the patient was asymptomaticand free from clinical events.DiscussionIn this case, an elderly man with undiagnosed severe cor-onary artery disease was successfully resuscitated after car-diac arrest (CA). CA is defined as cessation of cardiacmechanical activity as determined by the absence of a pal-pable central pulse, apnea, and unresponsiveness [4].Sudden CA is an important cause of death, being respon-sible for almost half a million deaths per year in theUnited States [1].Although the majority of cases of sudden death from car-diac causes involve patients with preexisting coronaryheart disease, CA is the first manifestation of this underly-ing problem in 50 percent of patients [2].The overall rate of successful resuscitation in patients without-of-hospital CA has been poor, averaging 2 to 23 per-cent in different reports [1-3].About half patients with out-of-hospital CA are found inventricular fibrillation or pulseless ventricular tachycardia[5]. In this subgroup of patients, when successfully resus-citated, between 21 and 34 percent were discharged alivefrom the hospital. One-year survival rates varied between16 and 30 percent [2,3,6].By far, the most important factor for success in resuscita-tion is time to treatment, in particular, defibrillation [2,4-8]. Obviously, this is also true for out-of-hospital CA, withbetter survival achieved with early defibrillation (less thanfour to eight minutes) [1,3,8], as the effectiveness of thisprocedure diminishes rapidly as time passes [9]. Eachminute that defibrillation is delayed reduces by seven toPage 2 of 5(page number not for citation purposes)Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine 2009, 17:63 http://www.sjtrem.com/content/17/1/63Page 3 of 5ten percent the chance of hospital discharge. Resuscitationefforts initiated after eight to ten minutes are usuallydoomed to fail [2,5]. On the other hand, if CA from ven-tricular tachycardia or ventricular fibrillation occurswhere there are readily available defibrillators (emergencyroom or automatic external defibrillators in out-of-hospi-tal CA) the odds of survival is above 50% [10].Other factors associated with better survival were earlyaccess to emergency medical care and early cardiopulmo-nary resuscitation [1,5-7]. BLS improves survival by delay-ing the degradation of the cardiac rhythm to asystole andin doing so enhances the possibility of successful defibril-lation on arrival of the ALS team [5].In the present report, the presence of the patient in ahealth care facility allowed the provision of BLS thatraised the chance of recovery. Although the duration ofCA has been estimated in about nine minutes, several fea-tures were identified as good outcome predictors.

The stability ofhemodynamic status without inotropic or vasoactive sup-port and the absence of hypotension, oliguria or hyperg-lycaemia were also indicative of good prognosis [11]. Theearly presence of a cough/swallow response (<30 min-utes), pupillary light reflex (<2 minutes) and a GlasgowComa Score of 10 or more (in the first 48 h) are also signsassociated with better chances of recovery [11].Following resuscitation from cardiorespiratory arrest,about 80 percent of patients remain comatose [11].Although we found no reports, we believe that in out-of-hospital CA, if ALS is not readily available, the need formechanical ventilation after return of spontaneous circu-lation is the rule. In the described case, the patient recov-ered breathing immediately after defibrillation. This wasunexpected, considering that CA lasted for about ten min-utes. Furthermore, the patient had reduced conscience(Glasgow Coma Score of 11), but he had a rapid recoveryperiod and, about thirty minutes after the episode, he hadGlasgow Coma Score of 15. There is evidence that inducedhypothermia improves outcomes in patients who arecomatose after resuscitation from out-of-hospital cardiacarrest [12,13]. With no persistent coma after return ofspontaneous circulation, no therapeutic hypothermia wasinduced in this patient.The early provision of BLS could have contributed to thisrapid recovery. Also, at the initial evaluation the patientcould be in ventricular tachycardia with low cardiac out-put (considered as CA by the first responder). This rhythmmay have degenerated in ventricular fibrillation closer intime with the arrival of the ALS team. There are docu-mented reports of similar evolutions [2].The costs-effectiveness of out-of-hospital ALS is difficultto calculate. In a report describing the costs of out-of-hos-pital CAs of cardiac origin [14], the cost per patient dis-charged alive was 40 642, with a cost of 6632 per lifeyear gained. Moreover, 4.4% of the costs were spent onpatients not surviving to hospital, 35.6% on patientsdying in the hospital while 60% of the total costs werespent on patients discharged from hospital alive [14].ConclusionThis case illustrates the possibility of long-term survivalwithout neurological sequelae after an episode of suddenCA, in an old patient with undiagnosed severe coronaryartery disease and presumable acute coronary syndrome.Although ALS was started nine minutes after the witnessedcollapse, return of spontaneous circulation after the firstdefibrillation and prompt breathing recovery were posi-tive predictors of the success of the resuscitation maneu-vers. The fact that CA has occurred in a health care facilityallowed prompt BLS, which contributed to the recovery.Furthermore, early detection and treatment of the acutereversible cause (myocardial ischemia in this case) wascrucial for long-term prognosis.ConsentWritten informed consent was obtained from the patientfor publication of this case report and any accompanyingimages.

Abstract
An 80 years old man suffered a cardiac arrest shortly after arrival to his local health department.
Basic Life Support was started promptly and nine minutes later, on evaluation by an Advanced Life
Support team, the victim was defibrillated with a 200J shock. When orotracheal intubation was
attempted, masseter muscle contraction was noticed: on revaluation, the victim had pulse and
spontaneous breathing.
Thirty minutes later, the patient had been transferred to an emergency department. As he
complained of chest pain, the ECG showed a ST segment depression in leads V4 to V6 and
laboratorial tests showed cardiac troponine I slightly elevated. A coronary angiography was
performed urgently: significant left main plus three vessel coronary artery disease was disclosed.
Eighteen hours after the cardiac arrest, a quadruple coronary artery bypass grafting operation was
undertaken. During surgery, a fresh thrombus was removed from the middle left anterior
descendent artery. Post-operative course was uneventful and the patient was discharged seven
days after the procedure. Twenty four months later, he remains asymptomatic.
In this case, the immediate call for the Advanced Life Support team, prompt basic life support and
the successful defibrillation, altogether, contributed for the full recovery. Furthermore, the
swiftness in the detection and treatment of the acute reversible cause (myocardial ischemia in this
case) was crucial for long-term prognosis.

We describe a case of a successful resuscitation after an
episode of sudden cardiac arrest, in an old patient with
undiagnosed severe coronary artery disease and presuma-
ble acute coronary syndrome. Written informed consent
was obtained from the patient for publication of this case
report and any accompanying images.
Clinical report
An 80 years old man, with history of hypertension and
benign prostatic hypertrophy noted chest pressure for
mild efforts and, some weeks later, he addressed to his
General Practitioner for an appointment. After arriving to
the Community Health Department he suffered a cardiac
arrest. Immediate Basic Life Support (BLS) was started,
with chest compressions and bag mask ventilation, and a
request for an Advanced Life Support (ALS) team was
made through the national emergency number (112).
The initial evaluation made by the ALS team, about nine
minutes after contact, confirmed the cardiac arrest in ven-
tricular fibrillation. Defibrillation with 200J was per-
formed (Fig. 1A) and BLS was continued.
When an endotracheal tube was to be inserted, right after
defibrillation, the patient presented masseter muscle con-
traction, so BLS procedures were discontinued for reeval-
uation. The rhythm was a wide QRS tachycardia with
pulse (Fig. 1B) and the victim had regained spontaneous
breathing. The examination revealed blood pressure of
133/62 mmHg, heart rate of 130 bpm and pulse oximetry
of 97% with an inspiratory oxygen fraction of 50%. There
was a partial regain of consciousness, with a Glasgow
Coma Score of 11 (eyes opening: 4, verbal response: 2,
motor response: 5).
Thirty minutes after the event, the patient had been trans-
ferred to an emergency department. He remained hemo-
dynamically stable without vasoactive support, with
blood pressure of 96/50 mmHg, heart rate of 83 bpm, and
pulse oximetry of 97%. Cardiopulmonary auscultation
was normal.
There was a rapid improvement of the neurologic status
(Glasgow Coma Score 15, with lacunar amnesia for the
event) but the patient complained of chest pain. The elec-
trocardiogram showed sinus rhythm with heart rate of 75,
right bundle branch block and ST segment depression in
leads V4-V6 (Fig. 1C).
Blood tests showed: creatine kinase (CK) 280 U/L, MB
fraction 99 U/L, myoglobin 736 μg/L, cardiac troponin I
0.78 μg/L and CK-MB mass 6.7 μg/L.
An urgent coronary angiography revealed left main plus
three vessels coronary artery disease with an occlusion in
the middle left anterior descending (LAD) coronary
artery. (Fig. 2).
The patient was referred to a cardiothoracic surgery center
and was submitted to urgent coronary artery bypass graft-
ing, which was performed 18 hours after the cardiac arrest.
Myocardial revascularization was obtained with four aor-
tic coronary bypasses with left internal mammary artery to
LAD, an inverted saphenous vein segment to diagonal
branch, and a sequential saphenous vein segment to sec-
ond marginal and posterior descending arteries.
During the surgery a fresh thrombus was removed from
the proximal segment of the LAD, which was probably the
cause of the ventricular fibrillation. There were no compli-
cations after surgery, and the patient was discharged seven
days later.
At 24-months follow-up the patient was asymptomatic
and free from clinical events.
Discussion
In this case, an elderly man with undiagnosed severe cor-
onary artery disease was successfully resuscitated after car-
diac arrest (CA). CA is defined as cessation of cardiac
mechanical activity as determined by the absence of a pal-
pable central pulse, apnea, and unresponsiveness [4].
Sudden CA is an important cause of death, being respon-
sible for almost half a million deaths per year in the
United States [1].
Although the majority of cases of sudden death from car-
diac causes involve patients with preexisting coronary
heart disease, CA is the first manifestation of this underly-
ing problem in 50 percent of patients [2].
The overall rate of successful resuscitation in patients with
out-of-hospital CA has been poor, averaging 2 to 23 per-
cent in different reports [1-3].
About half patients with out-of-hospital CA are found in
ventricular fibrillation or pulseless ventricular tachycardia
[5]. In this subgroup of patients, when successfully resus-
citated, between 21 and 34 percent were discharged alive
from the hospital. One-year survival rates varied between
16 and 30 percent [2,3,6].
By far, the most important factor for success in resuscita-
tion is time to treatment, in particular, defibrillation [2,4-
8]. Obviously, this is also true for out-of-hospital CA, with
better survival achieved with early defibrillation (less than
four to eight minutes) [1,3,8], as the effectiveness of this
procedure diminishes rapidly as time passes [9]. Each
minute that defibrillation is delayed reduces by seven toPage 2 of 5

ten percent the chance of hospital discharge. Resuscitation
efforts initiated after eight to ten minutes are usually
doomed to fail [2,5]. On the other hand, if CA from ven-
tricular tachycardia or ventricular fibrillation occurs
where there are readily available defibrillators (emergency
room or automatic external defibrillators in out-of-hospi-
tal CA) the odds of survival is above 50% [10].
Other factors associated with better survival were early
access to emergency medical care and early cardiopulmo-
nary resuscitation [1,5-7]. BLS improves survival by delay-
ing the degradation of the cardiac rhythm to asystole and
in doing so enhances the possibility of successful defibril-
lation on arrival of the ALS team [5].
In the present report, the presence of the patient in a
health care facility allowed the provision of BLS that
raised the chance of recovery. Although the duration of
CA has been estimated in about nine minutes, several fea-
tures were identified as good outcome predictors. Consid-

Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine  2009, 17:63 http://www.sjtrem.com/content/17/1/63ering the arrest itself, the recovery of effective spontaneous
circulation after a short period of the ALS, without adren-
aline (epinephrine), and the need of only one shock, indi-
cated a good outcome [6,11]. The stability of
hemodynamic status without inotropic or vasoactive sup-
port and the absence of hypotension, oliguria or hyperg-
lycaemia were also indicative of good prognosis [11]. The
early presence of a cough/swallow response (<30 min-
utes), pupillary light reflex (<2 minutes) and a Glasgow
Coma Score of 10 or more (in the first 48 h) are also signs
associated with better chances of recovery [11].
Following resuscitation from cardiorespiratory arrest,
about 80 percent of patients remain comatose [11].
Although we found no reports, we believe that in out-of-
hospital CA, if ALS is not readily available, the need for
mechanical ventilation after return of spontaneous circu-
lation is the rule. In the described case, the patient recov-
ered breathing immediately after defibrillation. This was
unexpected, considering that CA lasted for about ten min-
utes. Furthermore, the patient had reduced conscience
(Glasgow Coma Score of 11), but he had a rapid recovery
period and, about thirty minutes after the episode, he had
Glasgow Coma Score of 15. There is evidence that induced
hypothermia improves outcomes in patients who are
comatose after resuscitation from out-of-hospital cardiac
arrest [12,13]. With no persistent coma after return of
spontaneous circulation, no therapeutic hypothermia was
induced in this patient.
The early provision of BLS could have contributed to this
rapid recovery. Also, at the initial evaluation the patient
could be in ventricular tachycardia with low cardiac out-
put (considered as CA by the first responder). This rhythm
may have degenerated in ventricular fibrillation closer in
time with the arrival of the ALS team. There are docu-
mented reports of similar evolutions [2].
The costs-effectiveness of out-of-hospital ALS is difficult
to calculate. In a report describing the costs of out-of-hos-
pital CAs of cardiac origin [14], the cost per patient dis-
charged alive was 40 642, with a cost of 6632 per life
year gained. Moreover, 4.4% of the costs were spent on
patients not surviving to hospital, 35.6% on patients
dying in the hospital while 60% of the total costs were
spent on patients discharged from hospital alive [14].
Conclusion
This case illustrates the possibility of long-term survival
without neurological sequelae after an episode of sudden
CA, in an old patient with undiagnosed severe coronary
artery disease and presumable acute coronary syndrome.
Although ALS was started nine minutes after the witnessed
collapse, return of spontaneous circulation after the first
defibrillation and prompt breathing recovery were posi-
tive predictors of the success of the resuscitation maneu-
vers. The fact that CA has occurred in a health care facility
allowed prompt BLS, which contributed to the recovery.
Furthermore, early detection and treatment of the acute
reversible cause (myocardial ischemia in this case) was
crucial for long-term prognosis.

No fate but what we make: a case of full recovery after out-of-hospital cardiac arrest

Abstract  An 80 years old man suffered a cardiac arrest shortly after arrival to his local health department. Basic Life Support was started promptly and nine minutes later, on evaluation by an Advanced Life Support team, the victim was defibrillated with a 200J shock. When orotracheal intubation was attempted, masseter muscle contraction was noticed: on revaluation, the victim had pulse and spontaneous breathing. Thirty minutes later, the patient had been transferred to an emergency department. As he complained of chest pain, the ECG showed a ST segment depression in leads V4 to V6 and laboratorial tests showed cardiac troponine I slightly elevated. A coronary angiography was performed urgently: significant left main plus three vessel coronary artery disease was disclosed. Eighteen hours after the cardiac arrest, a quadruple coronary artery bypass grafting operation was undertaken. During surgery, a fresh thrombus was removed from the middle left anterior descendent artery. Post-operative course was uneventful and the patient was discharged seven days after the procedure. Twenty four months later, he remains asymptomatic. In this case, the immediate call for the Advanced Life Support team, prompt basic life support and the successful defibrillation, altogether, contributed for the full recovery. Furthermore, the swiftness in the detection and treatment of the acute reversible cause (myocardial ischemia in this case) was crucial for long-term prognosis.</p
