Introduction to

John N. Hamaty, D.O.
Understand
basic physiology and
hemodynamics of myocardial
depolarization and repolarization
Understand the components of S1, S2,
S3 and S4
Have a maximal understanding of left
ventricular and diastolic pressures and
their association to left atrial filling
Understand basics of stethoscope
hemodynamics
An 82 year old females comes to your office for evaluation. She states
she”thinks” she is taking her medications, but isn’t sure which ones they
are, or how often she take them. Your blood pressure reading is
200/110mmHg. Which point on this hemodynamic tracing would be
effected?
A
B
C
D
C
When someone gets systemic hypertension, the left
ventricular pressure must match systolic pressure; and
therefore the curve would markedly elevated.
The answer would not be B as that is the mitral and
tricuspid valve closure which isn’t effected, and the
answer would not be D as this point on the curve would
not change.
The sound may be accentuated by examination, but the
point on the curve would not change.
Auscultation
Jay Rubenstone,D.O.
Know
what the third and fourth heart
sounds represent
Know grading of murmur by auscultation
Know what the common systolic and
diastolic murmurs represent
Valvular Heart Disease
Jay Rubenstone,D.O.
Know
common etiologies associated
with valvular stenosis and regurgitation
Know how to differentiate degree of
stenosis by valve area
Know the common clinical signs and
symptoms as well as common
echocardiographic findings
associated with decompensation of
aortic stenosis, mitral regurgitation and
aortic regurgitation
A 70 year old female is evaluated here for what is determined to be
rheumatic mitral stenosis. Her calculated valve area is 1. 5cm, her
rhythm is still sinus rhythm. In light of her not yet being a surgical
candidate, appropriate therapy took a turn that she made need surgical
intervention would be the following:
A. Palliative valvuloplasty
B. Afterload reduction with peripheral vasodilators
C. Chronic anti-biotic therapy for chronic rheumatic fever
D. Decrease sodium intake, diuretic therapy, and heart rate control
D
Tell me why…
Pericarditis, Echocardiography
Jerome M. Horwitz, D.O.
Myocarditis
presents most likely in the following
groups:
Young Males
Pregnant Females
Children (especially neonates)
Immunocompromised (HIV)
Pericarditis, Echocardiography
Jerome Horwitz,D.O.
Pericarditis
in the long term
hospitalized patient can be
remembered with the TUMOR
T ~ Tumor / trauma
U ~ Uremia
M ~ Medicines / myocardial infarction
O ~ Other infections (TB, bacterial,
fungal)
R ~ Rheumatoid / radiation
Pericarditis, Echocardiography
Jerome M. Horwitz, D.O.
Echodoppler
study is safe, reproducible, cost
effective and available at almost any hospital
A patient is suspected of having myocarditis and a myocardial biopsy is
obtained. It revealed no lymphatic infiltrates and no myocytolysis. The
patient has:
A. Active myocarditis
B. Pericarditis
C. The biopsy was negative therefore your initial diagnosis is wrong
D. Non cardiac chest pain and you order a high resolution CT scan.
B
The answer is B… Pericarditis.
The fact that the biopsy is negative may
exclude myocarditis, but would have no effect
on your CLINICAL diagnosis of pericarditis
Dyslipidemia and the
Use of Statins
Mario Maiese,D.O.
Patients with Framingham risk score >10
(considered moderate risk with metabolic
syndrome and all patients with known
vascular disease (CAD,PAD,Carotid,AAA
or TIA) or vascular disease equivalents
(DM or CKD) are candidates for statin
therapy to prevent primary or recurrent
CV events per the present guidelines
Dyslipidemia and the
Use of Statins
Mario Maiese,D.O.
Patients with diabetes and/or metabolic syndrome
(pre-diabetes) will frequently have triglyceride
(TG)/HDL-C axis disorders (high TG and low HDL-C.) In
these patients especially and probably all patients,
non HDL-C is a better than LDL-C as a surrogate
marker of CV risk and is also a better treatment goal.
(It is the secondary treatment goal after LDL-C in
patients with TG >200 mg/dL per NCEP ATP III.)Non
HDL-C, if not already calculated on your lab results, is
the total cholesterol (TC) minus the HDL-C. The non
HDL-C goal of treatment is 30 mg/dL. The “optional”
lower treatment goals for non-HDL-C should be used
because of the ever present residual risk and proven
benefits of high-dose statins
Dyslipidemia and the
Use of Statins
Mario Maiese,D.O.
Statins are the drug of choice for CV risk reduction.
Safety and cost should always be considered in
choosing a statin. Considering what we know about
the lipophilic and metabolic properties of certain
statins (lovastatin and simvastatin) associating them
with increased risk and drug interactions, pravastatin
can easily and safely be substituted for either without
compromising efficacy. Pravastatin 80mg is
equivalent in potency to 40mg simvastatin (~40%
reduction in LDL-C.) If a more potent statin is needed
for lipid lowering (simvastatin 80mg is not an option
for new patients) then generic atorvastatin 40mg80mg , cheaper; or rosuvastatin 20mg-40mg, generic
not yet available) would be recommended.
Which of the following are true regarding non HDL-C?
A. It is a better surrogate than LDL-C in abnormalities of the
TG/HDL axis?
B. It is usually a better surrogate than LDL-C in patients with
type 2 DM and metabolic syndrome
C. Non HDL-C is the TC minus HDL-C
D. In type 2 DM without known CVD the non HDL-C goal would
be <130mgdL
E. We should start looking at non-HDL-C probably when TG is
>130 mg/dL, even though the guidelines direct us to make
that our secondary goal when TG is >200 mg/dL

A 62 year old executive comes to your office for evaluation prior to
beginning an exercise program. He is a distant smoker and has a history
of controlled hypertension. He is not having specific angina symptoms but
clearly has been extremely sedentary and wants to change his lifestyle.
Your physical examination is generally unremarkable; the ECG reveals a
normal sinus rhythm with a left bundle branch block.
Which of the following stress testing is most appropriate:
A. Pharmacologic stress testing
B. Routine treadmill stress test
C. Dobutamine stress echocardiography
D. Treadmill stress echocardiography
A
The answer can only be pharmacologic testing for one simple
reason….
The patient has an underlying LBBB, which immediately obscures
the ecg, therefore treadmill of any kind, or any change in heartrate
such as dobutamine could not occur.

Syncope / Pacemakers & ICD’s

pacing

Management of the patient presenting with
syncope
Syncope / Pacemakers & ICD’s
Yega Raman,D.O.
In
the absence of structural heart disease,
neurocardiogenic syncope is the most
common cause of syncope. Diagnosis by
history and tilt table is often useful.
Unexplained syncope in the presence of
significant structural heart disease carries
a poor prognosis; may need invasive
electrophysiologic testing to look for
brady and tacky arrhythmias
Syncope / Pacemakers & ICD’s
Yega Raman,D.O.
Pacemaker mode selection is influenced by the
underlying atrial rhythm. In patients with permanent
atrial fibrillation with symptomatic slow ventricular
response and normal LV function, a single chamber
ventricular pacemaker is indicated
ICD is indicated for secondary and primary prevention
of sudden cardiac death in appropriate patients
