UMDNJ~ SOM SECOND YEAR CARDIOLOGY MODULE FALL SEMESTER COURSE REVIEW 2012 John N. Hamaty, DO, FACC, FACOI Course Director

Students, included in this review are basic bullet review points for each lecture in your cardiology module. Please be aware your exam questions may include, BUT ARE NOT LIMITED TO the information in this review. Review of all material, PowerPoint presentations, and teaching points discussed during the actual lecture presentation is encouraged advised, and your individual responsibility.

Introduction to Hemodynamics 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

 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 40mg- 80mg, cheaper; or rosuvastatin 20mg-40mg, generic not yet available) would be recommended. Dyslipidemia and the Use of Statins Mario Maiese,D.O.

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 Well? Which statements are true?

All of them!

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 Yega Raman,D.O.  Indications for temporary and permanent pacing  Choice of pacing modes  Indications for ICD/Biventricular devices  Etiology and pathogenesis of syncope  Tests to determine the etiology of syncope  Management of the patient presenting with syncope

 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  Primary prevention of SCD: Cardiomyopathy with LVEF ≤CHF NYHA Class II-III narrows QRS  Bi-ventricular ICD (Cardiac Resynchronization Therapy): Cardiomyopathy with LVEF ≤35%, CHF NYHA Class III- ambulatory Class IV, LBBB with QRS ≥120msec.

Jack Daniels has been a long time alcoholic. He frequent can be found strumming a guitar and drinking a pint of home made bourbon. He usually winds up sleeping on the ground in front of the local tavern. Recently he could not tolerate laying on the ground for more than 15 minutes without having to get up. He is more exhausted and fatigued than ever before, in fact his legs are twice their normal size. When he finally presented to the hospital in congestive heart failure (New York Heart Association Class IV) he needed to be place on a ventilator for a short period of time ( BP: 120/70, heart rate 82bpm).
