E. Hydralazine is a direct-acting arteriolar vasodilator. There is a definite survival advantage with the use of hydralazine in combination with nitrates in systolic dysfunction. Candesartan is associated with hyperkalemia as well. Dialysis is sometimes used in hyperkalemia, but only if associated with renal failure as the cause.
99
What is the answer if the patient is still dyspneic after using ACE inhibitors, beta blockers, diuretics, digoxin, and mineralocorticoid inhibitors?
Ivabradine: SA nodal inhibitor of "funny channels" that slows the heart rate. Add it to systolic dysfunction if the pulse is over 70 bpm or beta blockers can't be used. Ivabradine decreases symptoms.
Sacubitril/Valsatran: Used instead of an ACE inhibitor. Sacubitril is added only to an ARB. This neprilysin inhibitor does provide a mortality benefit for systolic dysfunction.
Hydralazine/Nitrates: Used when neither an ACE inhibitor nor an ARB can be used as vasodilator therapy. May add efficacy to ACE inhibitor or ARB in some patients.

159
What is the only truly accurate test for myocarditis?
Biopsy of the heart
160
What will echocardiography show in a patient with Myocarditis?
Decrease in ejection fraction
161
What is the most common infection in Pericarditis?
Viral
162
_________ is associated with sharp chest pain that changes in intensity with respiration as well as the position of the body. The pain is worsened by lying flat and improved by sitting up.
Pericarditis
163
What medication decreases the recurrences of pericarditis?
Colchicine
164
A 78-year old man with a history of lung cancer comes to the ER with several days of increasing shortness of breath. He became somewhat lightheaded today, and that is what has brought him to the hospital. On physical examination, he has a blood pressure of 106/70; pulse of 112; jugulovenous distention; and the lungs are clear to auscultation. The blood pressure drops to 92/59 on inhalation. Which of the following is the most appropriate to confirm the diagnosis?
a. EKG
b. Chest X-Ray
c. Echocardiogram
d. Right heart catheterization
e. Cardiac MRI
C: Echocardiogram
165
Patient has edema, ascites, enlargement of the liver and spleen, JVD, and calcification on Chest X-Ray. What is the most likely diagnosis?
Constrictive Pericarditis
166
Patient has hypotension, tachycardia, distended neck veins, clear lungs. What is the most likely diagnosis?
Pericardial Tamponade
167
What is the best initial test in Constrictive Pericarditis?
Chest X-Ray
It'll show calcification and fibrosis
168
In Constrictive Pericarditis, what will you give first to decompress the filling of the heart and relieve edema and organomegaly
Diuretics
169
Patient has leg pain in the calves upon exertion and is relieved by rest. It occurs when walking up or down hills. The skin appears to be smooth and shiny. What is the most likely diagnosis?
Peripheral Artery Disease
170
What is the best initial test in PAD?
Ankle-brachial index
If ABI less than 0.9 or difference between ankle and brachial BP is greater than 10%, then disease is present
171
What is the most accurate test in PAD?
Angiogram
172
What is the best initial therapy for PAD?
Aspirin or vorapaxar
Stop smoking
Cilostazol (single most effective medication)
173
A 67-year-old man comes to the ER with the sudden onset of chest pain. He also has pain between his scapulae. He has a history of hypertension and tobacco smoking. His blood pressure is 169/108. What is the best initial test?
a. Chest X-Ray
b. Chest CT
c. MRA
d. Transesophageal echocardiogram
e. Transthoracic echochardiogram
f. CT angiogram
g. Angiography
A. Chest X-Ray
might show widening of the mediastinum, which is an excellent clue as to the presence of aortic dissection
174
Patient has pain in between scapulae and difference in blood pressure between the arms, what is the most likely diagnosis?
Aortic Dissection
175
A 67-year-old man comes to the ER with the sudden onset of chest pain. He also has pain between his scapulae. He has a history of hypertension and tobacco smoking. His blood pressure is 169/108. What is the most accurate test?
a. MRA
b. Transesophageal echocardiogram
c. Transthoracic echocardiogram
d. CT angiogram
e. Angiogram
E. Angiography is more accurate than any other choices
MRA = CTA = TEE (No difference in accuracy)
176
Treatment for Aortic Dissection
1. Beta blockers
2. Nitroprusside
3. Surgical correction
*BB must be started before nitropusside to protect against reflex tachycardia of nitroprusside which will worsen shearing forces
177
Which of the following is the most appropriate screening for aortic aneurysm?
a. Everyone above 50 with CT angiography
b. Men who ever smoked above 65 with ultrasound
c. Everyone above 50 with ultrasound
d. Everyone above 65 with ultrasound
e. Men above 65 with ultrasound
B.
AAA > 5 cm --> surgical or catheter-directed repair
New-onset back pain in elderly patients (>65) should have ultrasound of aorta to rule out AAA
178
Which of the following is the most dangerous to a pregnant woman?
a. Mitral stenosis
b. Peripartum cardiomyopathy
c. Eisenmenger phenomenon
d. Mitral valve prolapse
e. Atrial septal defect
B
Peripartum cardiomyopathy develops after delivery in most cases; that is why ACEIs/ARBs are acceptable to use
179
Give 5 medical treatment for Peripartum Cardiomyopathy
1. ACEIs/ARBs
2. Beta blockers
3. Spironolactone
4. Diuretics
5. Digoxin
180
This is the development of a right-to-left shunt from pulmonary hypertension
Eisenmenger Syndrome
