Q

Diagnosis of Acute Coronary Syndrome (ACS)

  • A complete blockage of a coronary artery means you suffered a (1)
  • A partial blockage translates to a (1)
  • Labs tests: (3)
  • E___
  • E________
A
  • A complete blockage of a coronary artery means you suffered a STEMI heart attack – which stands for ST-elevation myocardial infarction.
  • A partial blockage translates to an NSTEMI heart attack – a non-ST-elevation myocardial infarction.
  • Labs tests: Troponin, CPK, CK-MB
  • EKG
  • Echocardiogram
  • ** Troponin is needed every 46 hours inpatient.*
  • Echo should be read by cardiology ideally not radiology*
  • If high suspicion – troponin shouldn’t really be taken in primary care office – should send to ED*
  • NSTEMI = partial blockage, STEMI = complete blockage*

Q

What does this EKG show?

A

This EKG was from a patient who went on to develop ST elevation and V-fib arrest. If you are suspicious of hyperacute T waves, get frequent repeat EKG’s to identify ST elevation or other evolution

Beware the Hyperacute T wave in the setting of chest pain. Hyperacute T waves may not always have ST elevation. The real key is the T wave’s size in relation to the QRS complex. This EKG was from a patient who went on to develop ST elevation and V-fib arrest. If you are suspicious of hyperacute T waves, get frequent repeat EKG’s to identify ST elevation or other evolution.

Q

What does this EKG Show?

A

Cerebral T waves which can be seen in subarachnoid hemorrhage. Subarachnoid hemorrhage can cause changes on the EKG such as deep t wave inversions or ST elevation. -> not everything on an EKG is from a cardiac cause

ECG Findings of Cerebral T Waves

  • Inverted, wide T waves are most notable in precordial leads (can be seen in any lead).
  • QT interval prolongation.

Pearls

  • These are associated with acute cerebral disease, most notably an ischemic cerebrovascular event or subarachnoid hemorrhage.
  • They may be accompanied by ST segment changes, U waves, and/or any rhythm abnormality.
  • Differential diagnosis includes extensive myocardial ischemia.
  • Strongly suspect an intracranial etiology in a patient with altered mental status and these electrocardiographic findings. (Atlas of EM)

NYP STEMI Protocol

A

NYP STEMI Protocol

  • Do NOT give beta blocker if hypotensive
  • TNK (we never really give tenecteplase unless neuro thinks they’re having an acute event)
  • Stat meds can be given all at once

Long term maintenance

  • Plavix common but slowly moving towards ticagrelor-Should not be on nitrate, P2y12, and warfarin at once, will wean off nitrate and be on the other two-LIFETIME beta blocker!

Management of Acute coronary syndrome Main Procedures 1. **(3)** * Special tubing with an attached deflated balloon is threaded up to the coronary arteries. The balloon is inflated to widen blocked areas where blood flow to the heart muscle has been reduced or cut off. * _Often combined with implantation_ of a stent to help open blocked arteries. 2. **(1)** Similar to angioplasty except that the catheter has a laser tip that opens the blocked artery. Pulsating beams of light vaporize the plaque buildup. 3. **(1)** needed when 3 or more diseased arteries/blockages
1. **Angioplasty [Percutaneous Coronary Interventions [PCI], Balloon Angioplasty and Coronary Artery Balloon Dilation.** * Special tubing with an attached deflated balloon is threaded up to the coronary arteries. The balloon is inflated to widen blocked areas where blood flow to the heart muscle has been reduced or cut off. * _Often combined with implantation_ of a stent to help open blocked arteries. 2. **Angioplasty, Laser:** Similar to angioplasty except that the catheter has a laser tip that opens the blocked artery. Pulsating beams of light vaporize the plaque buildup. 3. **CABG- Coronary artery bypass surgery** needed when 3 or more diseased arteries/blockages

Heart Disease Risk Evaluation in Women - Summary Algorithm
Main point is Do risk assessment for women! Often overlooked
38
Case Study 1 ## Footnote Patient A was a woman, 88 years of age, who lived in an assisted living retirement home. She had been a widow for 20 years, after losing her husband to long-term complications associated with diabetes. Until approximately seven years ago, Patient A had been in relatively good health with no major health problems, but she suffered a mild stroke at 81 years of age. At that time, she decided to quit her 50- to 60-year smoking habit. Other than her smoking history, she did not have any other significant cardiovascular risk factors. After recuperating from her stroke, Patient A decided to leave her apartment and move into the assisted living facility where she would not only have some companionship but also receive assistance with meals and transportation to doctor's appointments and other activities. About six years after suffering the cerebrovascular accident, she had a bout of heart failure. She was admitted to the local hospital and received oxygen per nasal cannula, IV furosemide, and digoxin. After two weeks in the hospital, the patient was discharged home in apparently better condition. However, two days after returning home Patient A suffered a sudden cardiac death event at the breakfast table. Efforts at resuscitation were unsuccessful. 1. What coronary risk factors are present? What risk factors are negative? 2. Is the patient's chest pain syndrome typical or atypical for women? Why or why not?
Smoking, stroke, age. Negative risk factors no DM, HTN. not typical for a women, sudden cardiac death more common for men - her MI was probably missed/ had it before the heart failure
39
Case Study 2 ## Footnote **Patient S** is caucasian woman, 43 years of age, and mother of three small children. She has a long-standing history of significant obesity with little success in dieting over the years. At 5'3", she is obese, weighing 220 pounds. Her fat distribution is "apple-shaped" and consequently, her waist-hip ratio is more than the 0.8 normal range. In addition, Patient S lives a fairly sedentary lifestyle and does not have a regular exercise program. Her dietary habits do not take into account basic recommendations for cardiac nutrition. **Patient J** is 55 years of age and teaches high school English. Her coronary risk factor profile includes a 30-pack-year history of cigarette smoking and altered lipid levels. Her HDL is only 35 mg/dL and her LDL is 145 mg/dL. Patient J has tried with little success to control her cholesterol with diet. Recently, she began taking gemfibrozil as prescribed by her family physician, but has not followed his recommendation to quit smoking and enroll in a smoking cessation program at a local hospital. Rather, she continues to smoke one pack of cigarettes per day. **Patient V** is a woman, 47 years of age, who has a family history of heart disease. Although she denies ever experiencing cardiac symptoms, her brother suffered a nonfatal MI at 46 years of age and her father had an MI at 53 years of age. Both of these cardiac events were medically managed. However, her father's disease did progress to the point that he underwent CABG surgery five years ago. He had three coronary artery lesions bypassed. In addition to her family history, Patient V is approximately 30 pounds overweight and does not exercise on a regular basis. She drinks approximately two to three glasses of red wine per day and has never smoked. **Patient D** is 67 years of age and lives in an assisted living retirement community. An insulin-dependent diabetic since adolescence, Patient D is unable to care for herself due to the effects of the diabetes on her eyesight, as well as the development of peripheral neuropathies. In addition to the diabetes, Patient D continues to smoke. By now, she has a 40-pack-year history of smoking. **Patient F** is an African American woman, 36 years of age, with a history of mild hypertension. Her blood pressure has been fairly well controlled on an ACE inhibitor over the past two years. Patient F eats a well-balanced, nutritious diet, exercises three to five times a week, and does not have a history of smoking or alcohol use. However, she does exhibit many of the characteristics of the Type A behavior pattern, such as excessive competitiveness, being harried, and rushing to complete more and more tasks in an ever-shrinking period of time. In addition to these characteristics, she exhibits a somewhat cynical or negative outlook with occasional expression of hostile or angry thoughts and feelings. **1.****Which of these women is at greatest risk for heart disease?** **2.****Who is at least risk?** **3.****What recommendations would you make in counseling each patient regarding her cardiovascular health?**

Carotid Artery Stenosis * These arteries carry blood to the h\_\_\_\_, f\_\_\_\_, and b\_\_\_\_. * Carotid artery stenosis can be caused by **(1)** build-up in the blood vessels (ath\_\_\_\_\_\_). * Thromboses in coronary and cerebral arteries are complications of ath\_\_\_\_\_\_\_. * Condition is present for a long time before _______ appear. * St\_\_\_\_\_ or T\_\_\_s may occur. * Carotid artery stenosis, accounts for approximately 18%–25% of (1)
* These arteries carry blood to the head, face, and brain. * Carotid artery stenosis can be caused by cholesterol build-up in the blood vessels (atherosclerosis). * Thromboses in coronary and cerebral arteries are complications of atherosclerosis. * Condition is present for a long time before symptoms appear. * Stroke or TIAs may occur. * Carotid artery stenosis, accounts for approximately 18%–25% of ischemic stroke *Same risk factors as CAD - so treat the modifiable risk factors*
41
CAS Detection 1. **(1)** uses sound waves to create real-teim pictures of the arteries and locate blockages. Doppler is a special ultrasound technique that can detect areas of restriced blood flow in the artery. 2. **_(_1)** uses a CT scanner to produce detailed views of the arteries in the neck. The test is particularly useful for patients with pacemakers or stents. 3. **(1)** noninvasive test gives information similar to CTA without using ionizing radiation. 4. **(1)** minimally invasive test in which a catheter is guided through an artery in the groin to the area of interest in the brain. Contrast material is injected through the tube and images are captured with x-rays.

Case Study 3 ## Footnote A 67-year-old man comes to your office for a regularly scheduled visit. He has type 2 diabetes mellitus and a 40-pack-year smoking history, but he quit smoking two years ago. He takes lisinopril and atorvastatin (Lipitor); his blood pressure today is normal. His A1C and lipid panel at his last visit were within normal limits. He says that he feels well and has no neurologic complaints or any other symptoms. His father had a stroke at 68 years of age and was told it was caused by a blocked artery in his neck. The patient asks whether he should be screened for the same kind of blockage.

Hypertensive Urgency For the general treatment of hypertensive crisis, patients should be classified as having hypertensive emergency or hypertensive urgency **Treatment =** **Requires ICU or hospital admission?** **Why do we not want to over aggressively correct the BP?**
Initiating, reinitiating, modifying, or titrating oral therapy to gradually reduce BP over 24-48hrs Usually does not require ICU or hospital admission May potentially cause harm due to too rapid a decrease in blood pressure bc their end organs have adapted to chronically elevated blood pressures, setting a new physiologic “norm” of autoregulation. This new “norm” leads to optimal organ perfusion at a higher baseline blood pressure
52
Hypertensive Emergency Treatment Goal = Why do we not want more aggressive therapy? What should you do if you do see signs of neuro deterioration? After the first hour?
**Reduce mean arterial pressure (MAP) by 25% over the first hour of therapy.** **\> 25% reduction associated with cerebral ischemia**. DC therapy if signs of neuro deterioration After the first hour; a more gradual blood pressure reduction is recommended

Hypertensive Emergency Algorithm
61
Patient Care Scenario **Classify this patient’s hypertensive crisis and decide on the appropriate treatment goals.** * A 52-year-old man with a medical history of hypertension, sarcoidosis, and asthma presents to the ED with new severe, sharp headache. * He states that it started about 3 hours ago and is getting worse. * The patient’s vital signs include blood pressure 192/102 mm Hg, heart rate 78 beats/minute, respiratory rate 20 breaths/minute, and pain 9/10, while afebrile. * Laboratory test results show SCr 0.8 mg/dL (baseline 0.7 mg/dL), AST 32 U/L, total bilirubin 0.7 mg/dL, and lipase 40 units/L. * A head CT reveals a small acute ICH with no mass effect or edema.
First, determine whether the patient has signs or symptoms of target-organ damage. In general, the patient’s physical examination and presenting symptoms will lead toward which diagnostic tests and laboratory assays to use. Laboratory values do not always indicate specific target-organ damage. Diagnostic head CT evaluation reveals target organ damage to the brain, specifically the development of an ICH. Because of this finding, the patient qualifies for a hypertensive emergency warranting intravenous therapy and ICU admission. * With his acute ICH, this patient would qualify as an exception to the general treatment principles for hypertensive emergency. In addition, with ICH, further delineation is required. Although rapid, aggressive blood pressure lowering has been shown to be safe, these large studies excluded patients with large ICH volumes, ICP elevations, and/or severe elevations in blood pressure (SBP greater than 220 mm Hg). * Because G.A. does not meet any of these exclusion criteria, the blood pressure goal would be SBP less than 160 mm Hg within the first few hours, being mindful of overaggressive correction. *Ans: hypertensive emergency, tx goal of reducing BP by no more than 25% in first hour, ICU admission*

Case 4 ## Footnote A 54-year-old woman presented to the telemetry floor with shortness of breath (SOB) for 4 months that progressed to an extent that she was unable to perform daily activities. She also used 3 pillows to sleep and often woke up from sleep due to difficulty catching her breath. Her medical history included hypertension, dyslipidemia, diabetes mellitus, and history of triple bypass surgery 4 years ago. Her current home medications included aspirin, atorvastatin, amlodipine, and metformin. No significant social or family history was noted. Her vital signs were stable. Physical examination showed bilateral diffuse crackles in lungs, elevated jugular venous pressure, and 2+ pitting lower extremity edema. ECG showed normal sinus rhythm with left ventricular hypertrophy. Chest x-ray showed vascular congestion. Laboratory results showed a pro-B-type natriuretic peptide (pro-BNP) level of 874 pg/mL and troponin level of 0.22 ng/mL. Thyroid panel was normal. An echocardiogram demonstrated systolic dysfunction, mild mitral regurgitation, a dilated left atrium, and an ejection fraction (EF) of 33%. How would you manage this case?
