Study Notes

Assessment and Diagnostics

Hypertension (HTN), characterized by consistently elevated blood pressure, Peripheral Vascular Disease (PVD), which involves narrowing of blood vessels affecting blood flow, and Preeclampsia, a pregnancy-related hypertensive disorder, are critical conditions impacting organ perfusion and overall cardiovascular health.
Family history and lifestyle habits are critical factors for assessing HTN.
Previous diagnoses or treatments for HTN must be reviewed to inform current assessments.
Key physical assessment findings include headaches, blurred vision, chest pain, and murmurs indicating rhythm changes.
Peripheral assessments include capillary refill comparisons and checking for pulse presence and symmetry in lower extremities.
Skin changes such as color, temperature, and hair loss indicate PVD.
Edema may present as rapid swelling in face, hands, and feet in preeclampsia, requiring careful monitoring.

Diagnostics

Ankle Brachial Index (ABI) is crucial for diagnosing PVD; a ratio of blood pressure in the ankle versus the arm signals potential vascular issues.
Blood pressure readings of ≥140/90 suggest hypertension and necessitate further investigation.
Thrombocytopenia (low platelet count) is associated with severe cases of preeclampsia and demands CBC assessment.

Concept: Perfusion

Defined as blood flow through arteries and capillaries, delivering oxygen and nutrients to cells.
Altered perfusion may lead to impaired tissue circulation, highlighting the need for timely assessment and intervention.

Non-modifiable factors include:
- Age: Increased risk with advancing years.
- Genetics: Family history of conditions like Marfan syndrome can elevate risk.
- Gender: Males face a higher risk.
- Ethnicity: African Americans are noted to have higher incidences of vascular issues.
Modifiable factors include:
- Hypertension: Manageable through lifestyle changes and medication.
- Smoking: Contributes to vasoconstriction and increased risk.
- Diabetes and High Cholesterol: Modifiable through diet and exercise.
- Obesity and Sedentary Lifestyle: Weight management is crucial for preventing vascular problems.
- Chronic Stress and Alcohol Use: Addressing these can significantly improve perfusion health.

Prevention Strategies for Impaired Perfusion

Primary prevention focuses on health education and promoting healthy blood pressure.
Secondary prevention includes early diagnosis through methods like regular blood pressure analysis.
Tertiary prevention aims to prevent complications such as strokes through lifestyle modifications, including diet, exercise, and smoking cessation.

Pharmacology for Management

Medications for hypertension include:
- Alpha Adrenergic Blockers (e.g., Atenolol, Metoprolol).
- ACE Inhibitors (e.g., Lisinopril).
- Angiotensin II Receptor Blockers (e.g., Losartan, Valsartan).
- Calcium Channel Blockers (e.g., Diltiazem).
- Diuretics (Loop, Potassium-sparing, Thiazide).
- Vasodilators and Magnesium Sulfate are also relevant for managing severe cases.

Cardiac Output and Hemodynamics

Cardiac output is defined as Heart Rate x Stroke Volume.
Pre-load refers to the volume within the ventricles during relaxation; after-load reflects the resistance the heart must overcome to eject blood.
Starlings Law indicates that increased ventricular stretch leads to an increase in stroke volume, emphasizing the importance of careful volume management in perfusion alteration scenarios.
