Study Notes
Risk Factors for Cardiovascular Conditions
- Modifiable risk factors include psychological states such as Type A personality, stress, depression, anxiety, hostility, and anger.
- Increased catecholamines due to stress can lead to endothelial injury, elevated heart rate, and heightened myocardial contraction, increasing oxygen demand.
- Elevated homocysteine levels, caused by the breakdown of methionine, damage endothelium and promote plaque buildup.
- Substance use, particularly cocaine and methamphetamine, can induce coronary artery spasm, resulting in chest pain and myocardial infarction (MI).
Interprofessional and Nursing Care
- Identify high-risk individuals through health history, presence of cardiovascular symptoms, lifestyle patterns, psychosocial history, employment history, and beliefs about health.
- Management strategies should focus on preventing and controlling modifiable risk factors, encouraging lifestyle changes, and setting realistic health goals.
Impaired Perfusion
- Poor central perfusion results from vessel blockages leading to impaired blood flow and excessive edema impeding oxygen exchange.
- Consequences of impaired perfusion include ischemia, irreversible cell injury, and necrosis.
- Non-modifiable risk factors for impaired perfusion include age, sex, genetics, and ethnicity.
- Modifiable risk factors are smoking, obesity, hyperlipidemia, hypertension (HTN), diabetes, and a sedentary lifestyle.
Hypertension
- A significant modifiable risk factor for cardiovascular disease (CVD), affecting approximately 46% of adults in the U.S.
- Contributes to MI, heart failure, stroke, renal disease, and retinopathy.
- Highest prevalence in African Americans, with earlier onset and greater organ damage compared to other ethnic groups.
Gender and Ethnicity
- Men are more prone to hypertension before middle age, whereas women's rates increase 2-3 times with oral contraceptives and after menopause.
- Hispanic individuals often have lower rates of treatment, awareness, and control of hypertension.
Normal Blood Pressure Regulation
- Blood pressure is influenced by cardiac output (CO) and systemic vascular resistance (SVR), crucial for maintaining tissue perfusion.
Etiology of Hypertension
- Primary hypertension accounts for 90-95% of cases, with contributing factors including endothelial dysfunction, increased sodium intake, obesity, and tobacco use.
Lifestyle Modifications for Hypertension Management
- Recommendations include weight reduction, a DASH diet, low sodium intake, moderation of alcohol consumption, regular physical activity, and avoiding tobacco.
Causes of Secondary Hypertension
- Neurological disorders, increased intracranial pressure, sleep apnea, vascular issues like coarctation of the aorta, pregnancy, medications, and renal disease can all contribute to secondary hypertension.
Hypertension Drug Therapy
- Goals for BP management vary by age and health status, generally aiming for SBP < 130 mmHg for those over 65, and 130/80 mmHg for younger adults with existing CVD or risk factors.
Risk Factors for Coronary Artery Disease (CAD)
- Diabetes increases the risk of CAD by 2-4 times and contributes to endothelial dysfunction and altered lipid metabolism.
- Metabolic syndrome encompasses multiple risks related to insulin resistance, including central obesity, hypertension, abnormal lipids, and elevated fasting blood glucose.
Clinical Manifestations of Peripheral Artery Disease (PAD)
- Intermittent claudication indicates ischemic muscle pain from consistent exercise, resolving within 10 minutes of rest.
- Paresthesia involves numbness or tingling in extremities due to nerve ischemia, often leading to unnoticed injuries.
Signs of Reduced Blood Flow to Limbs
- Manifestations may include shiny skin, hair loss, diminished pulses, pallor with leg elevation, and reactive hyperemia when the limb is lowered.
Pain and Complications Associated with PAD
- Rest pain suggests worsening disease, commonly in feet or toes, aggravated by limb elevation and alleviated by gravity.
- Complications of prolonged ischemia lead to skin and muscle atrophy, delayed healing, infections, tissue necrosis, and arterial ulcers.
