Pathophysiology of Coronary Diseases
Pathophysiology of Coronary DiseasesDescribe the pathophysiology of coronary artery disease (what is it / signs symptoms / tr decimatements / outcomes desired.Coronary Artery disease (CAD) occurs when fatty plaques argon built up in arteries and harden with age. This is known as Artherosclerosis which results in a decreased amount of smear being delivered to the optic and increased difficulty for the arteries to dilate (Lewis, 2014). The sum then shifts from an aerobic metabolism to anaerobic metabolism due to the resulting atomic number 8 deprivation from the vessels not being able to keep up with the increased demand for oxygen (Lewis, 2014). Lactic sulphurous then accumulates and leads to acidosis, decreased energy, decreased takeion strength and also decreased squelch (Lewis, 2014). This chain of events means that less relationship leaves the heart which slew then lead to myocardial infarction (MI) (Lewis, 2014).G rarityerSigns and SymptomsMaleCrushingSqueezing nearnes s in neck, thorax, or shoulder bladeCAD is broad(prenominal)est among white, middle aged menFemaleJaw, neck, back, and shoulder painShortness of breathVague chest painDizzinessPalpationsCold sweats nauseaMay be to a greater extent difficult to identifyTreatment OptionsSome examples of medicationsNitratesReduce the amount of oxygen that the heart uses.Lipid Lowering DrugsInhibit the synthesis of cholesterol in the liver which unexplainably increases hepatic LDL receptors. The liver is then able to remove more LDLs from the blood.Simvastatin (Zocor)Niacin (Niaspan)Gemfibrozil (Lopid)Beta Adrenergic BlockersReduce oxygen demands and workload by reducing heart rate and blood flow peripheral device resistance (Lewis, 2014).Angiotensin-Converting Enzyme InhibitorsResult in vasodilation and reduced blood volume. These drugs also reverse or prevent ventricular remodeling (Lewis, 2014).Anti-Platelet DrugsReduce platelet accumulation and decrease the attempt for a blockage to develop in b lood vessels.SurgicalLaser angioplastyCoronary artery bypassShunt placement anticipate OutcomesIncrease in cardiac widening decline of blood stormImproving quality of lifeReduction of chest painDescribe the pathophysiology of hypertension. (What is it / signs symptoms / interventions / outcomes desired / lifestyle changes needed.hypertensionPrimary Hypertension reverend blood pressure (BP) without an identified etiology (Lewis, 2014).Contributing Factors (Lewis, 2014)Increase sympathetic nervous system activityOverproduction of sodium retaining hormones and substances that cause vasoconstrictionIncreased sodium intakeObesityDiabetesTobacco useExcessive alcohol consumptionPathophysiology of Primary HypertensionIncreased cardiac output (CO) or Systemic vascular resistance (SVR) increases. This happens due to abnormalities of any of the mechanisms involved in the maintenance of normal BP (Lewis, 2014). The release of renin or angiotensin II causes the blood vessels to increase whic h consequentially increases blood volume.Signs and Symptoms of Primary HypertensionBP 140/90 on two separate occasionsNauseaHeadache, typically throbbing and occurring in the morning. stack problemsTreatmentIncludes lifestyle modifications includingStress reductionDietExerciseLimit alcohol intakeTobacco cessationRelaxation techniquesSecondary HypertensionElevated BP with a precise cause that can be correctedPathophysiology of Secondary HypertensionIncrease in blood volume is due to a specific disease or illness.Signs and symptoms of Secondary HypertensionStrokeHeart FailureMIRetinopathyLeft Ventricular HypertrophyTreatmentTreating the underlying cause some(prenominal) types of Hypertension can be treated with medications such asThiazide diuretics wholeness inhibitorsBeta adrenergic blockersAlthough these are some signs listed in our text there are really no definite signs or symptoms because a patient cannot tell if their blood pressure is consistently high school just by the way they feel. The modify listed above happen because there are no signs a person can feel on their own to warn them of their hypertension (Lewis, 2014).Describe the pathophysiology of left sided heart failure / CHF (what is it / signs symptoms / treatments / outcomes desired / lifestyle changes needed.Left sided heart failure is due to the left ventricle ineffectively contracting. This causes a decrease in CO and pulmonary edema. These occur because the heart is not pumping effectively causing fluid to build up in the left atrium as well as the lungs (Lewis, 2014).Signs and SymptomsCrackles perceive in the lungsFrothy pink sputum Attention spanVentricular gallopDifficulty breathingMuscle weaknessEdemaFatigue cargo gainIrritabilityTreatment OptionsLifestyle Modifications Sodium intake risk for fluid overloadAce Inhibitors vascular resistanceDiuretics PreloadAdvise patient to eat viandss high in kB or consume a potassium supplement to replace fluids lostDigoxin Hearts ability to co ntractBeta-BlockersPrevent cardiac remodeling(Lewis, 2014)Create an Education plan for a low sodium diet. (What specifically would you teach this patient about this diet)? Include foods high in sodium / foods to avoid.enthral have a detailed plan that you can use to teach a patient. The plan should have at least 2 patient outcomes listed. You need to bring the plan to clinical so that you can use it with your patient. Educate patient that sodium intake is as follow red-blooded AdultNo more than 2300 mg/ twenty-four hoursCardiac PatientLess than 1500 mg/ daytimelightAdvise patients not to add salts or seasonings to foods because it can increase sodium intake. They can choose options such as non-sodium seasonings instead (For Example Mrs. Dash offers AMAZING no-salt seasonings)Also, advise patient that using herbs for seasoning manage garlic, ginger or lemon are good alternativesFoods to AvoidFrozen mealsLimit milk intake to no more than 2 cups a dayCheesesCanned soups and vegetable sAdvise patient if buying canned vegetables he/she can rinse these front to eating with waterProcessed meatsAlways read your food labelsWatch out for medications that contain sodiumOutcomesPatient 1Patient will be able to name 3 alternatives to seasoning with salt by end of shift, Tuesday 12pm.Patient 2Patient will be able to name 3 food choices low in sodium by end of shift, Tuesday 12pm.(Lewis, 2014)Create an education plan for low fat, heart healthy diet. (What specifically would you teach this patient about this diet?) Include information on problematical fats versus good fats.Please have a detailed plan that you can use to teach a patient. The plan should have at least 2 patient outcomes listed. You need to bring the plan to clinical so that you can use it with your patient. Daily Fat Consumption25-35% of effortless caloriesPolyunsaturated should be the special sourceFood ChoicesAdequate intake of foods with omega 3 fatty acids have proven to be good for the heart (American Heart Association)Eat search at least two times a week (American Heart Association) omega-3 fatty acids decrease risk of arrhythmias, which can lead to sudden death. omega-3 fatty acids also decrease triglyceride levels, slow growth rate of atherosclerotic plaque, and lower blood pressure (American Heart Association).Eat moreWhole grains flip vegetables and fruitIf you cannot afford fresh fruit try fruit canned in natural juices versus syrupsLow fat cheeses and dairyAvoid processed foods, and those high in saturated fatsFoods high in saturated fats includeButterBaconCheeseOutcomesPatient 1Patient will be able to give tongue to ways to decrease fat consumption on a daily basis by end of shift, Tuesday 12pm.Patient 2Patient will be able to verbalize the need for consumption of Omega 3 fatty acids by end of shift, Tuesday 12pm.Give examples of situations when you would need to increase oral intake of foods high in potassium.Patients with hypertension on a potassium wasting diuretic, diarrhea, laxative abuse, vomiting, and ileostomy drainage would need to increase oral intake of foods high in potassium or take a potassium supplement (Lewis, 2014, p. 297).Give examples of situations when you would need to decrease oral intake of foods high in potassium.(Note this could be in look to disease processes or medications)Prepare a list of foods high in potassium. Please bring the list to clinical that you could use to teach the patient.Patients taking ACE Inhibitors, Potassium Sparing Diuretics or NSAIDS may need to decrease their intake of oral potassium (Lewis, 2014, p. 296). Also, patients who have nephritic disease, burn victims, Addisons disease, Tumor Lysis Syndrome and those with adrenal gland insufficiency may also need to decrease their intake of oral potassium (Lewis, 2014, p. 296).Foods High In PotassiumFruitsVegetablesOther FoodsApricot, avocado, banana, cantaloupe, dried fruits, grapefruit juice, honeydew, orangish, orange juice, prunes and raisinsBak ed beans, butternut squash, refried beans, black beans, cooked broccoli, carrots, greens (except kale), canned mushrooms, white and sweet potatoes, cooked spinach, tomatoes or tomato products, and vegetable juicesBran or bran products, chocolate, granola, milk, nuts, seeds, peanut butter, salt substitutes, salt liberal broth and yogurt(Lewis, 2014, p. 1115)Using the following template, prepare the following medication which many of the patients on 7S take (Remember that these are cardiac patients when looking at the indications of the medication) Please do not written matter and paste from medication resource, complete in your own words.
