Diagnostic testing for heart failure includes chest X-ray, ECG, echocardiography, and pulmonary artery catheterization.In a patient with heart failure, a chest X-ray reveals an enlarged heart, indicating hypertrophy or dilation. If the patient is in the early stages of heart failure, the chest X-ray may show congested pulmonary veins in the upper lobes. If he is in the late stages, the X-ray may show interstitial pulmonary edema and pulmonary effusion. If the patient has biventricular failure, the chest X-ray may show a pleural effusion.

A physician uses an ECG to detect left ventricular hypertrophy. An ECG also detects signs of arrhythmias, such as irregular QRS complexes and F waves, and signs of myocardial ischemia, such as T-wave inversion and ST-segment elevation.

Used to measure the size of the heart chambers, echocardiography may reveal an enlarged right or left atrium. This test also is used to assess ventricular function and to detect ventricular hypertrophy. With normal ventricular function, echocardiography shows concentric contractility, a lack of abnormal wall movement, and a left ventricular ejection fraction of 55% to 60%. With left ventricular hypertrophy, it displays a ventricular wall thickness that exceeds 1.2 cm during diastole.

Pulmonary artery catheters are used to measure cardiac pressures. In right ventricular heart failure, the patient’s right atrial pressure may be elevated. In left ventricular heart failure, his pulmonary artery pressure and pulmonary artery wedge pressure are elevated, and CO is reduced.

To determine if a patient has hypertension, of course, you’ll measure his blood pressure. From his blood pressure measurements, you can determine his pulse pressure and mean arterial pressure (MAP). These measurements, in turn, can help you detect related disorders and understand the effects of certain hemodynamic factors on your patient’s blood pressure.

Arterial System

Arteries, the vessels through which blood travels away from the heart, all carry oxygenated blood, except for the pulmonary arteries, which carry oxygen-depleted blood from the heart to the lungs. The arterial system is made up of vessels of various sizes:

• large, usually elastic arteries, such as the aorta and the pulmonary trunk
• medium-sized arteries, which make up most of the arterial vasculature
• large and small arterioles.

Arteries have nerves bundled along their outer walls. Primarily derived from the sympathetic nervous system, these nerves cause the arteries to contract and relax, thus regulating the flow of blood to various parts of the body.

Arterial Walls

All arteries have three distinct layers. The outer layer (tunica adventitia or externa) is made of strong connective tissue with abundant elastic fibers. The middle layer (tunica media) consists of more elastic fibers than smooth-muscle fibers. The inner layer (tunica intima) is a transparent and highly elastic structure that has direct contact with the circulating blood.

The thickness of each of these layers varies depending on the location of the artery. For instance, large arteries like the aorta or pulmonary arteries typically have a thick tunica media with more elastic fiber than smooth muscle, enabling them to stretch as blood is ejected from the heart during systole and to recoil during diastole. However, arteries located farther away from the heart have less elastic tissue and more smooth muscle. These small-sized to medium-sized vessels are muscular arteries. Together, all arteries help to maintain blood pressure throughout the high-pressure, high-resistance, low-volume arterial system.

Arteries become arterioles when the diameter of the vessel is less than 0.5 mm. The thick smooth-muscle layer of the arterioles enables them to control the flow of blood through the systemic circulatory system by means of vasodilation and vasoconstriction and push the blood through finer arterial structures, the capillaries.

The diagnostic tests for aortic dissection include chest X-ray, ECG, and CT scan. When a patient has a dissecting aortic aneurysm, a chest X-ray may reveal a left pleural effusion. An ECG helps in differentiating aortic insufficiency from ascending aortic dilation and aortic dissection. A CT scan provides information on the location and severity of the dissection.

Some More Facts

Before your patient undergoes surgery, explain the procedure and outline what he can expect in the ICU, including cardiac and PAWP monitoring and I.V. fluid administration. Also, tell him that he may need an arterial line, indwelling urinary catheter, and endotracheal tube.After surgery, explain the need for frequent assessments of vital signs and peripheral pulses to determine the patency of the graft. Also, explain the need for early ambulation to prevent postoperative complications. Instruct the patient on coughing, deep breathing, and splinting the incision and have him perform return demonstrations.

Whether your patient had surgery or was successfully treated with drug therapy, he may be prescribed one or more antihypertensive drugs. Before he goes home, teach him the name of any prescribed drug, the dosage, and its therapeutic and adverse effects. Teach him how to take his blood pressure at home. And demonstrate how to take a pulse.

Discuss the signs and symptoms of a recurring dissection. Stress the pressing need for him to return to a health care facility if the signs and symptoms recur.

If you are suffering from hypertension and are experiencing sudden vision impairment, it’s recommended that you don’t just go out and buy glasses or contact lenses to correct this, but make a thorough examination of the causes of these sight problems. As hypertension can lead to blurry vision for some patients, this can actually be the cause behind your problems, and this is most often not corrected with the usual optical methods, like lenses. The vision impairments your are suffering from are then a result of high blood pressure, which is treated by your regular doctor. It is important however that you make regular visits to your eye doctor, to carefully follow the symptoms.

If your blurry vision isn’t caused by hypertension, you can of course get contacts or glasses, as normal. After a prescription, you are ready to start looking into the market, and this is of course done most easily on the web. To get a good deal, just make a quick search for a website where you can make a contact lens price comparison and you are on your way. As modern lenses are very soft, surprisingly cheap and handy to use, you are very likely to be satisfied.

The diagnostic tests used to detect cerebrovascular disease include computed tomography, Cn scans, magnetic resonance imaging (MRI), cerebral angiography, and digital subtraction angiography.By using a contrast medium to enhance the view of cerebral vessels, a CT scan helps deter­mine whether a patient’s neurologic changes resulted from an ischemic or hemorrhagic CVA. In an ischemic CVA, the CT scan will show areas of decreased absorption or density. In a hemorrhagic CVA, it will show areas of increased absorption or density. If the patient has had an ischemic CVA, a CT scan can help determine the size and location of a thrombus or embolus. A CT scan also can be used to monitor the effects of a patient’s treatment.

If the patient has experienced a hemorrhagic CVA, the physician may order an MRI to precisely locate the lesion.

Cerebral angiography helps identify the location of a hemorrhagic or ischemic CVA. This test also helps determine the extent of damage to the surrounding cerebral tissue, while allowing direct visualization of the cerebral vascular system. However, cerebral angiography may induce a cerebral embolism, cerebral hemorrhage, or spasm.

Digital subtraction angiography commonly is used with cerebral angiography to better visualize the cerebral arteries by computerized fluoroscopy.

If your patient reports any warning signs of hypertension, suspect urgent hypertension. He may experience a mild headache in the occipital area that’s more severe in the morning. He also may experience dizziness, light-headedness, numbness, weakness, and vision changes. These cerebrovascular signs and symptoms may result from hypertension alone or from hypertension and atherosclerosis. He also may report nosebleeds, which occur as a natural safety mechanism to relieve severe hypertension and prevent cerebral hemorrhage.Your patient with urgent hypertension may experience chest pain, palpitations, dyspnea, paroxysmal nocturnal dyspnea, orthopnea, and edema. These cardiovascular signs and symptoms may develop when his hypertension results from coronary artery disease.Renal signs and symptoms of urgent hypertension include nocturia, polyuria, hematuria, urinary tract infection,· excessive urinary sediment, fatigue, weakness, and muscle cramps. However, these signs and symptoms also may result from kidney damage. If a patient has kidney damage, his condition has worsened from urgent hypertension to emergency hypertension.

Before starting antihypertensive drug therapy, obtain a baseline blood pressure reading from each arm. Then, administer the drug, as prescribed. Use caution when administering it so that your patient’s blood pressure doesn’t fall below the limit of autoregulation. For example, assess your patient for dizziness and light-headedness. If they occur, withhold the drug and notify the physician.Monitor a hospitalized patient’s blood pressure every 1 to 2 hours after administering the first dose. And continue to monitor his blood pressure every 2 to 4 hours, even after it begins to stabilize. Teach an outpatient how to check his blood pressure and when to call the physician. Also, instruct him to check his blood pressure at least once a day until it’s stable, and then to check it once a week.

Monitor your patient for adverse effects of the drug. As prescribed, administer an analgesic for headache and monitor its effectiveness.

Following the physician’s guidelines, adjust the antihypertensive drug dosage as your patient’s blood pressure drops to the target level. Also, assess your patient’s cardiovascular, neurologic, retinal, and renal status after 1 to 4 weeks of drug therapy to evaluate its adverse and therapeutic effects.

Information for Patient

After your patient’s urgent hypertension has subsided, instruct him to adhere to his antihypertensive drug regimen to reduce the risk of future episodes. Teach him the names of all his prescribed drugs and their dosages, expected effects, and adverse effects.

Warn your patient about orthostatic hypotension, a common adverse effect of antihypertensive drugs. Tell him to rise slowly from a sitting position to a standing position and to dangle his feet over the side of the bed for several minutes before getting up. If he becomes dizzy, he should sit or lie down until the feeling passes.

Tell your patient about lifestyle changes that can help prevent a recurrence of urgent hypertension. These changes include avoiding alcohol, stopping smoking, increasing his amount of exercise, doing different types of exercise, performing relaxation and other stress-reduction techniques, and following a low-fat, low-sodium diet. As appropriate, refer him to other health care professionals, such as a dietitian.

Make sure your patient knows the signs and symptoms of hypertension, including headache, dizziness, light-headedness, weakness, VISIOn changes, and chest discomfort. Also, spell out the signs and symptoms of altered organ functioning, such as headache, dizziness, and weakness in cerebrovascular dysfunction; chest pain, palpitations, dyspnea, and peripheral edema in cardiovascular dysfunction; and nocturia, polyuria, and hematuria in renal dysfunction. Instruct the patient to promptly report such signs and symptoms to his physician.

Explain that hypertension can be dangerous even without obvious symptoms. Stress the importance of taking his antihypertensive drug even if he feels well. Tell him to report unpleasant adverse effects, such as beta-blocker-induced fatigue, nightmares, and sexual dysfunction, because the physician may be able to change the prescription.

Discuss the need to have his blood pressure evaluated frequently so that appropriate adjustments can be made in his drug regimen. Confirm that he knows the date and time of the follow-up appointment with his physician and, if appropriate, the date and time of diagnostic testing to evaluate organ function.

After discharge, your patient may need follow­up care by a home care nurse. Explain that the home care nurse will monitor his blood pressure daily for the first few days after therapy begins.

The home care nurse will perform a physical assessment to obtain baseline blood pressure readings. Then she’ll monitor the patient’s blood pressure and report values outside the limits prescribed by the physician.

The home care nurse will confirm that the patient has a follow-up appointment with his physician and ensure that he’s making lifestyle changes, as needed. She’ll also note whether he’s taking his antihypertensive drugs as prescribed. If necessary, she’ll teach him to take his blood pressure. And she’ll remind him to report signs and symptoms of hypertension to his physician.
