Congestive Heart Failure And Low Blood Pressure

Testing For Heart Disease

Your blood pressure, cholesterol levels, and weight will help your doctor understand your overall risk for heart disease. Your doctor may also recommend other tests to check your heart health, which could include:

• An electrocardiogram to measure your hearts electrical activity. Your heartbeat is the result of an electrical impulse traveling through your heart.
• An echocardiogram to examine how thick your heart muscle is and how well your heart pumps.
• An exercise stress test to see how well your heart functions when its working hard.

If You Notice A Sudden Decline In Blood Pressure

A single lower-than-normal reading is not cause for alarm, unless you are experiencing any other symptoms or problems. If you experience any dizziness, lightheadedness, nausea or other symptoms, its a good idea to consult with your healthcare provider. To help with your diagnosis, keep a record of your symptoms and activities at the time they occurred.

Low Blood Pressure Also Known As Hypotension Is When You Have A Blood Pressure Level That Is Below The Normal Range

If your blood pressure is naturally low, this probably wont cause you any problems and wont need treating. In fact, the lower your blood pressure, the lower your risk of heart disease and stroke.

Low blood pressure can sometimes be caused by medications or can be a sign of another health problem. This can sometimes cause problems such as falls, fainting and feeling dizzy, so it might need looking into and treating. Speak to your doctor or nurse if youre worried about low blood pressure.

How Is Congestive Heart Failure Treated

Doctors will assess the current health status of the patient to establish a baseline, and develop a long-term health plan. This may involve the optimization of medicines and therapies, adding new medication, or possibly enrollment in a clinical trial.

Stabilizing and/or reversing a patients condition often involves long-term, collaborative follow-up with a referring cardiologist or physician.

In serious situations, advanced therapies, which include mechanical solutions, a heart transplant, or hospice, may be offered.

Serious Injuries And Shock

Low blood pressure can also be caused by serious injuries or burns, particularly if you have lost a lot of blood. This can mean that there is less blood being pumped around your body. Low blood pressure can also occur if you go into shock after having a serious injury.

Other kinds of shock are described below.

Anaphylactic shock

Anaphylactic shock, or anaphylaxis, is caused by an allergic reaction to something for example, a wasp sting or a peanut. During an allergic reaction, your body produces a large amount of a chemical called histamine, which causes your blood vessels to widen and leads to a sudden, severe drop in blood pressure.

Cardiogenic shock

Cardiogenic shock occurs when your heart cannot supply enough blood to your body, so your blood pressure drops. This can happen during a heart attack.

What Causes High Blood Pressure

High blood pressure usually develops over time. It can happen because of unhealthy lifestyle choices, such as not getting enough regular physical activity. Certain health conditions, such as diabetes and having obesity, can also increase the risk for developing high blood pressure. High blood pressure can also happen during pregnancy.

You can manage your blood pressure to lower your risk for serious health problems that may affect your heart, brain, kidneys, and eyes.

Blood Pressure And Heart Rate

Blood pressure and heart rate are all regulated by the autonomic nervous system. The autonomic nervous system is a group of muscles and nerves that work independently of the brain and spinal cord. It controls many functions in the body, including heart rate, blood pressure, digestion, breathing, and urination.

There are three main factors that affect blood pressure: gravity, volume expansion , and baroreceptors . Blood pressure is measured using a mercury sphygmomanometer and can be written as systolic or diastolic . For people with hypertension, having a systolic blood pressure greater than 140 mmHg or a diastolic blood pressure greater than 90 mmHg increases your risk of cardiovascular disease.

Low heart rate and low blood pressure: If youre feeling out of breath, lightheaded, or generally unwell, it may be due to low blood pressure. When the blood pressure is too low, it can affect the heart in a number of ways. One of the most common is that the heart will have to work harder to pump blood. This can lead to increased levels of stress and anxiety, as well as fatigue.

Additionally, a low blood pressure can also make it more difficult for the body to get enough oxygen to all its cells. This can lead to a variety of problems, including headaches, dizziness, and confusion. If you think you may have low blood pressure, talk to your doctor about what steps you can take to improve it

What Is The Main Cause Of Congestive Heart Failure

What comes to mind when you think of life-threatening health conditions youd like to avoid? Cancer typically tops the list of diagnoses that most people are afraid of. And while cancer is undoubtedly a horrible disease, its not as common as heart failure. Did you know that more people are hospitalized with heart failure than all types of cancer combined?

Over 6 million Americans live with congestive heart failure, with roughly 650,000 new diagnoses yearly. This debilitating illness is projected to cost the nation $160 billion by 2030. Individually, the average total medical cost for a heart failure patient is approximately $25,000 a year.

While there are many reasons people develop heart failure, it nearly always stems from cardiomyopathy. Therefore, healing from cardiomyopathy and congestive heart failure requires an in-depth understanding of these complex conditions.

What Are Common Congestive Heart Failure Medications

Your doctor may prescribe any of the below drugs, based on your specific heart history:

Diuretics

Also known as water pills, these help rid your body of excess fluids, which eases the strain on your heart.

ACE Inhibitors

These drugs ease the hearts workload by lowering blood pressure, preventing further weakening of the heart. According to a 2017 article published in Pharmacy and Therapeutics, this class of medications is considered the mainstay treatment to reduce mortality among people with heart failure.

Beta Blockers

These medications reduce your hearts rate, which causes your hearts need for oxygen to drop.

Angiotensin II Receptor Blockers

These drugs relax your arteries and veins, lowering blood pressure to make it easier for your heart to pump blood.

Digoxin

This medication strengthens your hearts contractions so that it pumps more blood.

Its important to note that with the exception of diuretics, these medications have been shown to work primarily for people with weaker hearts rather than those whose heart muscles have stiffened . Treatment for this second group focuses instead on managing heart failure symptoms , and addressing any underlying conditions such as high blood pressure, high cholesterol, and atrial fibrillation.

How Do Doctors Diagnose Congestive Heart Failure

When it comes to congestive heart failure, the earlier your diagnosis, the better. Catching this condition in its initial stages allows doctors to begin treating the diseaseand hopefully slow its progression before your heart has suffered too much permanent damage.

So, when it comes to heart failure, what usually brings people to first see a doctor?

• Shortness of breath

• Swelling in the legs

Once there, your doctor will examine you. If you have congestive heart failure, generally your physician will find:

• Low blood pressure

• The sounds of heart murmurs and fluid in the lungs

Treatment Of Congestive Heart Failure

If your ejection fraction is preserved, your doctor will initially prescribe a loop diuretic if necessary to relieve symptoms of fluid overload.

If your ejection fraction is reduced, you will be prescribed a loop diuretic plus an angiotensin-converting enzyme inhibitor followed by a beta-blocker . These two drugs are not usually started at the same time, as you need to adjust to one before starting the other. Once you are stable on one drug, the other is added in. These drugs are designed to relax your blood vessels, lower your blood pressure and slow the heart, Together, they reduce the work load of your heart so it can pump more efficiently.

In addition to the above treatments, other types of drug may also be offered depending on the severity of symptoms and the underlying causes of heart failure. For example, you may also be offered an antiplatelet drug and a statin if needed.

If you have an ejection fraction of less than 35%, you are at greater risk of abnormal heart rhythms and your doctor may talk to you about having an implantable cardioverter defibrillator or cardiac resynchronisation therapy in which a small pacemaker is inserted just below the collarbone to detect and correct heart rate irregularities.

Heart Failuresigns And Symptoms

Heart failure is a condition in which the heart fails to function properly. The terms “heart failure” and “congestive heart failure ” don’t mean that the heart has actually “failed” or stopped but mean one or more chambers of the heart “fail” to keep up with the volume of blood flowing through them.

Heart failure is brought on by a variety of underlying diseases and health problems.

Your condition may involve the left side, the right side or both sides of the heart. Each side has two chambers:

• An atrium or upper chamber
• A ventricle or lower chamber

Any one of these four chambers may not be able to keep up with the volume of blood flowing through it.

Two types of heart dysfunction can lead to heart failure, including:

• Systolic Heart Failure This is the most common cause of heart failure and occurs when the heart is weak and enlarged. The muscle of the left ventricle loses some of its ability to contract or shorten. In turn, it may not have the muscle power to pump the amount of oxygenated and nutrient-filled blood the body needs.
• Diastolic Failure The muscle becomes stiff and loses some of its ability to relax. As a result, the affected chamber has trouble filling with blood during the rest period that occurs between each heartbeat. Often the walls of the heart thicken, and the size of the left chamber may be normal or reduced.

Strengths And Limitations Of This Study

• We have analysed hypotension incidence and risk factors in a large real-world cohort of patients with incident heart failure in UK primary care.

• Data are from The Health Improvement Network database, which has been extensively validated for use in pharmacoepidemiology.

• Since blood pressure is not systematically tested in routine clinical practice, we cannot rule out some detection bias.

• Due to the nature of data collection during routine clinical practice, we were unable to identify reliably the subgroup of cases with orthostatic hypotension, it was unclear if diagnoses of heart failure were made according to guidelines, and data on heart failure severity and ejection fraction were not complete for all patients.

Causes Of Low Blood Pressure

Low blood pressure typically results from one or more of the following:

• Dilation of small arteries

Dilation of arterioles can be caused by

• Spinal cord injuries, in which the nerves that cause the arterioles to constrict are impaired

Low blood pressure also occurs when the nerves that conduct signals between the brain and the heart and blood vessels are impaired by neurologic disorders called autonomic neuropathies Autonomic Neuropathies Autonomic neuropathies are disorders affecting the peripheral nerves that automatically regulate body processes . Causes include diabetes, amyloidosis⦠read more .

When a person quickly moves from a sitting position to a standing position, blood pressure in the blood vessels to the brain decreases, resulting in a temporary sensation of light-headedness or faintness. This is called orthostatic hypotension Dizziness or Light-Headedness When Standing Up In some people, particularly older people, blood pressure drops excessively when they sit or stand up . Symptoms of faintness, light-headedness⦠read more . It can be more pronounced in people who are dehydrated or warm , have certain illnesses, or have been lying down or sitting for prolonged periods of time. Orthostatic hypotension can even cause people to faint. In most people, the body quickly acts to increase blood pressure and prevent the person from fainting.

• New or increasing shortness of breath, especially when lying flat in bed
• A new or worsening cough, especially with pink, frothy or bloody sputum
• New or increasing swelling of your ankles, legs or abdomen
• A weight gain of 3 lbs in one day
• A weight gain of 5 lbs in one week
• An irregular heart rate, a fast heart rate or palpitations
• New or increasing dizziness

Not surprisingly, you are more prone to depression if you have heart failure. If you are feeling low, tell your doctor as treatment will greatly improve your overall quality of life.

Treatment And Medication Options For Congestive Heart Failure

Heart failure is a chronic condition, and there is no cure. However, once youve been diagnosed, there are several things you can do to treat the condition and manage it so that it does not progress. Chief among them are lifestyle changes. That includes exercising and maintaining a heart-healthy diet thats low in saturated fat, trans fats, and cholesterol.

Heart Failure With Preserved Ejection Fraction

Just under half of people with heart failure have a preserved left ventricular ejection fraction . This means that your heart is contracting well but the heart muscle is stiff so the left ventricle does not relax properly between beats. Heart failure with a preserved ejection fraction is particularly common in people with high blood pressure, and those with raised cholesterol, diabetes, obstructive sleep apnea, and in those who smoke.

Stage B Treatment Options

While stage A CHF is managed with lifestyle changes, the treatment plan for stage B typically includes taking medications regularly. People at this stage should still make the same lifestyle changes as those appropriate for stage A. However, your doctor may also prescribe additional treatments such as:

• Angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, if you arent taking any as part of your stage A treatment plan
• Beta blockers if youve had a heart attack and your EF is 40% or lower, if you arent taking any as part of your stage A treatment plan
• Possible surgery or intervention as a treatment for coronary artery blockage, heart attack, valve disease, or congenital heart disease

Iv: Adjust Heart Failure With Reduced Ejection Fraction Treatments According To Clinical Profile

Spreading the medication dose throughout the day may be useful. Other measures such as increased physical activity, cardiovascular rehabilitation, etc., may also help countering the hypotension.

The clinical phenotype of the patient also plays an important role. We propose adjusting the patient’s medication depending on the clinical profile as follows:

• Reduced estimated glomerular filtration rate < 30mL/min/1.73m2 will preferably prompt a decrease in ACEi/ARB or ARNi rather than a decrease in betablockers as the latter is less associated with worsening renal function. MRA discontinuation is considered only as a second step since it only has a limited impact on BP.
• Hyperkalaemia will preferably prompt a decrease in MRAs as they are the medication associated with the most substantial increase in serum potassium.
• Heart rate< 60bpm, glycoside and/or If channel inhibitor should be discontinued as a first step. As a second step, reduction in betablocker dosage, or in the most severe cases, their discontinuation, should be considered.
• In patients with a history of severe arrhythmia, betablockers should be maintained at the highest possible dose a decrease in ACEi/ARB or ARNi should be preferably considered.
• In patients lacking a specific profile, ACEi/ARB, ARNi or betablocker doses can be decreased.
