5 known Disorders of Circulatory System

The circulatory system is very efficient, but it can be affected by many problems and illnesses which may disturb its normal operation and damage the whole body. It is important to know about these diseases to detect, treat and prevent them early enough.

Hypertension A Circulatory System Disorder


Referred to as hypertension a circulatory system disorder, high blood pressure is a condition of the heart characterized by elevated levels of arterial pressure. This silent killer can lead to multiple life-threatening illnesses including heart attack, stroke and kidney failure among others. It is therefore crucial that people learn what symptoms they should be looking for to take action early enough.

Silent Threat: Often Asymptomatic

 Hypertension has no symptoms

The thing about it is that this illness does not show any signs especially when it is still in its early stage hence making people unaware if they are sick or not. Many individuals can live with high BP for many years without feeling unwell at all.

Importance of Regular Blood Pressure Monitoring

Because of this quietness, one’s BP needs to be checked frequently especially if there are risk factors around like; having obese relatives or leading an inactive lifestyle etcetera

Potential Indications and Symptoms

Headaches plus Lightheadedness

Sometimes people with high blood pressure can have headaches, especially in the morning or lightheadedness, particularly when suddenly standing up but these signs are not specific and may be caused by other things.

Visual Changes

High blood pressure may occasionally affect your eyesight which can cause blurred vision or seeing double. If you ever experience such symptoms it usually means that your condition is already very serious thus requiring immediate medical attention.

Chest Pain as well as Shortness of Breath

Severely raised levels of arterial tension have been known to cause chest pains which mimic heart attacks coupled with difficulty breathing; both should be taken seriously enough for them to warrant immediate evaluation by a healthcare provider who will rule out any cardiac complications.

Complicatedness of Neglected High Blood Pressure

Cardiovascular Ailments

Uncontrolled high blood pressure considerably heightens the occurrence of circulatory system diseases like myocardial infarctions, cerebral vascular accidents and congestive cardiac failure. Over time, chronic strain imposed on the heart and vessels may cause injury.

Abnormalities in Kidney Functioning

Hypertension is one of the primary causes of chronic renal disease leading to kidney failure in circulatory system. Prolonged increased force through fragile renal arteries damages them thereby affecting their ability to function well thus resulting in renal complications.


This is a continuous disease in a circulatory system where fats are built up in the walls of blood vessels causing them to narrow and harden. It is known that this condition affects circulation greatly and may result in severe cardiac problems.

Understanding Atherosclerosis

Plaque Formation

Atherosclerosis starts when cholesterol, fats and other substances accumulate along arterial walls. These deposits called plaques can block blood flow over time which weakens vascular performance.

Inflammatory Response

Plaque presence sets off an inflammatory reaction that damages more artery-lining tissues in circulatory system as well as attracts immune cells into them. Chronic inflammation only speeds up the atherosclerotic process instead of reducing it.

Symptoms that are shown by Atherosclerosis

Angina Pectoris

Angina pectoris is a classical sign of atherosclerosis, which implies chest pain or discomfort due to inadequate blood supply to the heart muscle. It can also be felt in the arms, neck, jaw or back.

Peripheral Artery Disease (PAD)

PAD is caused by the narrowing of the arteries in circulatory sytem that send blood to other parts of the body apart from the heart or brain due to atherosclerosis; this leads to symptoms such as leg pain when walking (claudication), cramping and weakness as well as reduced mobility, especially during physical activity.

Coronary Artery Disease (CAD)

When the coronary artery supplying the heart muscles gets affected by atherosclerosis it results in CAD where a person may experience palpitations – awareness of one’s heartbeat, shortness of breath on exertion (dyspnea) or at rest with episodes increasing over time, fatigue which limits daily activities even without any obvious cause and chest pain provoked by emotional stress or physical effort relieved within minutes through rest or nitroglycerin tablets.

2.4 Ischemic Stroke

The risk for ischemic stroke goes high in circulatory system when atherosclerosis damages blood vessels leading to the brain; sudden numbness weakness face arm leg especially on one side only combined with difficulty speaking clearly and understanding others followed shortly thereafter by loss of vision in either eye and both eyes may occur

Complications and Long-Term Results

Cardiac Arrest (MI)

Plaque can sometimes rupture open, forming a blood clot which in turn blocks off the coronary artery without warning resulting in a heart attack or myocardial infarction. Signs may include severe chest pain, dyspnea, vomiting or perspiration.

Peripheral Vascular Disease (PVD)

When the hardening of the arteries is more grave in peripheral blood vessels there may be ischemia that causes damage to tissue thereby predisposing such patients to non-healing wounds like ulcers or gangrene that eventually leads to amputation (loss of limb).

Coronary heart disease (CHD)

Coronary heart disease (CHD) is a frequently experienced heart condition in circulatory system in which the coronary arteries narrow or are blocked entirely, reducing blood flow to the myocardium. In general, this constriction occurs because of plaque – cholesterol, fat, and other substances – building up on the inner walls of these vessels, a process that can lead to various complications such as angina pectoris.* So recognizing what it’s signalling may be critical for timely treatment.

Silent Killer: Asymptomatic CHD

Hidden Illnesses

Sometimes silent coronary heart disease may progress over many years without showing any symptoms in circulatory sytem, especially at its beginning stages. This symptom-free stage can be dangerous as the disease advances and becomes more severe leading to further complications.

Red Lights: Symptoms of Coronary Heart Disease

Chest Pain

The most common sign of CHD is chest pain known as angina pectoris which feels like squeezing or pressure in one’s breastbone region This discomfort often radiates down arms shoulders neck jaw back

Breath Shortness

The blockage of the heart muscles’ blood supply as coronary artery disease progresses causes breath shortness during heightened activity or when emotionally worked up.


If tiredness is persistent and worsens with physical effort, it may signify that the CHD has resulted in decreased cardiac output.

Heart Palpitations

Sometimes, people’s hearts may beat irregularly or flutter thereby making them feel as if their chest is pounding.

Dizziness or Lightheadedness

Fainting spells and dizziness could occur because the brain does not receive enough blood through these narrowed vessels leading to cerebral ischemia.

Acute Events: CHD Complications

Myocardial Infarction (Heart Attack)

A heart attack can occur in circulatory systemwhen a coronary artery becomes completely blocked in circulatory system , leading to intense chest pain, breathlessness, vomiting, sweating and uneasiness. Immediate medical help is essential to reduce injury of the cardiac muscle.

Cardiac arrest

Permanent blockage of the coronary arteries may cause chronic weakness of cardiac muscles over time which results in heart failure whereby it is unable to effectively pump blood throughout the body. t is a circulatory system disorder .Symptoms are characterized by tiredness; shortness of breath; swelling in the legs or abdomen and trouble doing physical activities.

Heart Failure

Heart Failure

Heart Failure is a circulatory system disorder which is a life-threatening condition that occurs when the heart stops pumping blood effectively around the body. Several things can cause this, and they lead to different symptoms, which may have a profound impact on how well people can do things.

Signs and Symptoms


Panting is one of the most frequent signs that someone’s heart is not working right – it might come on with activity but also at rest (orthopnea) or while sleeping (paroxysmal nocturnal dyspnea).

Fatigue and Weakness

If muscles don’t get enough blood due to heart failure, they easily tire even with slight exertion such as getting dressed.

Edema (Fluid Retention)

Edema means swelling caused by too much fluid building up under the skin – often seen in legs ankles or belly but can be anywhere throughout body weight since all-over pump failure leads to poor circulation so water gets stuck

Irregular or Fast Heartbeat (Arrhythmias)

Whenever the heart’s electrical system is interrupted by heart failure, abnormal heart rhythms or arrhythmias occur. These can be described as fluttering in the chest or palpitations marked by rapid heartbeat (tachycardia) and irregular heartbeat (atrial fibrillation).

Persistent Coughing or Wheezing

Coughing or wheezing that lasts for a long time without stopping can be caused by fluid buildup in the lungs which is called pulmonary congestion. This mostly happens when one is lying flat on their back or during physical exertion. Usually worst at night, this symptom makes it harder to breathe well on top of other breathing problems.

Causes and Risk Factors

Coronary Artery Disease

When blood flow to the heart muscle is obstructed by narrow or blocked coronary arteries – most commonly because they have become hardened and narrowed due to atherosclerosis – then heart failure follows suit since it fails to receive proper nourishment through limited oxygen supply from reduced circulation.

High Blood Pressure (Hypertension)

Over time, chronic high blood pressure causes the muscles making up the walls of left ventricles to thicken and become stiff thereby leading to what is known as congestive cardiac failure after some years pass by without any treatment being administered


There are many conditions that can damage the heart muscle, some of which include dilated cardiomyopathy, hypertrophic cardiomyopathy, and restrictive cardiomyopathy; they weaken its pumping ability and may result in heart failure.

Heart Valve Disorders

When valves with hearts go wrong – for example aortic stenosis or mitral regurgitation – blood flow is disrupted inside causing overwork and eventually failure of cardiac muscles.

Peripheral Artery Disease (PAD)

Peripheral Artery Disease

Millions of people worldwide have peripheral artery disease (PAD), which is when arteries that carry blood to the legs and other parts of their bodies become narrow or blocked off completely.It is a circulatory system disorder. It falls under a category known as peripheral vascular diseases. Therefore, recognizing signs early on could be life-saving.

Symptoms of Peripheral Artery Disease (PAD)

Claudication: Leg Pain

Pain during physical activity due to poor blood supply may affect one’s legs – this is called claudication among other names such as fatigue or cramps. The discomfort usually goes away after resting for some time.

Coldness and Numbness

A person diagnosed with PAD might feel coldness or numbness in their feet because not enough oxygen-rich blood reaches those areas thereby decreasing sensitivity to touch there too.

Progress and Complications

Critical limb ischemia

Critical limb ischemia is a condition in circulatory system of severe pain at rest with non-healing wounds and tissue necrosis due to poor blood supply caused by the narrowing of arteries which is far advanced in peripheral arterial occlusive disease (PAD). If left untreated, it results to amputation.

Cardiovascular events risk increment

Peripheral artery disease (PAD) increases one’s chances for having other cardiovascular diseases like heart attack or stroke. This is because the process that narrows blood vessels in legs can as well affect those leading to brain or heart.

Lowered Life Quality

When a person experiences difficulty walking due to pain from PAD-related intermittent claudication, their quality of life suffers greatly since they are unable to move around enough which can result in losing touch with friends thus feeling depressed about everything generally


Disorders of the circulatory system pose a great threat to general health and welfare. If not treated, illnesses like coronary heart disease, hypertension or peripheral vascular disease can have grave outcomes. But many of these conditions can be controlled by timely detection, proper treatment and lifestyle changes which reduce their impact.

This implies that we must make our heart health a priority through routine check-ups, healthy living and sticking to treatment schedules as this will go a long way in helping us prevent them before they become severe. In addition to enhancing well-being, it means that people should also know that by dealing with such problems early enough they can better their lives while ensuring healthier days ahead through management so that they do not lead to complications.

Q. what is Coronary Artery Disease (CAD)?

A. Coronary artery disease (CAD) also known as ischemic heart disease in circulatory system happens when the coronary arteries, which supply oxygen and nutrients to the heart muscle, become narrowed or blocked due to atherosclerosis causing chest pain called angina pectoris or heart attack.

Q. What are some of the causes of high blood pressure?

A. Hypertension or high blood pressure can be caused by age, race, family history; obesity/being overweight; being physically inactive; tobacco use/smoking cigarettes; too much salt (sodium) in diet; stress and certain chronic conditions e.g., diabetes mellitus type 2 (DMT2), kidney disease among others

Q. What are the warning signs for congestive heart failure?

A. Symptoms include shortness of breath with exertion that goes away when you rest; tiredness all the time; swollen ankles, feet or legs (oedema); feeling faint and chest pain due to angina.

Q. How do they diagnose peripheral vascular disease?

A. Peripheral vascular disease is diagnosed based on medical history assessment findings such as intermittent claudication and palpable peripheral pulses but without presence of bruits over arteries distal to site of occlusion; physical examination signs like weak or absent peripheral pulses with cool shiny skin etc.
