Cardiac care for the elderly: managing cardiovascular risks and heart-protective habits

The heart is the heart of life. It continuously delivers nutrients, oxygen, and hormones to all cells in the body and removes metabolic waste such as carbon dioxide, while helping the body cope with activity, exercise, and stress. As we age, the heart and blood vessels undergo natural changes—the heart muscle and arteries become harder and thicker, making it more strenuous for older adults to handle strenuous activity and increasing their risk of heart problems.Hypertension, coronary heart disease, heart failureIssues such as... The good news is:Cardiovascular health can be improved through lifestyle habits, and it's never too late to start at any age.However, if you experience any signs of a heart attack, please call emergency medical services immediately.

1. Changes in the heart and blood vessels with age

The heart is a muscle about the size of a fist, responsible for pumping blood throughout the body: the right side sends blood to the lungs to absorb oxygen, and the left side then sends the oxygenated blood via arteries to various organs. According to...The National Institute on Aging (NIA)Normal aging brings about some changes to the heart and blood vessels:

• As people age, the heart experiences stress during activity or when compressed.It is difficult to increase the jumping speed.(However, resting heart rate generally does not change much).
• The heart muscle may thicken and the blood volume in the chambers may decrease slightly, increasing the risk of arrhythmia and other heart rhythm problems.
• Heart valves may thicken and harden, affecting blood flow;
• Decreased elasticity of large arteries (arteriosclerosis)High blood pressureMore common.

These changes can increase the risk of heart disease and related problems. Therefore, older adults should have regular checkups.Blood pressure and cholesterolIt is extremely important, even if you feel you are healthy.

2. Common Heart Problems and Their Causes in the Elderly

According to NIA andThe UK National Health Service (NHS)Common heart problems among the elderly include:

• Hypertension (caused by arteriosclerosis):It becomes more common with age, often without symptoms, but increases the risk of stroke, heart disease, kidney disease, and other ailments.
• Coronary artery disease (CAD):Coronary arteries narrow due to fatty deposits (plaque), leading to insufficient blood supply to the heart muscle. This process is called…AtherosclerosisIt must be emphasized that:Although arteriosclerosis is common, it is not part of normal aging.。
• Heart failure:An insufficient heart pumping of blood to meet the body's needs can be caused by long-term hypertension, coronary heart disease, diabetes, etc. Common symptoms include shortness of breath and swelling of the feet, ankles, and abdomen.

It is worth noting thatEarly-stage heart disease often has no obvious symptoms.Some people don't discover their condition until they have a heart attack or other problems, which is why regular checkups are so valuable. In late adulthood, some early comorbidities (such as chronic obstructive pulmonary disease, atrial fibrillation, peripheral vascular disease, osteoarthritis, osteoporosis, mood problems, and neurological disorders) can also increase the burden of chronic heart problems.

How does atherosclerosis develop?

The inner wall of the coronary arteries is formed by the accumulation of substances such as fat and cholesterol.plaqueThis process often begins slowly in youth, progresses with age, and typically brings significant risks after the age of 50 to 60.Smoking, high cholesterol, high blood pressure, diabetes, obesity, and unhealthy lifestyle habitsAll of these can accelerate the process. When arteries supplying the heart or brain are blocked by plaque, it can trigger...Heart attack or stroke。

3. Understanding a Heart Attack: Symptoms and Immediate Treatment

A heart attack (myocardial infarction) occurs when the blood supply to the heart muscle is cut off, depriving the heart muscle of sufficient oxygen and nutrients. Coronary artery disease cannot be "cured," but treatment can control symptoms and reduce the chance of a heart attack.

Common symptoms of a heart attack

依NHSWith NIA, possibly including:

• Chest pain, pressure or squeezing sensationIt can spread to the arms, neck, jaw, and back;
• Rapid breathing;
• Sweating profusely, pale or grayish complexion;
• Nausea, vomiting, upper abdominal discomfort, or a burning sensation like "indigestion".

Distinguishing between:Heart attackIt is due to obstructed blood supply to the myocardium;cardiac arrestThis is a sudden cardiac arrest that causes loss of consciousness; the two require different treatment. If you have any questions about your heart condition, please consult your doctor.

4. Exercise and cardiovascular function

Staying active is a great way to slow down muscle loss and maintain cardiovascular endurance. Regular aerobic exercise helps improve several cardiovascular risk factors, increases survival rate and quality of life, and also improves physical function by increasing muscle strength, muscle mass, and bone density; conversely,Lack of physical activity is associated with an increased risk of cardiovascular death.In addition to improving physical function, exercise can also help improve mood, activity level, and mental state, reducing the adverse effects of prolonged sitting.

依NIA與World Health Organization (WHO)It is suggested that the elderly can go toAt least 150 minutes of moderate-intensity activity per weekWith the goal, and in coordination
Strength (resistance) training – both aerobic exercise and resistance training are good for the heart; most importantly, “get moving”, any activity is better than no activity at all.

As forCardiac Rehabilitation ProgramThis is generally a professional recovery plan referred and assisted by a doctor after a heart attack, angioplasty, or heart surgery; it is not a "cure-all" that one can choose on their own. When choosing an exercise program, seniors should first consider their age and health condition.Consult a doctor firstThen decide on the appropriate type and intensity.

5. Omega-3 and Heart Health

Omega-3 fatty acids (ALA, EPA, DHA) are important components of cell membranes.Heart, blood vessels, lungs, immune and endocrine systemsBoth have their functions. ALA mainly comes from plants (flaxseed, soybean, canola oil), while EPA and DHA come from fish and seafood.

according toUS NIH data：

• 把Fatty fish and seafoodIncorporating a balanced diet can help maintain heart health and reduce the risk of some heart problems.
• Obtaining more EPA and DHA from food or supplements canLowering triglycerides；
• The American Heart Association (AHA) recommends consuming one to two servings of seafood per week.People with pre-existing heart disease can take about 1 gram of EPA plus DHA daily under the guidance of a medical professional (oil-based fish is preferred, but supplements are also an option).

Omega-3 can be found in a variety of foods, including walnuts, canola oil, soybeans, and grains, pasta, and dairy products fortified with Omega-3.

6. Heart-protecting habits and diet

Another key to controlling cardiovascular risk is reducing harmful intake and establishing healthy habits.WHONHS and NIA:

• Fat selection:Reduce saturated fat andTrans fatsThese foods can raise "bad" cholesterol (LDL), a risk factor for arterial plaque; they should be replaced with unsaturated fats (vegetable oils, nuts, fish). Reducing processed and fried foods and reading packaging labels to avoid hydrogenated oils are practical practices.
• Dietary fiber and carbohydrates:Consume plenty of whole grains and dietary fiber (WHO recommends at least 25 grams per day for adults, from vegetables, fruits, legumes, and whole grains). Carbohydrates generally account for about 451 TP4T to 751 TP4T of total daily energy, mainly from unrefined whole grains.
• Reduce salt intake:Older adults are more sensitive to salt, and excessive salt intake can raise blood pressure; the WHO recommends a daily salt intake of less than 5 grams (about one teaspoon).
• Controlling sugar intake:Free sugars should be less than 101 TP 4T of total daily energy.

Smoking and alcohol

• Smoking:Smoking accelerates coronary atherosclerosis, promotes fat deposition and plaque growth, and is a major preventable cause of cardiovascular disease. Quitting smoking (even later in life) can improve health and reduce the risk of heart disease and stroke.
• Alcohol:Excessive alcohol consumption increases the risk of high blood pressure.The NHS recommends that adults consume no more than 14 units of alcohol per week regularly and try to abstain from alcohol for several days; the NIA further reminds older adults to...Drink as little as possible or not at all.This is because alcohol can worsen existing health problems and may have dangerous interactions with medications.
  (The previous article stating that "12 ounces of beer per day for women and 24 ounces for men can prevent high blood pressure" is incorrect and dangerous: alcohol itself raises blood pressure and is not a means of protecting the heart. This has been corrected.)

7. Selection and Product Recommendations

If you wish to use nutritional supplements as part of your daily heart health maintenance, please check whether the product clearly states this information.Ingredients, content, dosage form and third-party testingCommon cardiovascular-related options includeOmega-3 fish oil (EPA/DHA)When purchasing fish oil, pay attention to the actual content of EPA and DHA, rather than just looking at the "mg count of fish oil".

However, it must be emphasized that:Supplements cannot replace medication or regular treatment.Supplements cannot replace a balanced diet and exercise. If you are taking anticoagulants, blood pressure medication, or cholesterol-lowering medication, or are preparing for surgery, be sure to consult your doctor or pharmacist before supplementing.
