How Does Winter Weather Increase Your Risk of Cardiovascular Disease?

Posted on February 1, 2026 by Patrick Hercules

As we get deeper into this winter season, extreme, record-low cold temperatures have brought snow and frigid winds with them. These conditions can severely affect your heart, especially if you already suffer from or are at risk of cardiovascular disease.

The cold temperatures affect the heart by causing blood vessels to constrict, which is the body’s natural reaction to send blood deeper into the body. This doesn’t cause problems for those with healthy arteries. However, if someone has arteries that were narrowed by fatty plaque, cold-related blood vessel constriction can leave them more vulnerable to chest pain or a heart attack. This is especially true when engaging in a strenuous outdoor activity such as walking quickly in a strong wind or shoveling snow, which can commonly trigger a heart attack.

Strenuous outdoor activity in cold weather isn’t the only thing that can put the heart at risk. Cold temperatures also increase the risk of suffering from hypothermia. Hypothermia means the body’s temperature has fallen below 95 degrees Fahrenheit or 35 degrees Celsius, and the body can’t produce enough energy to keep its temperature warm enough. Cold-related blood vessel constriction keeps vital organs warm and helps reduce heat loss. If a person has narrowed blood vessels, the heart must work harder to pump blood through the body, which then raises blood pressure and puts stress on the heart. Hypothermia has several symptoms, including:

Lack of coordination

Slowed reaction time

Mental confusion

Shivering

Sleepiness

Hypothermia can be life-threatening, so it is extremely important to take proper precautions to stay warm by dressing in layers, keeping your head and ears covered, and keeping your hands and feet warm.

If you are going to engage in any strenuous outdoor activities, here are some tips to keep you safe:

Take frequent breaks

Learn the warning signs of a heart attack and listen to your body

Learn CPR

Be aware of the dangers of hypothermia

Don’t drink alcohol before or immediately after a strenuous activity

Consult with your healthcare provider

If you have, or are at risk of developing, or are experiencing symptoms of a heart condition, you should consult a cardiologist to explore the most effective precautions you can take to protect your heart health during the winter season. You can schedule an appointment at Jamaica Hospital Medical Center’s Cardiology Department by calling (718) 206-7100. If you are experiencing an emergency, please dial 911 right away.

When To Worry About Heart Palpitations

Posted on December 9, 2025 by Xavia Malcolm

Heart palpitations are feelings or sensations of a fast-beating, fluttering, or pounding heart. They are felt when the heart beats outside its usual rhythm.

Heart palpitations are common; most aren’t cause for concern. They can be caused by fever, anxiety, stress, fear, drinking alcohol or caffeine, dehydration, menopause, pregnancy, or overactive thyroids. Certain medications and supplements can also cause heart palpitations.

While palpitations are often harmless, they can sometimes be a sign of a serious health problem. Heart palpitations lasting more than a few seconds or minutes can be a sign of arrhythmia or other heart rhythm issues.

Additionally, heart palpitations accompanied by symptoms such as chest pain, shortness of breath, fainting, dizziness, or excessive sweating can be signals of heart failure or other conditions needing immediate care.

A doctor can diagnose heart palpitations by conducting a physical examination, which includes listening to your heart and lungs. Your doctor may also order tests such as an EKG, echocardiogram, or Holter monitoring to check for an irregular heartbeat. They may also review lifestyle factors such as your diet to determine the potential cause of your heart palpitations.

Treatment for heart palpitations depends on the cause. Prescription medications or surgery may be recommended if there is an underlying issue, such as heart disease or arrhythmia. Otherwise, your doctor may suggest lifestyle changes, such as drinking less coffee, quitting smoking, avoiding certain foods, or doing less strenuous exercises to reduce triggers that lead to palpitations.

Magnesium is a mineral that can be found in various foods. It helps support more than 300 different chemical processes throughout the human body, such as:

Muscle function

Regulating blood pressure and blood sugar levels

Promoting energy production

Nerve function and bone health

Mental health

When eating foods containing magnesium, experts recommend consuming between 310 and 420 milligrams (mg) of magnesium per day, depending on age and sex:

Babies 6 months and younger: 30 mg

7 to 12 months: 75 mg

1 to 3 years old: 80 mg

Benefits of Yoga for Heart Health

Posted on October 31, 2025 by Patrick Hercules

There are many aerobic exercises that can increase the heart rate and help prevent or manage heart disease. However, calming exercises such as yoga are good for the heart as well.

Yoga is a mind-body activity that involves moving through a series of body poses and breathing exercises that can improve strength, flexibility, balance, and relaxation. There are dozens of different formats, or practices of yoga, such as hatha, anusara, and ashtanga, that emphasize different focuses, such as toning, strength training, or meditation.

One of yoga’s clearest benefits to the heart is its ability to relax the body and mind. Emotional stress can cause several physical effects, including the release of hormones such as cortisol and adrenaline, which can narrow the arteries and increase blood pressure. The relaxation response that yoga provides not only slows the heart rate and lowers blood pressure; it may also reduce inflammation and promote favorable changes in blood vessel function that protect the heart.

Additionally, practicing yoga can help lower blood cholesterol and blood glucose levels.

As mind-body practices, yoga encourages people to slow down and be more mindful about heart-healthy behaviors, such as eating well and getting enough sleep. These habits, along with positive emotions that some forms of yoga aim to inspire, such as compassion and gratitude, may also help foster cardiovascular health.

Recent studies support the benefits of yoga for heart health. One study has shown that blood measurements and waist circumference, which are signs of heart disease, improved in middle-aged adults with metabolic syndrome who practiced yoga for three months.

Another study has shown that attending slow-paced yoga classes twice a week reduced the frequency of atrial fibrillation episodes in patients with that condition. Additionally, in another report, patients with heart failure who went through an eight-week yoga program showed improvement in exercise capacity and quality of life. They also had lower blood levels of markers for inflammation, which contributes to heart disease.

Research has also indicated that yoga may be a useful tool in helping smokers quit, as smoking is one of the biggest risk factors for heart disease.

If you would like to learn about other ways to be heart healthy, you can schedule an appointment at Jamaica Hospital Medical Center’s Cardiology Department by calling (718) 206-7100.

National Sudden Cardiac Arrest Awareness Month

Posted on October 22, 2025 by Patrick Hercules

October is National Sudden Cardiac Arrest Awareness Month. It is a call to action aimed at raising awareness about the signs and symptoms of sudden cardiac arrest and highlighting its impact on individuals, as well as guiding how to help save lives.

Here are some things to know about cardiac arrest:

· More than 356,000 out-of-hospital cardiac arrests occur annually in the U.S., and nearly 90% of them are fatal

· Cardiopulmonary resuscitation (CPR) can double or triple survival rates, yet fewer than half of victims receive bystander aid

· Sudden cardiac arrest kills one person every two minutes

· About 70% of cardiac arrests happen at home

· An estimated 10,000 cardiac arrests occur at work each year in the U.S.

· Sudden cardiac arrest is the leading cause of death on school campuses

Having a heart attack can increase your risk of experiencing sudden cardiac arrest; however, there are distinct differences between a heart attack and cardiac arrest, their causes, and symptoms.

A heart attack occurs when blood flow to the heart is severely reduced or blocked. The blockage is typically caused by a buildup of fat, cholesterol, or other substances in the coronary arteries.

Sudden cardiac arrest occurs when the heart suddenly stops beating and pumping blood to vital organs.

Signs of sudden cardiac arrest include:

· Unconsciousness

· No breathing or only gasping for air

Many factors can put someone at risk of sudden cardiac arrest, including:

· Family history of coronary artery disease

· Smoking

· High blood pressure and high cholesterol

· Obesity

· Diabetes

· A sedentary lifestyle

· Drinking too much alcohol

· Using illegal drugs such as cocaine or amphetamines

Every second counts in a sudden cardiac arrest. In 95% of sudden cardiac arrest cases, the victim is lost. Survival from an out-of-hospital cardiac arrest greatly depends on nearby loved ones or bystanders promptly calling 911, initiating CPR, and using an automated external defibrillator (AED). For every minute that immediate CPR and use of a defibrillator are delayed, the odds of survival decrease by 10%.

Knowing how to start CPR and how to use an AED greatly increases the chance of survival of a sudden cardiac arrest. The survival rate of sudden cardiac arrest is about 10% for out-of-hospital incidences and 21% for in-hospital events, yet research shows that high-quality CPR has a significant impact on survival outcomes, whether inside or outside the hospital.

Unfortunately, sometimes people refrain from helping someone who needs CPR because of the fear of injuring the person or doing something wrong. Calling 911 and starting chest compressions is better than doing nothing at all because it can help give the person a better chance of survival.

Here is what you can do when someone is in sudden cardiac arrest:

· Call 911 or have someone nearby call 911 immediately. The emergency dispatcher can guide you on what you can do until advanced medical help arrives. This includes how to perform Hands-Only CPR.

· Check to see if the person is breathing or responsive

· Send someone to get the AED

· If the person is not breathing, or gasping for air, and they are not responsive, start CPR immediately. If you don’t know CPR, perform hands-only CPR, pushing hard and fast on the center of the chest

· Use an AED if available. Portable AEDs are available in many public places

Sudden cardiac arrest can affect anyone and everyone. That is why it is important to be educated about sudden cardiac arrest, the warning signs, and how to respond if someone around you goes into cardiac arrest.

Atrial Fibrillation (AFib)

Posted on September 16, 2025 by Xavia Malcolm

Atrial fibrillation (AFib) is a common type of arrhythmia, or heart rhythm disorder. According to the American Medical Association, more than 5 million adults in the United States are living with AFib.

During AFib, the upper chambers (atria) of our heart beat irregularly and rapidly, which may cause blood to pool and clot. This can lead to serious complications such as stroke or heart failure.

The most common cause of AFib is problems with the heart’s structure. Here are other potential causes:

High blood pressure
Thyroid disease, such as hyperthyroidism
Obstructive sleep apnea
Heart diseases such as heart valve disease or coronary artery disease
Infections

Some people have an increased risk of developing AFib more than others. Risk factors include:

Obesity
Lifestyle choices such as smoking or drinking alcohol excessively
Age, especially individuals over the age of 65
A family history of AFib
Having diabetes
Having chronic kidney disease
Having had recent heart surgery

Not everyone who has AFib will notice symptoms. However, in other cases, a person may experience:

Extreme fatigue
Low blood pressure
Shortness of breath
Chest pain
Heart palpitations
Dizziness or lightheadedness

AFib is often discovered during health checkups because not everyone experiences symptoms. You should see a doctor if you are experiencing symptoms such as chest pain, heart palpitations, shortness of breath, lightheadedness, or dizziness.

To diagnose AFib, your doctor will order an electrocardiogram (ECG) to measure the electrical activity of your heart. They may also order additional tests to test conditions that cause irregular heartbeats.

Treatment for AFib can include medications, surgery, or lifestyle changes. To schedule an appointment with a cardiologist at Jamaica Hospital Medical Center, please call 718-206-7100.

Hypertensive Heart Disease

Posted on September 9, 2025 by Xavia Malcolm

Hypertensive heart disease are conditions that develop when chronic high blood pressure, one that is higher than 120/80 mmHg, is left untreated for a long time.

Hypertensive heart disease is a leading cause of illness and death related to high blood pressure. When high blood pressure is not properly managed over time, it puts extra strain on the heart. This can lead to various issues, including damage to the heart, coronary heart disease, and thickening or enlargement of the heart muscles, along with other serious health conditions.

Symptoms of hypertensive heart disease can vary based on the type of heart condition a person has, or the progression of disease; they may include:

Shortness of breath
Chest pain
Pain in the shoulders, neck, or back
Stroke
Sudden cardiac death
Fainting
Dizziness
Fatigue
Swelling of the ankles or legs
A persistent cough

Complications that can result from hypertensive heart disease are:

Heart failure
Stroke
Sudden cardiac death
Arrhythmia

Some people are more likely to develop hypertensive heart disease than others. You have an increased risk if you:

Smoke or use tobacco products
Drink alcohol heavily
Do not exercise regularly
Are taking certain medications
Eat a high-sodium diet
You have a close family member with a history of high blood pressure
Have certain health conditions such as diabetes
Are over the age of 45
Have high cholesterol
Are overweight

Hypertensive heart disease takes years to develop. You can reduce the risk of complications by visiting your doctor regularly. If you are experiencing symptoms associated with hypertensive heart disease, your doctor may order tests such as blood tests, urine tests, an electrocardiogram (EKG), or imaging tests to diagnose the disease.

Treatment for hypertensive heart disease may include medications to control high blood pressure or help your heart in other ways, recommending lifestyle changes, or surgery.

Jamaica Hospital Medical Center is proud to offer a patient-centered environment that consistently provides quality cardiology care. Please call our cardiology department at (718) 206-7100 to make an appointment or learn more about our services.

Cardiovascular Disease in Women

Posted on July 2, 2025 by Patrick Hercules

Cardiovascular disease can be deadly for anyone. However, women face unique risks, largely due to differences in anatomy and hormones. They are more likely to have other heart attack symptoms and have a higher chance of developing symptoms from heart failure.

Over 60 million women (44%) in the United States are living with some form of heart disease. Heart disease is the leading cause of death in women in the United States and can affect them at any age.

There are three types of heart disease. They include:

Coronary artery disease is the most common heart disease, caused by plaque in the walls of the arteries that supply blood to the heart and other parts of the body. After menopause, women are at a higher risk of coronary artery disease because of hormonal changes.

Arrhythmia is a condition in which the heart beats too slowly, too fast, or irregularly. A common example is atrial fibrillation.

Heart failure happens when the heart is too weak to pump enough blood to support other organs in the body. This condition is serious, but it doesn’t mean the heart has stopped beating.

Although some women have no symptoms, other women may experience:

Angina is usually felt as a dull or heavy chest discomfort or ache

Pain in the neck, jaw, or throat

Pain in the upper abdomen or back

These symptoms may happen when you are resting or active. Women may also have other symptoms, including:

Nausea

Vomiting

Tiredness that won’t go away of feels excessive

In some women, the first signs and symptoms if heart disease can be:

A heart attack

Palpitations

A heart attack occurs when blood flow to the heart muscle is reduced or blocked. The amount of damage to the heart muscle depends on the artery and the treatment.

The warning signs of a heart attack include:

Chest discomfort that lasts more than a few minutes or doesn’t go away and returns

Pain or discomfort in the arms, back, neck, jaw, and stomach

Shortness of breath

Other signs can include:

Breaking out in a cold sweat

Nausea

A rapid or irregular heartbeat

Unusual tiredness

Lightheadedness

Medical treatment for a heart attack is based on the type of heart attack and where the blockage in the coronary artery is.

A complete blockage of the artery of the heart is a STEMI or ST-elevation myocardial infarction. A partial blockage is an NSTEMI heart attack or a non-ST-elevation myocardial infarction. The different ways to restore blood flow to the affected heart muscle during a heart attack include:

Clot-dissolving medications

Balloon angioplasty and stenting

Surgery

If you are experiencing an emergency, please call 911 right away. If you are experiencing heart attack symptoms, you can schedule an appointment at Jamaica Hospital Medical Center’s Cardiology Department by calling (718) 206-1700.

Primary Heart Attack Center Certification

Posted on June 4, 2025 by Patrick Hercules

Every year, more than 800,000 people in the U.S. have a heart attack. A heart attack, or myocardial infarction, occurs when blood flow to the heart muscle is reduced or blocked. The blockage is usually due to a buildup of fat, cholesterol, and other substances in the heart’s arteries. The amount of damage to the heart muscle depends on the artery and the treatment.

Most heart attacks are caused by coronary artery disease, which is the most common cause of death in the United States.

The warning signs of a heart attack include:

Chest discomfort that lasts more than a few minutes or doesn’t go away and returns
Pain or discomfort in the arms, back, neck, jaw, and stomach
Shortness of breath

Other signs of a heart attack can include:

Breaking out in a cold sweat
Nausea
A rapid or irregular heartbeat
Unusual tiredness
Heartburn or indigestion
Lightheadedness

Several key factors can affect your risk of having a heart attack. Unfortunately, some heart attack risk factors aren’t things you can modify. They include:

Age and sex
Family history of heart disease
Lifestyle
Certain health conditions

Healthcare providers usually diagnose heart attacks in an emergency room setting. If you have heart attack symptoms, you should undergo a physical exam. A healthcare provider will check your pulse, blood oxygen levels, and blood pressure, and listen to your heart and lung sounds. They will also ask about the symptoms you experienced.

A healthcare provider will diagnose a heart attack using the following testing procedures:

Blood tests
An Electrocardiogram (EKG or ECG)
An echocardiogram
A coronary angiogram
A heart computed tomography (CT) scan
A heart MRI
An exercise stress test
Nuclear heart scans

Treating a heart attack means restoring blood flow to the affected heart muscle immediately. This can happen in various ways, ranging from medication to surgery. Treatment will likely include:

Supplementary oxygen
Medications
Percutaneous coronary intervention
Coronary artery bypass grafting

Although several risk factors for a heart attack can’t be modified, there are many ways to reduce your risk of a heart attack, including:

Scheduling a check-up with a healthcare provider
Quitting tobacco products
Exercising regularly
Eating nutritious foods
Maintaining a healthy weight
Managing existing health conditions
Reducing stress
Taking medications as prescribed
Keeping all medical appointments

Jamaica Hospital Medical Center has been awarded the Joint Commission’s Primary Heart Attack Center certification with a gold seal.

This certification standardizes patient care across hospital settings regarding identification, assessment, monitoring, management, data sharing, and performance improvement for multidisciplinary STEMI heart attack care. Our hospital collaborates with the American Heart Association (AHA) in providing patient-centric cardiac care for all patients, their families, and the community the hospital serves.

The protocols and performance measures related to this designation reduce variances and promote standardization of the best practices in cardiac care. This, in turn, assists in improving clinical outcomes.
