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.

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.

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.

National Afib Awareness Month

Posted on September 20, 2024 by Patrick Hercules

September is National Afib Awareness Month. Afib stands for atrial fibrillation, a type of arrhythmia or abnormal heartbeat. During Afib, the heart’s upper chambers, or the atria, beat chaotically and irregularly. They beat out of sync with the lower heart chambers, the ventricles.

Afib can lead to blood clots in the heart. It also increases the risk of stroke, heart failure, and other heart-related complications.

It usually isn’t life-threatening, but it is a serious medical condition that needs proper treatment to prevent serious health issues.

There are many symptoms of Afib, they can include:

Feelings of a fast, fluttering, or pounding heartbeat
Chest pain
Dizziness
Fatigue
Lightheadedness
Reduced ability to exercise
Shortness of breath
Weakness

People can experience three types of Afib, including:

Paroxysmal Afib
Persistent Afib
Long-standing persistent Afib

The most common cause of Afib is problems with the heart’s structure. Other health problems and heart diseases that can cause Afib include:

A congenital heart defect
Sick sinus syndrome
Obstructive sleep apnea
Heart attack
High blood pressure
Lung diseases, including pneumonia
Coronary artery disease
Thyroid diseases
Infections from viruses

Many factors can increase your risk of Afib, including:

Age
Caffeine, nicotine, or illegal drug use
Drinking too much alcohol
Changes in the level of body minerals
Family history
Long-term health conditions
Obesity
Some medicines and supplements

Healthy lifestyle choices can reduce the risk of heart disease and prevent Afib. Some basic heart-healthy tips include:

Controlling high blood pressure, high cholesterol, and diabetes
Not smoking or using tobacco
Eating a diet that is low in salt and saturated fat
Exercising at least 30 minutes a day at least five days a week
Getting at least seven to nine hours of sleep a day
Maintaining a healthy weight
Reducing and managing stress

Afib is diagnosed when a healthcare provider examines you and asks questions about your medical history and symptoms. Tests may be done to look for conditions causing irregular heartbeats such as heart disease or thyroid disease, including:

Blood tests
ECG or EKG
Holter monitor
Event recorder
Implantable loop recorder
Exercise stress tests
Chest X-ray

The goals of Afib treatment are to reset and control the heartbeat and prevent blood clots. Treatment for Afib depends on how long you’ve had it, your symptoms, and the cause of the irregular heartbeat. Afib treatment can include:

Medications
Cardioversion therapy
Surgery or catheter procedures

If you are experiencing any symptoms of Afib, 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.

Facts About Aspirin Therapy

Posted on April 8, 2021 by Michael Hinck

Daily aspirin therapy is sometimes recommended for people who are at risk for heart attacks or diagnosed with certain heart diseases. While this form of therapy is effective, it may not be the right form of treatment for everyone.

Taking occasional doses of aspirin is typically safe; however, daily use can lead to serious side effects. This is why it is highly advised that you speak with your doctor to determine if this approach is best for you. Serious side effects of aspirin can include:

Gastrointestinal bleeding
A stroke resulting from a burst blood vessel
Allergic reactions

Recommendations for daily aspirin use may vary from person-to-person. Your doctor may recommend this regimen if you have:

Coronary artery disease or atherosclerosis
Had a heart attack
Had a transient ischemic attack or stroke
Had bypass surgery or a stent placement procedure

Your doctor may not recommend daily aspirin therapy if you:

Have a bleeding or clotting disorder
Have bleeding stomach ulcers
Have an aspirin intolerance
Drink alcohol regularly
Are undergoing certain medical or dental procedures

If you are considering daily aspirin therapy, you must consult your physician before you begin. You should inform your doctor about any health conditions or risks you may have that will increase the chances of complications. Provide a list of medications that you are taking, as some may contribute to drug interactions and adverse effects. Based on the current condition of your health, your doctor will advise you as to whether or not daily aspirin therapy is right for you.

February is American Heart Month

Posted on February 1, 2018 by Andrew Rubin

Over 50 years ago President Lyndon B. Johnson proclaimed the month of February to be American Heart Month in order to bring attention to one of the leading causes of death in the United States. This tradition has been carried on by every President since.

Each year over 800,000 lives are taken as a result of heart disease, stroke and other cardiovascular diseases. Every 84 seconds someone in the United States dies from the disease and each year approximately 750,000 people experience a heart attack and of those, about 115,000 will not survive.

The American Heart Association recommends the following behavioral modifications to prevent heart disease:

Avoid smoking
Engage in some form of daily physical activity
Follow a healthy diet
Maintain a healthy body weight
Control cholesterol, blood pressure and blood sugar levels

The death rate from heart disease has been improving slowly over the last decade due to advances in medications, better diagnostic capabilities, and better access to health care, but the statistics are still pretty alarming. If you would like to schedule an appointment with a cardiologist at Jamaica Hospital, please call 718-206-6742.

Jamaica Hospital Supports American Heart Month

Posted on February 14, 2017 by Jamaica Hospital Medical Center

This month, many candy hearts will be exchanged in honor of Valentine’s Day, but Jamaica Hospital Medical Center wants the community to give some thoughts to hearts that are not made of chocolate. That’s because February is also American Heart Month, a special designation intended to remind everyone the importance of heart health.

According to the Centers for Disease Control and Prevention (CDC), heart disease is the leading cause of death in both men and women in the United States and the numbers are increasing. The good news is, by working with your doctor to monitor your condition and by making changes to your lifestyle, heart disease is preventable for most.

Here are some tips to improve your heart health

Schedule an appointment with your doctor, who can conduct a physical evaluation and test your blood pressure and cholesterol levels. If necessary, your doctor can prescribe certain medications to control both.

What Are Your Chances of Developing Heart Disease and Ways to Reduce Risks

Posted on November 1, 2016 by Xavia Malcolm

The term heart disease is used to describe a range of conditions that affect heart function. Some of the most common types of heart disease are coronary artery disease, cardiomyopathy, atrial fibrillation and arrhythmia.

According to the Centers for Disease Control and Prevention (CDC), heart disease is the leading cause of death in the United States. It is the cause of approximately one in every four deaths. These numbers are alarming and may affect you if you are at risk of developing certain heart conditions.

Your chances of developing heart disease are determined by risk factors you may or may not be able to control. Risk factors that you can control (modifiable) are:

Obesity
Diet
Smoking
Lack of physical activity
Excessive alcohol consumption

Risk factors that you cannot control (non-modifiable) are:

Family history
Age
Gender

Whether your risks are modifiable or non-modifiable, the good news is, there are many things you can do to lower the chances or prevent heart disease from developing.

Eating a healthy diet- Eating a moderate and well- balanced diet can help with obesity. Additionally, it can reduce the risk of diseases such as diabetes and hypertension which have been linked to heart disease.
Quit smoking – Smoking damages the lining of the arteries and compromises the function of the heart. Quitting smoking will not only benefit your heart but other organs that can also be affected by tobacco smoke.
Exercising- Exercising as recommended can help regulate blood pressure, keep arteries and blood vessels flexible and improve cholesterol levels.
Moderating alcohol consumption- Excessive alcohol consumption can harm your heart and lead to heart failure, high blood pressure as well as cardiac arrhythmia.

In addition to applying healthy lifestyle changes to your daily routine, it is also helpful to schedule annual physical exams to ensure that your body is functioning normally. To schedule an appointment with a doctor at Jamaica Hospital Medical Center, please call 718-206-7001.

What is Pre-Diabetes?

Posted on January 29, 2016 by Joann Ariola

Are you one of the estimated 54 million people in this country who have pre-diabetes?

Pre-diabetes is a silent health condition that has no symptoms and is almost always present before you develop type 2 diabetes.

It is a condition in which blood glucose levels are higher than normal, but not high enough to be classified as full-blown diabetes. If you haven’t visited your doctor, a good way to see if you are at increased risk for pre-diabetes is to take the American Diabetes Association’s (ADA) Diabetes risk test by visiting

Among those who should be screened for pre-diabetes include overweight adults age 45 and older or those under age 45 who are overweight and who have one or more of the following risk factors:

Habitually physically inactive
Have previously been identified as having impaired fasting glucose (IFG) or impaired glucose tolerance (IGT)
Have a family history of diabetes
Are members of certain ethnic groups (including Asian, African-American, Hispanic or Native American)
Have had gestational diabetes or have given birth to a child weighing more than 9 pounds
Have elevated blood pressure
Have elevated cholesterol
Have polycystic ovary syndrome
Have a history of vascular disease

That said, if you have pre-diabetes, your risk of developing type 2 diabetes can be reduced by a sustained modest weight loss and increased moderate-physical activity, such as walking 30 minutes a day.

Through weight loss and increased physical activity, a dietitian may direct you on how to make food choices that cut down on the amount of fat and carbohydrates by:

Eating more foods that are broiled and fewer foods that are fried
Decrease the amount of butter you use in cooking
Eat more fish and chicken
Eat more meatless meals
Re-Orient your meals to reflect more vegetables and fruit

If you have symptoms such as increased thirst, frequent urination, fatigue and blurred vision, you may have crossed from pre-diabetes to type 2 diabetes.

It’s best to consult a physician if you’re concerned about pre-diabetes or if you notice any type 2 diabetes signs or symptoms. Jamaica Hospital Medical Center’s Ambulatory Care Center is centrally located and has convenient hours. To make an appointment, call 718-206-7001.

The Dangers of Secondhand Smoke

Posted on October 13, 2014 by Xavia Malcolm

Secondhand smoke is a combination of side stream smoke-which comes from the end of a burning cigarette and mainstream smoke-which is exhaled by the smoker. It may seem harmless but the smoke that comes from the end of the cigarette is considered to be even more harmful than the smoke inhaled by the smoker; because there are no filters. Secondhand smoke is harmful to everyone; however, pregnant women, children and partners of people who smoke are the most vulnerable.

There are over 250 harmful chemicals that can be found in the smoke created by tobacco products. Some of these chemicals are carbon monoxide, hydrogen cyanide, ammonia, arsenic, vinyl chloride and formaldehyde. The Environmental Protection Agency categorizes secondhand smoke as a Group A carcinogen; meaning that it can cause cancer in humans.

The more you are exposed to secondhand smoke, the higher your risk of developing diseases and suffering from the health effects. Respiratory symptoms such as wheezing, breathlessness and coughing can be triggered by secondhand smoke. Other harmful health effects include the increased risk of developing heart disease, respiratory disease and strokes.

Pregnant women who consistently breathe secondhand smoke may have miscarriages or give birth to low birth-weight and premature babies. For newborns exposure can escalate the risk of Sudden Infant Death Syndrome. Children can experience increased occurrences of asthma, pneumonia, bronchitis and ear infections.

Secondhand smoke is harmful, despite the level of exposure. Breathing in even a little smoke can be dangerous and the effects on your health can be immediate. There are several ways to reduce the risk of exposure to second hand smoke. You can ask members in your family not to smoke in your home, disallow smoking in your car and choose smoke- free restaurant and indoor places.
