With the rising number of cases related to various heart related issues, health anxiety can provoke spiralling thoughts like "what if I am getting a heart attack now" or "can I prevent a heart attack"? If your body is whispering a warning that you can’t afford to ignore it.

In the high-stakes world of heart health, seconds count. Yet many people fail to recognize early warning signs of heart blockages until it's too late. While sophisticated tests like ECGs and angiograms are crucial, what if your own body could offer clues long before a medical emergency unfolds? According to leading cardiac experts, it often does.

So, how can you detect these warning signs without a single test? And what should you do if you're home alone when symptoms strike? A leading heart surgeon breaks it all down for you.

With rising cardiovascular disease rates worldwide—especially among younger adults—being able to identify early red flags of heart blockages from the comfort of your home isn’t just helpful; it could be life-saving. Dr. Jeremy London, a board-certified cardiovascular surgeon from Georgia and a popular voice in the heart health community, is on a mission to teach everyday people how to read their body’s signals and act swiftly in case of a cardiac emergency.

Spotting Heart Blockages Without Medical Tests

Dr. London emphasizes that no blood test or medical scan is a substitute for listening to your own body. “How can you tell that you may have important blockages of the heart arteries without a single blood test, X-ray, or ECG?” he asks. “Well, not surprisingly, you have to listen to your body.”

The human heart often signals distress long before it fails. According to Dr. London, four symptoms deserve immediate attention:

• Chest tightness or discomfort
• Persistent chest pain
• Shortness of breath
• Radiating pain to the jaw or arm

What’s critical, he says, is the pattern of these symptoms. “If these sensations worsen with exertion—like walking upstairs or brisk movement—and ease when you rest, that’s a red flag,” he explains. This pattern suggests the presence of a partially blocked artery struggling to meet the heart’s demand for oxygen during physical activity.

Dr. London likens it to a clogged pipe: “Let’s assume you have a blockage in the artery that feeds the front of the heart. When you move, that area becomes blood-starved and you experience symptoms. When you stop and rest, the demand drops, and so do the symptoms.”

What Are Silent Heart Blockages?

Not all heart blockages present textbook symptoms. Many people, especially women, diabetics, and older adults, may have "silent ischemia"—a form of heart disease without obvious discomfort. Dr. London cautions that while the presence of exertion-based chest pain is concerning, the absence of symptoms does not mean your arteries are clear.

This is why annual health checkups and paying close attention to subtle changes in physical endurance or energy levels are essential, especially for individuals over 40 or with a family history of cardiovascular issues.

What To Do If You Suspect a Heart Attack At Home?

If you feel you are experiencing a heart attack while alone at home is a terrifying scenario but there are crucial steps you can take to protect yourself until help arrives.

1. Call 911 Immediately

Time is the most critical factor. Don't wait for the symptoms to go away. Call emergency services without delay.

2. Make Yourself Easy to Find

“If it's nighttime, turn on all your lights—inside and out—so EMS can identify your home quickly,” says Dr. London. He adds, “Unlock or even better, open your front door. If you become incapacitated, responders won’t have to break in or waste time trying to gain entry.”

3. Sit or Lie Down

This reduces the risk of injury if you faint. A fall during a cardiac event could compound the danger with head trauma or bone fractures.

4. Inform Someone You Trust

If you can, alert a friend or family member. Not only can they come to assist, but they can also inform paramedics of your medical history, medications, or allergies if you’re unable to speak.

Dr. London strongly encourages households—especially those with elderly members or individuals at high risk of heart disease—to create a personalized emergency plan. “Preparation can save lives,” he says. Your plan should include:

• Emergency contact numbers
• Access to any prescribed medications like aspirin or nitroglycerin
• Easy access to doors and visible house numbers
• A buddy system or wellness check arrangement if living alone

Can You Prevent Blockages In Your Heart?

Spotting symptoms early is essential but preventing blockages in the first place is even better. A heart-healthy lifestyle can significantly reduce your risk:

Diet: Emphasize fiber-rich, whole foods while limiting saturated fats and processed sugar.

Exercise: Aim for at least 150 minutes of moderate activity per week.

Regular checkups: Keep tabs on cholesterol, blood pressure, and glucose levels.

Stress management: Chronic stress can raise cortisol and blood pressure, increasing cardiovascular risk.

Quit smoking: Tobacco use narrows arteries and increases plaque buildup.

Heart blockages often give off clues but only if we’re paying attention. Dr. Jeremy London’s insights offer a wake-up call to listen more closely to what our bodies are saying, especially during moments of physical exertion or unexplained fatigue.

Learning how to detect and respond to potential heart issues while at home doesn’t replace professional medical care but it can bridge the critical minutes between symptom onset and lifesaving intervention.

Tooth disorders led to an average of nearly 1.94 million emergency department (ED) visits each year between 2020 and 2022, according to a recent data brief by the National Center for Health Statistics. The data, drawn from the National Hospital Ambulatory Medical Care Survey, highlights a significant burden on emergency care systems across the United States.

Who’s Going to the ER for Tooth Problems?

The analysis, led by Susan M. Schappert and Dr. Loredana Santo, revealed that adults aged 25 to 34 accounted for the highest proportion of these emergency visits—29.2 percent. While tooth disorders represented 1.4 percent of all ED visits, that translated to about 59.4 visits per 10,000 people annually.

When broken down by race and ethnicity, White non-Hispanic individuals made up the largest share, followed by Black non-Hispanics and Hispanics. Medicaid was noted as the primary expected source of payment, suggesting that many patients with limited access to dental care rely on emergency services for dental issues.

Another notable trend: the prescription of opioids for dental pain relief has dropped significantly. From 2014 to 2016, 38.1 percent of patients were prescribed opioids as the sole form of pain relief. By 2020 to 2022, that figure had fallen to 16.5 percent, indicating a shift in pain management strategies amid growing awareness of the opioid crisis.

What Are Tooth Disorders?

Tooth disorders include a range of conditions that affect the teeth, such as:

• Tooth decay – Damage to the tooth's surface, often leading to cavities
• Abscess – A pus-filled infection, often painful and serious if left untreated
• Impacted teeth – Commonly wisdom teeth that haven’t broken through the gums
• Malocclusion – Misaligned teeth that may affect chewing or speech
• Tooth injuries – Including chipped, cracked, or broken teeth

What Causes These Problems?

Tooth disorders can be caused by various factors, including:

• Poor oral hygiene, such as not brushing or flossing regularly
• High sugar consumption, which can accelerate decay
• Accidents or injuries
• Genetic conditions or developmental issues

Symptoms to Watch Out For

Different tooth problems come with different symptoms, but common warning signs include:

• Tooth pain or sensitivity
• Abnormal color or shape of the tooth
• Swelling or pus around the gums
• Worn-down teeth from grinding or misalignment

Diagnosing and Treating Tooth Disorders

Dentists typically diagnose tooth disorders through a physical examination, using dental instruments and sometimes X-rays. Depending on the issue, treatments may include:

• Fillings for cavities
• Root canals for deeper infections
• Tooth extractions for severely damaged or impacted teeth
• Orthodontic treatment for misalignment

Can They Be Prevented?

Yes—most tooth disorders are preventable with good oral hygiene. Experts recommend:

• Brushing twice daily with fluoride toothpaste
• Flossing or using an interdental cleaner daily
• Limiting sugary foods and drinks
• Avoiding tobacco products
• Seeing a dentist regularly for check-ups and cleanings

Why This Matters

Dental care often gets sidelined, especially for those with limited access to regular services. Yet, as the numbers show, ignoring tooth problems can lead to costly emergency visits and long-term health risks. Promoting awareness and access to preventive care is key to reducing this burden—not just on individuals, but on emergency care systems too.

Deaths due to alcohol-associated liver disease (ALD) are climbing at an alarming rate across the United States, with certain groups being disproportionately affected. A new study published on June 11 in JAMA Network Open found that ALD-related deaths rose nearly 9% each year between 2018 and 2022—more than double the rate of increase seen from 2006 to 2018.

Experts believe this sharp uptick is partly linked to increased alcohol consumption during the COVID-19 pandemic. Other contributing factors include chronic conditions like obesity and hypertension, which can worsen liver health. “It puts numbers to what we’re seeing in the hospital, in the clinic,” said Dr. Brian Lee, a liver specialist at Keck Medicine of USC, in a report to STAT News.

Worsening Trends Among Women and Indigenous Populations

While men still experience more deaths from ALD—17 per 100,000 in 2022—women’s death rates have risen more sharply. In 2022, 8 out of every 100,000 women died from alcohol-related liver disease, a significant jump from 3 per 100,000 at the beginning of the study period. Women’s mortality rate grew at approximately 4.3% per year—almost twice the rate seen in men.

The study also revealed a devastating impact on Indigenous communities. American Indian and Alaska Native adults had the highest cirrhosis death rate in 2022, at 33 per 100,000 people. Additionally, alcohol-associated hepatitis deaths in these groups more than doubled between 2010 and 2022.

Dr. Nasim Maleki, a psychiatry professor at Harvard Medical School, noted that although the pandemic has eased, its long-term effects—particularly in marginalized communities—are still unfolding. “The pandemic itself came under control, but the disparities that came with it continued and lingered,” she said.

Young Adults at Higher Risk Than Before

A particularly troubling trend is the increase in alcohol-associated hepatitis deaths among people aged 25 to 44. This condition can develop quickly and is marked by symptoms like fatigue, jaundice, and liver pain—even in individuals who haven't been heavy drinkers for long.

Liver experts warn that the worst effects of pandemic-related drinking might still be ahead. “Alcohol-related cirrhosis takes time to develop. So we may not see the true extent of the consequences until five, probably 10, years from now, which is very concerning,” said Dr. Robert Wong of Stanford University.

Why Women Face Unique Risks

One reason for the sharper rise among women lies in biology. Cisgender women metabolize alcohol differently than cisgender men, which means their organs may suffer more damage from lower levels of alcohol consumption over time. That’s why current federal guidelines recommend no more than one alcoholic drink per day for women, compared to two for men.

“You’d be surprised by how shocked people are when they hear that drinking more than two drinks per day is considered heavy drinking by federal definitions,” Dr. Lee added.

Public Health Response and the Way Forward

In 2021, over 12,000 deaths from “unspecified liver cirrhosis” were linked to excessive drinking, although that may not always be evident from death certificates. Marissa Esser, who previously led the alcohol program at the U.S. Centers for Disease Control and Prevention, highlighted this hidden toll before the program was disbanded earlier this year.

The American Medical Association is now calling for more public education on alcohol’s risks, including its link to breast cancer. It is also urging clearer labeling on alcoholic beverages to help consumers make informed choices.

Though some data suggests a slight drop in alcohol use since its peak in 2020, it remains uncertain whether this will reduce deaths in the coming years. For now, ALD continues to be the leading reason for liver transplants in the U.S., and alcohol-associated hepatitis is the fastest-growing cause.

As the summer sun rises high, everyone anticipates relief from seasonal sniffles. Yet increasingly, more and more people are falling ill with cold-like symptoms in warmer weather too. The twist? A new Covid strain—NB.1.8.1—is spreading low-key around the world, from Asia to America and the UK. The challenge is distinguishing between a run-of-the-mill summer cold and a COVID-19 infection.

Typically, respiratory illnesses peak in the colder months when more time is spent indoors and dry air allows viruses to be more easily susceptible. Summer, however, is not virus-free. Parainfluenza virus Type 3, enteroviruses, adenoviruses, and even rhinoviruses are still causing issues in warmer climates. Social events, travel, lack of rest, more alcohol consumption, and air conditioning all set the stage for infections.

Complicating the situation further this summer is the discovery of the NB.1.8.1 Covid strain. Although the World Health Organization (WHO) only recently started monitoring it, scientists are closely monitoring its trajectory and possible implications.

Initially discovered in China in January 2025, NB.1.8.1 has a number of mutations that have caught the eye of the world's health authorities. The good news? There is as yet no evidence to suggest it results in more serious disease. In fact, U.K. Health Security Agency statistics indicate a modest rise in COVID cases with 5.2% of patients positive—up from 4.5% last week.

To date, just 13 of the confirmed NB.1.8.1 cases in the U.K. have been sequenced, the majority of them in April and May. While uncommon at present, the fact that it shares features with other variants of Covid means caution is still crucial.

Summer Colds vs. NB.1.8.1 Covid: Why It's Hard to Tell the Difference?

Both summer colds and Covid-19 have common symptoms such as:

• Sore throat
• Nasal congestion or runny nose
• Fatigue
• Muscle aches
• Nausea or vomiting

However some symptoms will tend more towards Covid, such as:

• Fever or chills
• Shortness of breath
• Loss of taste or smell, new
• Gastrointestinal illness such as diarrhea

There is no guaranteed way to tell the difference between a summer cold and Covid without doing a diagnostic test. Mild COVID-19 symptoms are easily mistaken for other seasonal viruses.

What Exactly Is a Summer Cold?

Colds—seasonal or not—are viral illnesses that are transmitted by respiratory droplets, fomites (contaminated surfaces), or close proximity. The main culprits are rhinoviruses, especially during the winter months, but the warmer months experience an upsurge in viruses such as parainfluenza, enteroviruses (coxsackie and echovirus), and adenoviruses.

Summer activities—weddings, concerts, holidays—promote intimate contact between groups, and typical summer behaviors such as drinking, bad sleep, and poor diet compromise immune systems. Air conditioning units, by dehydrating nasal passages, also impair the body's resistance to viral invaders.

The Centers for Disease Control and Prevention (CDC) urges anyone with cold-like symptoms to monitor closely. Covid-19 symptoms can appear two to 14 days after exposure and vary from mild to severe. The virus can be contagious two days before symptoms emerge and up to 10 days—or more—in immunocompromised individuals.

If you’re feeling unwell, the best course of action is to:

• Stay home and rest
• Wear a mask if around others
• Get a COVID-19 test
• Talk to your healthcare provider

Timely treatment, such as antiviral therapy with Paxlovid, is ensured through accurate diagnosis, particularly among high-risk individuals.

Can Vaccines Protect Against NB.1.8.1?

While a newer vaccine aimed at fall variants is being developed, the existing vaccines remain protective against NB.1.8.1. The variant is of the "drifter" type from the Omicron lineage, which indicates earlier immunity could still help prevent severe disease.

Dr. Aaron Chen, a Johns Hopkins University virologist, observes, "Although mutation is unavoidable, current vaccines remain effective in preventing hospitalization and complications from new variants, such as NB.1.8.1."

How To Avoid Getting Sick This Summer?

There's no surefire way to completely avoid viruses, unfortunately. But here are some practical tips from experts:

• Drink plenty of water and moderate your booze
• Consume a nutrient-dense diet full of fruits, vegetables, and lean proteins
• Get good rest and reduce stress levels
• Clean those surfaces that are touched most often such as airplane trays, phones, and exercise equipment
• Supplement with vitamin D if one is deficient since it enhances immune function
• Wash hands frequently, do not share food or beverages, and wear a mask in public indoor areas

What If You Do Get Sick?

Most people recover from summer colds and mild Covid-19 at home. Supportive care—hydration, over-the-counter pain relief, and rest—is typically enough. Nasal decongestants and lozenges can ease symptoms, while more serious or persistent cases warrant medical consultation.

If you suspect Covid, getting tested is crucial—not only for your health but for the wellbeing of those around you.
