New York: Survival rates from cardiac arrest decrease the higher up the building a person lives, warns a new study.
“Cardiac arrests that occur in high-rise buildings pose unique barriers for 911 — the emergency telephone number for the North American Numbering Plan, initiated first responders,” said lead author Ian Drennan, researcher with Rescu at the St. Michael’s Hospital in Ontario, Canada.
Building access issues, elevator delays and extended distance from the emergency vehicle to the patient can all contribute to longer times for 911-initiated first responders to reach the patient and start time-sensitive, potentially life-saving resuscitation, the researchers explained.
The number of people living in high-rise building grew by 13 percent in Toronto, in 2006- 2011.
Many of those people are older, with higher rates of serious medical issues and higher risk of cardiac arrest.
The researchers found that only 3.8 percent adults survived, out of a data of 8,216 adults (from January 2007 to December 2012), after suffering an out-of-hospital cardiac arrest and were treated by 911-initiated first responders in Toronto and Peel Region.
Survival was 4.2 percent for people living below the third floor and 2.6 percent for people living on or above the third floor.
Survival above the 16th floor was 0.9 per cent (of 216 cases, only two survived). There were no survivors to hospital discharge of the 30 cardiac arrests above the 25th floor.
“Patients who survived tended to be younger, their cardiac arrest was more often witnessed by bystanders, and bystanders were more likely to perform Cardiopulmonary resuscitation (CPR) — a lifesaving technique useful in especially in heart attack,” Drennan said.

Beijing, October31’2017: If you enjoy eating spicy Chinese food, there are greater chances that you would crave less for salt and have lower blood pressure, potentially reducing the risk of heart attack and stroke, new research suggests.
“Previously, a pilot study found that trace amounts of capsaicin, the chemical that gives chili peppers their pungent smell, enhanced the perception of food being salty,” said senior study author Zhiming Zhu, Professor at the Third Military Medical University in Chongqing, China.
“We wanted to test whether this effect would also reduce salt consumption,” Zhu added.
The study enrolled more than 600 Chinese adults and determined their preferences for salty and spicy flavours. Researchers then linked those preferences to blood pressure.
The findings, published in the journal Hypertension, showed that compared to those who least enjoyed spicy foods, participants with a high spicy preference had lower blood pressure and consumed less salt than participants who had a low spicy preference.
They also used imaging techniques to look at two regions of the participants’ brains — the insula and orbitofrontal cortex — known to be involved in salty taste.
The researchers found that the areas stimulated by salt and spice overlapped, and that spice further increased brain activity in areas activated by salt.
This increased activity likely makes people more sensitive to salt so that they can enjoy food with less of it, the researchers said.
“If you add some spices to your cooking, you can cook food that tastes good without using as much salt,” Zhu said.
“Yes, habit and preference matter when it comes to spicy food, but even a small, gradual increase in spices in your food may have a health benefit,” Zhu said.(IANS)
A recent study shows that the survivors may be at an increased long-term risk of asthma, other similar respiratory diseases, and heart attack
The findings indicate that intense exposure on a single day – the first day of the disaster – contributes substantially to the risk of developing chronic conditions
The authors used data from the WTC Health Registry cohort to examine the long term health effects of acute exposure to the dust cloud or physical injury caused by the terrorist attack
Washington, July 18, 2017: The terrorist attacks on the World Trade Centre on September 11, 2001, have made the accident a historical event, having left behind scars that are much more than just skin-deep. A recent study shows that the survivors may be at an increased long-term risk of asthma, other similar respiratory diseases, and heart attack.
The association between physical injury or acute exposure to the dust cloud on the morning of September 11, 2001, and chronic diseases up to ten to eleven years later (2010-2012) were examined and analyzed by researchers at the New York City Department of Health and Mental Hygiene.
According to the corresponding author Robert Brackbill, the findings indicate that intense exposure on a single day – the first day of the disaster – contributes substantially to the risk of developing chronic conditions. He also mentioned, “Continued monitoring of people who were present in the vicinity of the World Trade Centre on 11th September by medical providers is warranted for the foreseeable future.”
The researchers observed that the number of types of injuries, such as fractures, head injuries, or sprains, a person sustained on 11th September 2001 was associated with an increased risk of angina or heart attack in a dose-dependent manner. This means that the risk of having angina or a heart attack went up with every additional injury type.
According to ANI, exposure to dust, PTSD and being a rescue worker, as well as current smoking were associated with a higher risk of non-neoplastic lung disease (lung conditions not involving tumors) other than just asthma. Dust exposure, on its own, was associated with an increased risk of asthma. But none of these risk factors were associated with a higher risk of diabetes.
Out of the total number of 8,701 people who were a part of this study, 41% had been intensely exposed to the dust cloud, 10% had a single injury, 2% had two types of injury and 1% had three or more.
In the survey, the researchers also noticed 92 incident cases of heart disease, 327 new cases of diabetes, 308 cases of asthma, and 297 cases of non-neoplastic lung disease among 7,503 area workers, 249 rescue workers, 131 residents and 818 bystanders – the most heavily exposed groups.
The authors used data from the WTC Health Registry cohort to examine the long term health effects of acute exposure to the dust cloud, or physical injury caused by the terrorist attack. The WTC Health Registry is responsible for monitoring the physical and mental health of 71,431 persons exposed to the 9/11 attacks.
In the study, a lack of specific information on the severity, location, and treatment of injuries, as well as on the circumstances in which they were sustained meant that the number of types of injuries was used as a proxy measure of injury severity. However, the authors mentioned that it has been shown by previous researchers that more than one type of injury can be associated with increased risk of death and longer stays in the hospital.
The study has been published in the Injury Epidemiology journal.

Jan 10, 2017:According to the WHO, over 17.3 million people die every year from the heart attack and stroke. And if we look at the Indian context, things don’t look bright either. Unhealthy eating habits and sedentary lifestyle are some major factors why men and women are at the risk of developing cardiovascular diseases early on in life.
At an event to commemorate the ‘World Heart Day’, several health experts across the country stated that there are several instances of individuals in the late 20s and early 30s being admitted to hospitals for the treatment of ailments related to the heart. If this trend continues, then the country would transform into the ‘Heart Disease Capital’ of the world in the near future. Heart problems are critical, and the risk can be averted by resorting to the healthy lifestyle.

Say No to Smoking
If you are a smoker, it’s time to ditch the habit. It is a well-established fact that cigarette smoking is linked to lung cancer and respiratory tract disorders. But, did you know that this habit can also put you at the risk of heart diseases? Here’s how cigarette smoking can lead to heart diseases –
Deprives heart from receiving enough oxygen
Shoots up the blood pressure
Increases heart rate
Causes clots in the blood which can cause heart attack and stroke
Damages blood vessels of the heart
While most people are aware of the hazardous effects of smoking, giving up on this habit is not easy. One has to stay determined. You could also consult a doctor or physician for medications or techniques to fight the urge to smoke. Try using nicotine gums and patches, which have proved to be effective for other people.
Stay away from Junk Food
Those with a family history of coronary heart diseases should particularly be careful about what they eat. Consuming trans-fat and sodium-laden food can build up fat deposits in the coronary arteries that can further lead to heart failure and even stroke. Therefore, bid adieu to pre-packaged convenience food and say hello to the following dietary choices that promote good health –
Increase the intake of dietary fiber like whole grains, nuts, seeds, legumes, etc.
Have a generous portion of fruits and vegetables, especially those with a low glycemic index like apples, cherries, tomatoes, lettuce, cauliflower, bell pepper, bottle gourd, etc.
Include supplements like fish oil and Omega fatty acids which help control cholesterol and high blood pressure.
Consume enough water. Health experts point out that consuming an adequate amount of water per day can significantly reduce the risk of heart diseases. Studies have also indicated that not drinking enough water can lead to dehydration, thereby elevating the risk of heart diseases, such as, whole blood viscosity, plasma viscosity, hematocrit and fibrinogen. Therefore, invest in a good water purifier, such as a Kent water filter that gives out pure drinking water without leaching out essential natural minerals. This way you will have access to clean and fresh drinking water always.

30 minutes of a moderate aerobic workout for five days a week or 25 minutes of a high-intensity aerobic exercise for at least three days in a week is essential.
Muscle or strength training for a minimum of 2 days in a week is also advantageous for weight loss along with many health benefits.
Therefore, put on your workout gear and chalk out a fitness goal. People who are over-weight should start with a moderate workout, and slowly transcend to a more vigorous routine. Group classes for aerobics and Zumba are fun to attend, and will also keep you motivated. Look out for unique exercise options in your neighbourhood. These days, several social apps will connect you with people who are on a similar mission for good health. It’s always better to work out with a buddy than alone. You can also consider joining a running group. It is a great way to reach your fitness goal and strike new bonds of friendship, at the same time.
Correct your Sleep Cycle
Not many people realize, but there is a strong correlation between the lack of sleep and an increased risk of heart diseases. Sleeping for less than six or seven hours a day is not good for heart health.
The shorter spell of sleep shoots up the blood pressure and increases the danger of heart attack and stroke
Sleep deprivation can also lead to the increased heart rate.
Whether for a healthy heart or better concentration, maintaining the sleep hygiene is quite important. In the age of the internet and smartphones, people tend to stay awake for long hours. As a result, they are unable to have the required amount of sleep at night. The key is to shut all distractions, such as, laptops, phones, TV, etc. few hours before the sleep time. If you are required to get up at a certain time every morning, clock your sleep time accordingly.
Wishing for good health is not enough. You need to take a good care of yourself to enjoy the optimal health not just in your younger days but throughout.
